Hi Andy, Rudolph and others,

Having just looked at Andy's excellent photo of his Cattleya, I ask this question.

How do you all get such a lovely contrasting black background? And I guess you mat all use different programmes.

I don't know how Andy does it, but I would like to :-)

My method, which only works for orchids which are easily moved around, is
to use a background of black velvet. This is described in the American
Orchid Society Handbook on Orchid Photography by Charles Marden Fitch,
which I bought about twenty-eight years ago... The most recent version,
dated 1995 and simply titled Orchid Photography, is available but I don't
know if the velvet is still recommended!

Thanks for all your comments.

I think my plant is rather less open than the one shown in the picture and I hope it is due to stress.

I got it from Elsner in Germany. I am always on the look out for species cattleyas and it is the reason I put in an order. Good plant quality by the way though some rather small to be described as flowering size. Regina Elsner did send the plants before receiving payment as with you Geoff and I had never bought there before. Nice that someone is trusting.

The black background in my pictures is a piece of plastic left ove from building the orchid house, covered in an old bit of sheeting and painted with blackboard paint − available from any of the DIY chains. You can buy non-reflective backcloths from photography suppliers but this is a cheap alternative.

By the way Rocky. I seem to recall we both had Laelia purpurata in flower at the same time last year. Mine has now got 4 flowers, eacdh measuring nearly 20 cm (8 inches) across.

I'm sure you'll get lots of response and help here and undoubtedly we'll all
offer different advice! My attachment aren't wonderful but I think they
illustrate the point(s).

Although I rarely submit pics to Orchid Talk I do regularly produce them for
other purposes (like the colour cover of our Newsletter). For a black
background I use sticky-backed baize-faced plastic of the Fablon kind on
board or card . They do a familiar green baize card-table flocked plastic
and a lesser-known black one. that is not always available because there's
"no call for it"! Much cheaper (I imagine) than velvet and easy to clean
(vacuum it) or replace.
However, almost any black non-sheen fabric or card will do but not a silk
textured one with a reflective sheen though, especially if you use flash
(not recommended)..

The other trick is camera exposure setting: Cameras don't believe you when
you show them a black subject and they give an over-exposure reading to
lighten it to a grey. Then, of course, your paler flowers are even more
over-exposed and 'burned out'. Therefore, make sure you take an exposure
reading solely from the flower itself (spot metering rather than averaged or
matrix metering), even if that requires that you take an exposure
measurement without the black background. Some cameras will hold the reading
if the shutter button is half-pressed and you simply use your third (!) hand
to slip the backdrop into place before final shooting or change your
camera's aim from a similar flower to the side at a similar distance (same
focus). If you have a camera with manual settings or an alternative way of
tricking it you won't need these contortions! Above all, avoid 'auto'.

Lastly, try to have the background far enough behind the plant for it to be
out of focus. That way, all those bits of fluff, cat hairs, beard hairs,
dandruff and biscuit crumbs will be far less noticeable than they are when
focused to pin sharpness . There is really no such thing available to we
mortals as 'dead black', all blacks reflect a little light and so it is
better to err on under exposing than over.

One of the great advantages of digital technology is that experimentation is
relatively free.

As for software; Irfanview (freely downloadable) will perform all the basic
manipulation you need and it does lots of other useful things too.

When I first got into serious photography , in order to record my orchids ,
a long time ago, I went to a local market and bought a yard and a half of
black velvet, ditto white velvet , ditto red velvet , and nailed them at one
end to a piece of wood , so that I could roll them up and keep the roll
conveniently in a corner of my work-room.
I can hang the strip up, via a highly technical bit of kit called ‘string
and drawing pin’ and have any of the three colours showing.
I don‹t use the red much, nowadays.
Black is fine for many orchids, but not for rather dark-coloured ones . It
is a good contrast which is needed.
But even then, if it comes to showing a hundred pictures, as at a talk to an
Orchid Society , any one background gets a bit boring after a time , so I
like to mix them up with some shots taken in the orchid house, preferably
with a background of all green leaves, and best if the leaves are out of
focus.
Note that even black velvet is unlikely to give a true dead black with no
detail visible, unless the exposure is done very carefully to suit the
velvet , and what you really need is exposure to suit the flower, which may
lead to every bit of dust or crease showing up . In that case you have to
work on the picture .
A simple way (assuming you have a decent soft-ware programme for the job)
is to duplicate the layer, select the flowers etc with a lasso tool , giving
say a 10 or 20 pixel feather to the marquee, delete the non-selected area in
that layer, go to the other layer, use levels, or curves or
darkness/brightness ( whatever you have got) to get the velvet suitably dark
and without detail .
Make sure that the selected image is the top layer, then flatten, size,
sharpen, and save as the final thing.
Actually, with experience, the whole procedure takes about as long as it
took me to type this.
If anyone wants more instruction on essential photoshop skills ( and
equivalents) I'll try to help.

Geoff.

It's hot enough Andy without spoiling my day any further ha, ha. My Laelia purpurta has not done well these last few months and I am at a loss to fathom out why, especially as plants stood beside it have done well.

Maybe it will tell me in the next few months.

Thanks for the useful tips! Your Disa looks lovely!!!

I sometimes just photograph my orchids in a dim room at night and make sure
that the background objects are too far for the flash to light up. That way,
I get a black background too.

Very sound advice; now I'm sighing for a seriously good digital SLR
camera, the (non-SLR) one I have doesn't allow me to take pictures the
way I want − it's all automatic with no manual override at all, I can't
even prevent the flash from going off.

But brilliant as your pictures (and those of others on the list) are,
there is one thing I miss: 'usefulness' for lack of a better word.
Unfortunately flowers are not all that useful for a systematic
determination of a species − especially of an orchid. Of course, if you
have seen a particular species often enough, you will recognise the
flower, but if you haven't, you have to refer to a botanical description
which means that the flower is not all that useful on its own.

A thing that can often make quite a lot of difference is if one takes
one or more less than perfect pictures showing leaves, stems flowers and
some object that allows you to judge the approximate size of the plant.

Hi JNS,

Sure is a very nice flower.

Now down to brass tacks.

Looks as though your plant has just one leaf to each pseudobulb, mmmmmmmm!!!

Flower could be mistaken for a type of Dendrobium brymerianum, but that has more leaves.

Only picture that I have found so far showing one leaf is that of a Flickingeria comata.

I don't think it fits either of them, but I will keep on looking.

Hi Jan,
I'm with you all the way with illustrating plants rather than flowers. The
examples I showed were simply to illustrate back backgrounds which are
fashionable or aesthetic rather than necessary. An image on a newsletter is
an eye-catching emblem or icon more than a species illustration.

However, the principles of exposing correctly for what you want to
illustrate hold for roots stems leaves or the whole. (See Geoff's comments
too.).

Cameras;- I use a Nikon D100 reflex camera but that isn't necessary the most
cost effective OR convenient solution for orchids and that's not why I got
it. May I suggest that you look at one of the many 'consumer' or 'prosumer'
cameras that (a) give you manual over-ride and (b) give you very closeup
capability. I am more familiar with the old Nikon 'twisty' Coolpix range
(like the 990, 995 etc with which you can get a postage stanp in full frame
at less than 3cm distance and independently control flash, aperture, shutter
speed and sensitivity as well as colour balance. Frankly, unless you know
that you need the facilities a reflex cam offers I think they are OTT for
most orchid work − unless you are into professional publication.

Reflex cameras really come into their own with action photography or flying
birds where instant response to the shutter button is paramount. Note also
that, unless you are a 'techi' you might find using one a bit daunting
because of bulk. Also, there is no preview (just a view through the lens
which is great except that it is diff to photograph upwards and closeup.
Also, you need maintenance care over avoiding or removing dust from the
electronic 'film' sensor which is exposed when changing lenses. The focal
length range of modern lenses focusing an a (usually) tiny chip gives them
versatility unknown with film.

Make sure you get advice from a orchid photographer rather than a camera
buff.

Maybe some others on the forum will chip in on this (or other) advice.

ps; Esther Koh (she might be in another forum) gives the very usefyul
suggestion that a black background can be achieved with auti flash if a pic
is taken in the dark and the background is too far away to be illuminated. I
haven't tried it with orchids deliberately but know of its effectiveness
when taking other shots by flash in the dark

Hi James

Some of this looks fungal but whether that's the cause or a secondary infection is hard to say. If it's all the plants I'd certainly look to culture method. How much air movement is there and are they waterlogged? I'd have them out of the pots to see the condition of the roots.

And what happened to them when you were away? There may be a longish delay between poor conditions and symptoms arising.

Hi John,

Thanks for the additional information. Which department of the university is
Peter O'Byrne? I was not aware that you were interested in an in-depth study
of the parentage of Ms Joachim.

Something else caught my eye − hookeriana is a swamp orchid! I've never
heard of orchids growing on water before. All my orchid-growing friends tell
me to make sure that the roots dry out in between waterings and here is this
orchid that has its roots permanently in water!!!!

Regarding the availability of light in apartments in Singapore, most of our
flats are oriented in such a way that the sun's rays do not shine directly
into the windows. Some even have structure above the windows to shield them
from light. The rational behind all this is that it helps to keep the flats
cooler. Unfortunately, it also means that highrise gardeners are perpetually
lamenting about the lack of sunlight.

Hopefully, you will be able to get Ms Joachim to bloom for you.

cheers,
esther

Hi Rocky,

Sorry, that I'm a bit late with my reply, but my telephone was dead for a
whole week, due to an exchange problem at Telkom.

I have 2 Phal. schilleriana's and both flower every year without problems.
I do not think that temperature is a problem as Phal schilleriana is
endemic to the Philippines and there the temperature is rather high than
low. I think it is a light problem.

Judging from the picture, I think it needs more light in winter to initiate
a spike.

All my Phallies get more light in winter due to the low angle of the sun,
as it shines then through under the edge of the shadecloth which is there
to protect them in summer.

Kind regards

I'm no authority on bugs or viruses but my reaction about quoted light wattage was that it is very little.
We have a 500w security light in our greenhouse (not for cultivation purposes) and occasionally, when it accidentally goes on in sunlight, we don't easily notice it! That seems to me to put artificial light into perspective − I think you need a lot of it. There must be basement orchid growers in the forum who could give guidance in this respect.

Hi Rocky,
I use a length of black flannel, 2 mtrs x 1.5 mtrs for all my
backgrounds. I also, preferably take photos in full sunlight
between 11 and 12 in the morning. I'm also much happier with
my 30 year old OM2 than with the new digital camera. With the
OM2 I can select depth of field and shutterspeed and I can use
whichever lens is suitable. With the full sunlight I get the
best colour and do not have to use a flash. However, nothing is
ideal. With the OM2 I have to wait until the film is full and
then get it transferred to a disc and then into my PC. With the
digital camera I take the picture go inside and load it into
my PC. Maybe the answer is a digital SLR, but it is a question
of available money. So, I try to juggle between the two. Use the
digital one for the medium to large flowers and the OM2 for the
small to tiny flowers, because there I have the various lenses,
extension tubes, bellows aso. Actually I'm waiting for Olympus
to bring a digital SLR with which I can use all the other attach-
ments that I have.

I checked the roots and they look good, a few bad ones but they are on
plants not exibiting any signs of diease.
there is a large open window in the room and a fan at the top of the stairs
to cycle the cool basement air through the house so i think airflow is
good. i have been growing in this basement for 2 years now and all my
plants except a couple cats have bloomed and grown well.
I just had a job doing a reno and removed 4 sets of flouescent light
fixtures that i kept and am going to be installing as soon as i figure a way
to hang them over the plants. I concidered upgrading to a 400W but i cant
afford it at the moment all it would take is a ballast and a new bulb
everything else would still work as it is, i might be able to get a new 400W
ballast through my work as we are going to be ordering a large number of
them in the next month.

Hi Esther,
An impression I had was, I suppose an assumption. Here is a quotation from
Peter;

"I live in Singapore, where I am a High School teacher. I used to live in
PNG (where I wrote "The Lowland Orchids of Papua New Guinea") and have since
published a book called "A to Z of S.E.Asian Orchid Species".

I have almost given up growing orchids since I moved house last year; I've
now got my collection down to about 30-40 pots/slabs of mixed tropical
hybids, plus about 10-15 species from mixed genera.

To tell you the truth, I don't really miss them that much, because for
several years I've been too busy to really enjoy them. I leave home at first
light and get back after dark, 6 days per week, and 7 days per week from
Jan-March. Never get to see the plants, let alone look after them properly.
I do, however, have access to a fantastic collection of species at the
Singapore Botanic Gardens, where I spend any free time that I have. I'm
officially a research associate ... ie, an unpaid assistant. My main task is
to identify the plants when they flower .... photographing them, drawing
them (if they are rare or undescribed) and helping to catalogue them.

In a way, this is better than growing your own orchids. Someone else does
all the hard work and has all the worry. I get all the pleasure and
excitement. "

Hope this clears up any misconeption! Sorry.
However,it doesn't alter my respect for P.O'B who has helped me with several
problems orchidwise.

Hi James, Bugs, virus or both. I would say both, especially on the virus
side, but can you get them checked out.

Burn the really bad ones and quarantine the rest. Isopropanol will only
kill certain bugs. Make sure you sterilise any cutting tools, blades you
use. Please let me know the results when you have them checked out for
viruses. It's not expensive.

The lamp brightness is not important on its own . The question is how near
to the leaves it is. And there can be a problem in that to get it near
enough to provide enough light, you also provide too much heat and the plant
cooks.

Hi Peter,

Many thanks for the tips that you offered to me and all other listeners. I have forwarded the Schilleriana information to my friends in Barbados and await their reply.

As to the 'What camera' situation............tell me about it. I like you, still have my old Canon and my old Mamiya. Both 35mm. And like you I have many different lens, tubes, bellows etc.

Technology has left us behind.

I'm still waiting for someone to accurately pin point a website for me so that I can actually look at a projector that takes a Memory stick, so that I do not have to take along a mass of heavy slides.

Peter, do you have a screw fitting to one of your digital cameras? I ask this because I bought one that screwed to the front of my Canon Powershot A20 and it is so easy to then take photos of slides, download them onto the computer and so on. The actual tube like screw on fitting is very good.

Orchids are growing well at long last, and I have four new growths on my Ansellia africana.

where can i get them tested for viruses? I live in BC Canada., i have never
had to do this nor ever hear of a testing facility.
I have been growing under these lights for over 2 years and every one of my
plants has flowered and grown well untill this last month when they all went
downhill.
i sterilize all cutting tools when i have to use them but i rarly have to
cut anything off my orchids except a spike when the flowers are finished and
i use a pair of scissors that get bleached immediatly after use.
i keep the 250w light about 2ft above the orchids any lower and the leaves
of the taller plants get too hot, the plants seem to grow well but not as
good as they would with more light.

James, You could do a Google search or the AOS Journal had plenty of
advertisements for virus testing. You only need to send a small piece of
leaf. Cost should be no more than $10US.

Many years ago I offered a virus testing service here in the UK, using the
ELISA technique, but only a hand full of people took it up. I analysed for
CyMV & ORSV for UKP5 all in.

I am sure Canadian members of the group can help but I will have a look for
you.

There are advertisments in the Orchid Journals about virus testing , from
time-to-time , and even testing kits.
They never catch on , probably because the price of a kit ( or a single test
, which comes to the same thing ) is about the same as the average price of
a plant.

Even if you were to spend the money on a test on a valuable ( expensive)
plant , it is rather a no-no situation ! If the test shows clear , then your
plant was / is even more expensive, and if it shows infected, you throw the
plant away having doubled its cost.

If you surf the web you can find very good illustrations of virused leaves (
leaves show , for example and without limitation- either ring marks which,
once you have seen them are easy to identify , or black streaks , which are
more difficult since poor culture can produce the same thing ) and even
flowers ( flowers are easy , they are deformed, spidery, twisted things ,
but often the result of virus is no flowers , so flower pictures are harder
to find).

And if you think it is more than likely the plant is virused, then a plastic
bag , sealed up , and into the incinerator or waste dispose, but do not put
it on your compost heap.

Geoff.

I don't think you'll find a dedicated digital projector − just use your
computer + some sort of projection monitor (similar to a projetor TV)

Some digital projectors have USB input facilities and can be 'fed' from a
Palm or hand-held PC.
I have a Flashtrax XT 80 Gig HDDdevice from which video, sound (MP3) and
.jpg files can be sent to a projector. This is a more compact facility than
a laptop but not as versatile and a 'slideshow', albeit manually or
auto-driven would have to substitute for a Powerpoint presentation. You cand
details and reviews on the web.

A few months ago we had a Society meeting at which a speaker demonstrated a
test kit for orchid viruses. Members had been prompted to take suspect
plants for testing. Of all the ailing unhealthy looking virally suspect ones
tested, not a single one proved positive for virus of any type. Probably
many visual virus symptoms are suspect and maybe we blame too many plant
failures on virus infection..

Hi, just a note all. The Nigerian Scam people are at it on Ebay in Australia. They buy an item, offer a much inflated price above purchase price from ebay and then ask for the item to be sent to Nigeria. NO payment seems to take place.
The current one operating has already been banned ( I believe ) from ebay but changes the user name and details and starts again.
Extreme caution must be used if you are selling anything on ebay.

Regards, Roy.

Hi James -
The lab I have used is in California, US. The cost ran
about $4/sample, with a discount of a dollar or so for
more than 10 tests. I believe they do a good job.

Roger, I don't know if it is me, Peter Fowler, you have emailed, as we have
a few Peters on the List.

All my cameras have screw fittings; I use them for filters mainly. I have a
slide attachment for my HP scanner, so I can scan and download to where I
like.

I had a Powershot a couple of years ago & I could download pictures to my
television.

They would have sent you all the cables etc.

Best wishes

Hi Peter,

Peter, do you have a screw fitting to one of your digital cameras? I ask
this because I bought one that screwed to the front of my Canon Powershot
A20 and it is so easy to then take photos of slides, download them onto the
computer and so on. The actual tube like screw on fitting is very good.

Around about 1992, when I had just started growing/killing orchids I was given a back division of Rhyncholaelia glauca. If you look at the plant photo you can count the remaining pseudo bulbs for each year of growth. At first it was in medium bark,moss and perlite and each year another small growth was obtained. Six years ago I potted it in large bark and there was an improvement. Three years ago I put all my Cattleyas and associates in hydroleca (clay balls) and 10% rockwool. All but the Rhyncholaelia went down hill. I repotted all the others but left the Rhyncho.
Eventually this year a sheath appeared and it was R. digbyana. Not only was it digbyana but a variety 'fimbripetala' 19cms or 7.5in wide
Photographing a white/green flower on a black background was O.K. but the full plant was a failure so my neutral background was used
Both are art mounting boards.

I have been using a digital projector for maybe 3 or 4 years now , and
whilst not an expert , I've picked up a bit about it, and naturally read
about whenever I see anything.

I have never heard of a projector which will work from an inserted memory
card or memory stick . The ones I know about are connected to a
lap-top/notebook /pc/mac, and simply project the image created , rather
like a second monitor screen.

If you only want to do this at home, then of course, you could use a DVI
output ( or maybe a video output an your tv screen. ( I have a 42 inch
plasma screen, and simply connect my lap-top , to show my pictures at home.
The projector was for use when I gave talks etc, at OS's. − and I probably
justified the rather ridiculous expense to myself, as a real need, when I
was writing my first digital photo book- I could only write about things
which I actually knew about )

I see that projector prices have come down a great deal − there was an offer
in an advert in the Times the other day − about UKP500 . I recall that I paid
twice that much. And incidentally when I bought , I tried a row of
projectors, everything the dealer could find under UKP5k each , and chose the
one giving the best pictures with my own image files which I took along for
the experiment − quite interesting that , I think !

Hi all,

On the subject of the dreaded word VIRUS, John wrote:

I hope that John's words will be a welcomed by many orchid growers all over the globe.

I well remember a case many years ago. I was visiting an orchid nursery. Three or four of us were busy chatting. One of the workers in the nursery was using a scalpel and he cut away a piece of a plant. he then dipped in it some liquid to sterilise it. We all continued to chat. The scalpel was waved about in the air as the holder demonstrated some point or other, as we do when we talk with our hands.

Later on the scalpel was used again....................................

Do you see what I am getting at?

Joaquim is a Portuguese name, not Spanish, as Rocky's informants seem to
think. Therefore the pronunciation should be Joakeen. I should know. That
was my driver's name!
