A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

Can you add more light without adding more heat? (alien.top)

Does more light always mean more heat?

I'm trying to illuminate an extremely small dark space, but bringing my lights closer to the subject risks damaging what I'm photographing. (Using Apunture 600d LEDs with Fresnel heads).

I'd like to stick with continuous light if possible, since I'm also pixel-shifting for resolution in this series.

So I saw you were using Pixel Shift and that's why you can't use strobes.

Another solution is just change your technique and do the post-processing manually. There are plenty of tutorials online that show how to do super-resolution by simply taking a lot of images and stacking them in Photoshop.

If you do it right you can take a 10 MP camera shooting at 200 ISO and make a 100 MP image at relative 10 ISO. You just need to take a bunch of photos and stack them.

Good idea. I'm going to look at this. There might be issues with parallax if I'm moving the lens position, but if I attach it to an astro head and program it to move in the sub-pixel range that might work. Also just the variation in the strobe output may be enough . If nothing else I'll at least get noise reduction from the stacking.

I'm also doing heavy focus stacking in this series, so adding out-of-camera pixel-shifting will increase the image count to a few thousand per shoot... But I'm getting used to dealing with that quantity of data!
