What image library/format should I use?

I am doing a new batch renderer and need to do image I/O including HDR (with viewer if possible).  Last time I did this it was all image magic and Greg Ward's rgbe code.   What are the cool kids using these days?

The kids might have gotten cooler since the last time I looked, but I believe it's OpenEXR.

I've used DevIL in the past. It is simple to use and supports many formats, including HDR formats, and can be compiled into a single big fat binary with no other dependencies. Not sure if it supports the latest OpenEXR spec or if its still "cool" :-)

All the cool kids (and, almost without exception, all the big VFX and animation studios) use OpenImageIO.

+1 for OIIO if you need something full featured with an out of core texture system.

If you are looking to minimize dependencies, stb_image is another popular choice (single file header library for C). pbrt-v3 is using this.

https://github.com/syoyo/tinyexr is another nice "micro library"

Thanks much for the suggestions! I am glad I asked. Nick Porcino added a vote for OpenEXR. I'll do some testing and report what I find out.
