The face of a drumming katydid (photo)


Hi all,

OK, I think I have sorted out the problems I was having with stacking images. The photo below is of an immature drumming katydid (Meconema thalassinum) that I posted on my blog last night. It is compiled from a stack of 41 images. Its head was no more that 2 or 3 mm across. What do you think?

Now it is time to move on to some other subjects. I especially want to spend more time photographing aquatic insects...so I should be posting pictures of more "wet" critters soon...

Cheers,
EC

Why did you need 41 layers?

layering photos of different ISO values allows one to capture a 'whole' image

Actually the ISO is the same for each picture, but the focus is slightly different. When photographing at high magnification you have very little depth of field. By combining a lot of images you can create a photo with everything in focus...something you couldn't achieve with a single picture.

That's a new one on me.

EWTC how long did it take to shoot all 41 shots? Better yet how did you get it to stay there for 41 shots?

I am of course assuming you used PhotoShop. Which version?

I'd love to see the layered file.

That's fantastic Ernie! Did you use a rail for your camera? Move the subject? Or the focus ring? Auto-blending in PS? Or did you manually mask? Great stuff.

Going to try that with flowers...

Nice trick. Now to find a bug that will stand still for all of that. I'll have to play with that.

photo stacking is fun and the outcome can be quite rewarding. Kudos for being able to do it on a live subject. Something I've yet to try myself.

As Wasserpest asked, I'd also like to see your 'rig'.

my apologies, my girlfriend is the photographer! i sat through her layering and stacking landscapes and various other shots, to bring out various details lost with high/low ISO values.

I assumed it was the same principal, but the depth of field makes sense. thanks for the clarification

Focus Stacking

It's a very neat trick to have in your arsenal. I try not to use it often as it can make shots look fake, but our client asks for it once and a while so it's nice to know how to do it.

Yes... instead of focus stacking, HDR stacks different exposures of the same subject.

Yeah but 90% of the HDR I see looks like crap. People tend to overdo it. Done correctly it's great.

I found a stunned dragon fly on the ground. I posed it onto a leaf.
My version of photoshop doesn't have focus stack so I did it by hand.

I didn't use a tripod so it made things a bit difficult.
