First RED HDR compilation

[im.thatoneguy]

I dropped all of the chart shots into HDRShop 1.0 and pumped out a floating point (32bit) OpenEXR.

I dont imagine this is useful, or in anyway something someone wants to actually look at. But if you want to... you can. Hooray for pointless technical exercises.

RED Chart HDR

Ooo, I may do the same in Photoshop's HDR assembler. Good idea.

It's kind of cool, but it would have been better if the source image actually had a wide dynamic range- the test charts did not cover such a large range in and of themselves. -well, there is one shiny pole on the far left (C stand?) that has a pretty bright specular highlight though, causing a ghost to its left- a secondary reflection off some lens elements, I suppose.

(edit) Actually it's pretty interesting- I'm not familiar with the extended dynamic range images (this is the first one I ever opened, in fact)- I notice that the funny pixels near the center of the star pattern (that I had to super-oversharpen to notice) are completely absent in the HDR image, I suppose adding together all those frames averaged them out. The colors are weird, but I assume that's just because I don't understand how HDR pictures work, exactly. Or each frame was very slightly differently aligned, from changing the lens T-stop?

That's just an alignment issue.

Yeah, the photos weren't taken from a perfectly still camera, so they don't line up properly and that throws the colors all off.

I also didn't assemble them very well and run any kind of camera calibration setup. Just... load "half stop" save. Then loaded it up in Combustion rendered out as an EXR and popped it online.
