Whatever that is following your bottlebrush, that's my favorite of yours so far.

It's basically the top part of that bottlebrush which I suspect was the remaining bud?

Got both my filter cutouts yesterday. Now both my convoys have inbuilt filtration

I'm mostly certain the bottlebrush I did entirely lacked that bit. Hmmmm.

Ahh, having just referenced mine, I believe it would become fuzzy leaves from the tip of the flower bunch. Maybe your flower was more youthful!

It's been a while since I posted. Less time to shoot and share. I have photos from May still to edit. The canterbury bell at the end is the first I illuminated with my Convoy light. I did another set last night and my old 10-led UV rig broke during it, so I was really glad I had the Convoy then.

I gave up on the Nichia route after not being able to find anyone willing to sell me the metal circuit board needed and have ended up designing one to use LG Innotek LEDs which are supposed to be on par with the Nichia, but much less costly. I won't know how it performs until they arrive, but I am looking forward to it.

This is also the first set I've posted using my A99, for all the images after the lavender. It is such an improvement over the A77 for me, though from these size of images, it may not be so apparent.

French Lavender: #165-167







White Daisy: #168



Salvia Leucantha: #169-170





Palo Verde (Desert Museum): #171-172





Larkspur: #173-174





Aloe: #175-177







African Daisy: #178



Patterned Geraniums: #179



Carissa: #180



Umbrella Grass (cyperus alternifolia): #181-183







Yellow Rose: #184-185





Canterbury Bell: #186-187

As always I've been enjoying the recent posts here. Forgive me for not commenting lately but you (both) probably don't need me repeating "Lovely - TFS"!

I've just realised that one of the differences between your shots is that you, Anand, seem to use more dramatic lighting whereas you, Craig, seem to me to favour softer light. Is that preference or equipment?

Oh, and, Lovely shots - TFS!

Mostly preference for me. I use long exposures to fully paint the subject. Since what we're photographing is the flower's glow rather than reflection, I really want to emphasize that fact by avoiding intense shadows. My old light had a huge spread on the UV radiation so I wouldn't've had a choice.

With the flashlight I can spotlight specific parts, but I also like showing the relative intensity of glow with some accuracy, so I mostly try to keep it even. The canterbury bell is the only one I've done that on.

Your absence was noted! But forgiven.

All of these new shots are wonderful but #190 & #195 are absolutely exquisite. DoF is tricky with macro (& similar) but you use it nicely. (Do you ever focus stack?)

194/195 are two of my favorites ever. The white cyclamen is one of my favorite flowers of done of all.

I rarely focus stack because the flowers themselves move slightly even if there is no breeze. I have an abutilon flower yet to post which is focus-stacked. Mostly of late, I have just been pushing my F-number (~F16-F/20) since I have the Convoy light.

I finished building my 25W UV light using LG Innotek LEDs and it's ~16x as potent as that single flashlight is. I have only used it on one set so far, but I cut my ISOs from 400-1600 to 100-400 and simultaneously was able to lower my exposure times.

Another great set Craig.

#199 seems almost classic to me, but I'm really drawn to the colours in #197.

The cereus in mixed light was interesting. That was the first time I've tried UVIVF in the field, including street light pollution. I had to take about 5-6 images where I concentrated the light on one part, and blended them later.
