8, 16, 32 bit depth?
So I was speaking with a professional photographer and he was telling me that he uses 32 bit depth when he is editing photos. I commented on the fact that when you export to jpeg, it downconverts it to 8 anyways, so what's the point. He said when you're editing in 32 vs 16 vs 8, you have more info for editing and thus more… -
Re: 8, 16, 32 bit depth?
When the image gets to Photoshop look in the Image/Mode menu. It will either say 8 or 16 bits/channel because Lightroom as far as I know won't edit in 32 and so can't export 32. 16 is Lightroom's native bit depth and there is no place to change it. The only place to change it in LR is when you export, you can leave it as… -
Re: 8, 16, 32 bit depth?
I believe 24-bit true color is achieved with 8 bits for each of the RGB channels and is fully encoded in an "8-bit" JPEG. I understand your point about quantization error, but I think we have a long way to go before problems become apparent from working in 16 bits. By that I mean that beyond a certain point, more bits are… -
Re: 8, 16, 32 bit depth?
The issue with high bit display systems is the full display path is still 8-bits in some areas. The application, OS and so forth all have to support more data. So for example, even if the OS and hardware are all there, we have to have Photoshop support the data which currently, depending on the OS, it may not provide. -
Re: 8, 16, 32 bit depth?
Tell your friend that I have some $5000 speaker cables I'd like to sell him. RAW files are typically 12 or 14 bits, so all of the information they contain can be represented in 16 bits. PS itself has very few tools that can work on a 32 bit mode image and to this day, some of the filters only work in 8 bit mode. The one… -
Re: 8, 16, 32 bit depth?
Well the point is, there’s a lot out there besides JPEG and there is a lot of data being tossed that you’ll never get back and could use (Epson and Canon printers for example can send all the 16-bit data to the print driver). This may help: http://www.digitalphotopro.com/gear/imaging-tech/the-bit-depth-decision.html As for… -
Re: 8, 16, 32 bit depth?
It's not really that complicated, IMO. Complex edits, color space conversions, etc. when performed on images represented in 8-bit, can lead to significant and visible degradation. In the vast majority of situations, one can avoid those problems by shooting RAW and editing in 16-bit. I generally archive the almost-final… -
Re: 8, 16, 32 bit depth?
From what I have been able to figure out from trial and error, Photoshop 32bpc mode uses the ICC source profile as input and creates linear 32bpc working version of the input, 32 bit moves such as exposure are applied and then when one renders the image out of 32bpc mode - the image is converted to the working RGB profile… -
Re: 8, 16, 32 bit depth?
Sure, but you're missing the point, and by your logic 24-bit CD remasters shouldn't make any sense either, yet they are pretty much industry standard these days. The point of having greater bit depth for editing is that each time you do something to the image, the result has to be quantized to the bit depth you're working…
