So here are a few more pics through curved glass. They taken roughly 3 to 4 " away from the glass. Please feel free to critique them no offense will be taken This is only a discussion. I might add I am now using a considerable better camera.

Nice pictures and camera, that 50D and 100mm is quite the upgrade.

I'm not a huge fan of the flash but it worked well for you. I noticed you used a fairly small aperture but your DOF is still a little limited, perhaps you could try focusing on the center of the subject. Also in the interest of the thread perhaps you could try take a few top downs with that nice new camera for comparison. Plus you should take a few at a true 1:1 ratio (macro).

Sphelps I'm confused how did you know the camera I was using? And I'm puzzled buy the 1:1 ratio. I think it is 1:1 ,I'm using the Canon EF 100mm f/2.8 Macro lens. Or am I suppose to be like 1" from the subject? All tyhe photos are at different manual settings I've been experimenting.
Copperband was f/16, 1/250, iso 100
Mush was f/5.6, 1/20, iso 500
Y Tang f/9, 1/250, iso100
Ric was f/9, 1/125, 100
Here are a few top down through custom photo tube

Thanks, Carmen and Leah I'm still figuring out this camera so hopefully they get better. I'm going to post some Fluorescence pics I took in a new thread you might like those.

Magic! Haha, jk. All digital cameras store data in each photo called exif data. This contains all the information about the picture including camera model, focal length, shutter speed, aperture, and so on. I can simply extract that data from any image with a simple plug-in on my computer. It's a nice feature to have because if you see a picture on the web you like, you can find out how it was taken, great for learning! If you don't have a plug-in or a program and don't want one you can use one of many online extractors. One is camerasummary.com

The 1:1 ratio is the definition of a macro/micro shot. If you look on your focus ring you'll see, along with the distance, a ratio (usually the closest focusing distance). If you focus on a subject at point you're at the 1:1 ratio and taking a true macro shot.

I apologize for not explaining this better but I simply assumed you knew all this because your pictures are that good! The best advice I can offer is for you to try and see what you can do without a flash. Top down will give the best results and you may need to use a tripod of some sort to steady the camera. You'll want a long exposure and a small aperture along with a low iso. You'll need to turn off all circulation to prevent your subject from moving but by doing so I'm sure your results will be even more spectacular.

Ahh, now I get it that's what they mean. I'm glad you like the pics. Thanks for the info and I'm going to look into a info extractor. I'm always wondering what settings pics are at. Thanks Shelps
