saving 32Bits TGA when opening in PS it's 8Bits!!!

[lukx]

I need to work in 32Bits but when saving files as tga 32 bit, when opening in PS it's says RGB/8 ! How I can save 32 or 16 bit TGA from 3dsmax?

The TGA is 32 bit's per pixel total - 8bits per channel for RGB and an 8 bit alpha. I'm not sure there's anything higher.

channel depth are only available with other standards such as tiff, exr ecc..

Isn't tga a bit antiquated? I thought it hadn't been updated since the late 80's or something.

And these guys are right. If you want 32bit floating point images you might try tiff, exr, or hdr format. Note that tiff won't hold alpha with 32bit btw.

I use TGA most of the time unless I need FP images. What's wrong with TGA? :P It's not like PNG which seems to be treated differently depending on the program.

I've just been using png for animations because it's quality is great and the size is small. Yeah, it's a bit annoying that photoshop doesn't like to read the alpha the way we want. although, if that's a problem it's not a big deal to open in in afterEffects first then move it to photoshop.

I used tga in school when I used maya and for some reason about 1 in 150 frames or so were corrupt and I would have to rerender. After I stopped using tga that went away. My teacher taught us to use them. I asked around about the corrupt files and people advised to just use a different format. They suggested png. I did some tests to see what was the best quality and png was one that I didn't notice any quality loss.

Tga is one of the simplest

Tga is one of the simplest fileformates for images data structure wise.
In a sense there is very few possibilities for screw ups and great application support.
But it is also only loss less run lenght compressed.

Png is a pita since the alpha premult and gamma curves get interpreted differently across apps and os. Rather go exr or tif than png.

my 2 cents
