TIFF: 32 bit

[leoskats]

Hello guys. Hope you're good. I just make an edit in Affinity photo one raw image file and export it as a TIFF File. I discover that there is an option in "More" that has TIFF 32 bit. What that means? I export it but when I try to open this 32 bit TIFF i can see only black and some purple lines (probably there is a problem). I make edits in order to upload the pictures in internet and usually use the PNG-48 image file: does a TIFF 32 bit differs from a PNG-48 in terms of quality? Thanks.

You can‘t use tif in the Internet at all.

So Owenr you think that TIFF 32 bit is unnecessary. Also between TIFF 16 bit vs PNG 48 bit: what is better in terms of quality? Or both files are the same because they have the same lossless compression?!?!

Indeed, I believe even Owenr and I explained that in large extent, to more than enough depth . 

I don't think you are trolling, you could just have some sort of memory problem. In that case, there is no problem at all, just re-read all the thread as many times as you need it, even have it handy in your browser toolbar's bookmarks. As you seem to be very worried by this specific matter. Here is the thread :
