Is there a version of the Photoshop RAW file format for 32 bit floating point?   Not Camera RAW!!!   At present, all I see only are 8 and 16 bit formats.  Be nice to have 32bit.

Comments?

Had already been there.  I need to move the 32bit files to another environment which they are now using 16 bit Photoshop RAW as the medium.  I was hoping I could change the script to do it.  How do I get Adobe to update for 32Bit Photoshop RAW?

Thanks for helping.

How do I get Adobe to update for 32Bit Photoshop RAW?

Have you consulted the Reference?

Quote:

The Photoshop Raw format consists of a stream of bytes describing the color information in the image. Each pixel is described in binary format, with 0 representing black and 255 white (for images with 16-bit channels, the white value is 65535). Photoshop designates the number of channels needed to describe the image, plus any additional channels in the image. You can specify the file extension (Windows), file type (Mac OS), file creator (Mac OS), and header information.

No mention of 32bit.

So how do I try to get the PS RAW format to handle 32 bit floating point?

It so happens using PS RAW output is the only efficient way to get a

binary file from Javascript. The client wants a binary flat file with 32

bit.

Thanks for your patience.

I have PS CC 2017 and I see where it is available now.   Would never have guessed.   Speaking of guessing, the user should be able to specify the aspect ratio and routine get number of pixels in x and y.

Someone needs to fix the various pieces of documentation -  see above.

Works fine in javascript now also.   Read and write work.

Thanks so much.

Why would Adobe not move forward with technology and the fast movmg future? Why would we have to go back to a very OLD version of Photoshop to do this? Does this make sense to people who are trying to push the boundaries of the cutting edge of the current place of technology?

The reason an old Photoshop version is mentioned here is that it's an old thread. When it was written, that was the current version.

 

What's your point? Do you have a specific problem that we can help you with?

In the Digital Negative (DNG) Specification document it says: "Floating point bit depths of 16, 24, and 32 bits per sample are supported."

With the most current version of Camera Raw, is 32-bit float point being used?
