I used macro tubes plus a macro lens plus an inverted lens to get the maximum magnification.
This whole structure was installed on a slider, which in turn was on a tripod.
Filmed with the help of the IR remote control.
But the problem lies in 2 things.
Slider movements should be very slight.
And the most important thing is that from the front lens to the focus object is less than a centimeter and it touches the leaves.
Yes, very slight adjustment to the focus (for stacking). Did you try it with the lens stopped down as far as it will go? At least F16, F22, F32, in AV mode, let the camera set the shutter. That might give you a little more depth of focus for a non-stacked image. These are indeed very tiny flowers, even for Pleurothallis. I may have an image or two of Pleurothallis orchids in my archive, I'll look for them, I recall some very tiny ones (Pths. brighamii, I think).

Here you can see how everything was arranged.
With this optical scheme, a clamped aperture does not significantly increase the depth of field.
On the contrary, it significantly reduces the amount of light.
I had to postpone shooting, waiting for the vibration caused by the movement of the slider to subside.

Yes, it does reduce the light, but you compensate for that with a slower shutter speed.

Here's a Pleurothallis from my archives. These flowers are slightly larger than yours, maybe 3 or 4mm.

Wow...most interesting! I think it's a Pleurothallis, but A) it's a monstrously huge genus (+500 species) and B) I really don't know a lot about them. Thanks for sharing!


Couple of suggestions, based on my experience trying to photograph tiny orchids... a tripod is absolutely necessary, and a macro lens so you can get as close as possible. Use aperture-preferred mode and stop the lens down pretty far -- F16 at least, F22 or even more. Let the camera set the shutter speed (not a problem on a tripod). The small aperture give you more depth-of-focus. I have no experience with focus-stacking, but there are some examples of my images here in this thread using these techniques.
I learned the name of this orchid from my sister. You were right, this is Pleurothallis Stenostachia

Ah, good. That was a well-aimed stab-in-the-dark, then. Many of them are quite tiny flowers, very small plants. I presume your sister grows them? Maybe in a terrarium?

Oh how beautiful! Wonderful tropical garden in there! I see many many interesting plants, some familiar, some not. An excellent collection of fascinating plants! Congratulations to your sister for maintaining such a treasure!

No idea, either, but it's very pretty...I wonder what the flower will look like when it's fully open?

This is Pholidota imbricata, "rattlesnake orchid", from the Nikon archive. These are the buds, soon to open to little white flowers...

Actually, this is a blossom from one of my wife's, "Meyer Lemon" tree plants. Today will be an ideal opportunity for a tall glass of ice cold lemonade with temperatures expected to reach into the high 90s. Come on over enjoy some with us. Love to have you. )

Ooo..you cheated! You knew all along what it is! No fair! But you can shoot it again when the flower is fully open, and then later when it morphs into a lemon...

Thanks for the invite. A cold lemonade would be a treat! Pretty hot here, too, not at all typical for our summer weather. Hot and muggy, without a doubt, but NOT 95F...that's Orlando weather, not Miami weather. In June? This does not bode well for August...

Not true, not true. I must confess, I had to inquire as what type of flower this is.

Thnx,
