soory to bring back an old thread but I'm wondering something. I saved my renders in openEXR 32-bit and made my post work in photoshop with ArionFX. I want to put these images on my website but I noticed pretty much everybody have jpeg... Am i going to have to skip the 32-bits and ArionFX tonemapping for my internet stills? It would suck.

Hi there

keep your workflow as it is.
At the end convert your 32 bit image to a 8 bit and make sure to use the EXPOSURE AND GAMMA method (default settings) in the "HDR toning" pop up window.

It's intermediate format. You're still supposed to output your post-produced final into common web file format like jpeg or png(8bit version). There is no visual difference (most people do have 8bit or 8bit + dithering monitors anyway, and only people with Quadro/FirePro with unlocked 10bit per channel ouput, and widegamut monitors allow for broader color pipeline), the .exr only allows to store more information (16-32bit per channel) in linear gamma for compositing purpose.

I recently started to save my corona renders in 32-bit openEXR to make my post-production with ArionFX for photoshop. My problem is my pictures are destined to my website...and afaik websites usually contain jpegs. I cannot save in jpeg, just tiff and some other formats.

Is it possible to put 32-bits tiff on website, I guess it's too heavy. I don't feel like abandoning my ArionFX and do my post in photoshop. :-(
I tried to change the 32 bit to 16 bit but it f**k everything related with ArionFX. Is there a special trick...

Thanks

You digged out the old thread 1 hour ago, got a reply but opened another thread.

Any sufficiently advanced bug is indistinguishable from a feature.

I too find EXR abit limiting when having to save out to other formats in PS.
I have ditched EXR. Instead I save to HDR (radiance image) un-clamped, in Corona. Then you can use it in ArionFX.

Hi ;)
I got some question in working with HRDIs in Photoshop and didn´t wand to start a new thread for an "offtopic". I saw a video of Grant Warwick perfoming layer actions on an 32bit HDRI. When i open an HDRI nearly every option is grey and i can´t use it.

He uses a mask on an exposure- layer which i can´t create in 32bit. When i change to 16bit most of the colour information is missing :( The other option i have is to change the exposure without getting a layer, but in this case i can´t use a mask :(

Is there a workflow to fix this issue?

Adobe CC is the answer. Lot of the options were unavailable in CS6, in case you're still using that.

Funny but it looks like it can be done in CS4 but not in CS5.
