Photoshop 7 should be able to open an 16 bits/channel image that youv'e scanned without losing any more color information than photoshop cs6.
(some scanners call 16 bits/channel 48 bit color)
And Photoshop 7 can save 16 bits/channel images as psd or tiff files.
You should set the scanner to save the scan as a tiff file. RGB Color.
As you've no doubt discovered , editing an 16 bits/channel image in photoshop can be a challenge, so if you plan on doing a lot of those, you might consider upgrading to photoshop cs6 where high bit depth images are much
easier to work with.
I use an older version of Photoshop.
Uh, what version?
Thanks for your reply.
I do use the old Photoshop 7. Wouldn't the file have to be directly imported from the scanner though and not just opened with Photoshop? When its opened isn't it being recognized as an 8 bit file? Even if I then change it into 16 bit?
If you scan the file to a folder on your hard drive at 16 bits/channel, then photoshop 7 should open the file at 16 bits/channel.
What scanner and operating system are you using?
You should verify your scanner settings to make sure your actually outputting the file to 16 bit/channel.
(48 bit color as some scanners call it)
I scan in Operating System OS X Lion with an app called "Image Capture". My scanner has 48 bit capability and I think I am selecting 48 bit when I choose to scan at a high resolution and "billions of colors".
I have been scanning as tiff and opening in Photoshop 7 as a tiff. (I use a second older computer that uses operating system 9 to do my work on the photos with Photoshop 7.)
Not exactly sure how Image Capture works on lion, but i belive i read that since os x 10.5 that it should scan in 16 bits/channel
Are you able to use the software that came with the scanner instead of Image Capture or maybe you need to update your scanner software or
possibly check the preference in the Image Capture scanner preferences to use Twain Software When Possible.
Or scanner software like VueScan which is much better than most software that ships with scanners.
Anyway if the scan is saved as a 16 bits/channel tif as output by the scanner to a place (folder) on your hard drive, then ps7 should open it as such.
Thanks for your reply.
Photoshop did it. I scanned something in the "billions of colors" option to a folder on my hard disk, opened it in Photoshop 7 and it was in 16 bit depth. My only problem now is that my scanner is making mistakes with the photos when I choose billions of colors (doubling the image and altering the colors with a smaller picture and not finishing the scan and reading "scanner not available" with a larger sized photo).
Is that picture of menus and tool box above from Photoshop cs6?
The above is a screenshot from photoshop 7 on a older pre intel mac os x system, but it should be the same as far as the menus from File to Help as os 9.
I do have an os 9 system, but it only has up to photoshop 6 on it.
(photoshop 7 won't work on lion)
You might check to see if you scanner has any updated software for lion compatibilty or bug fixes.
Also the VueScan mentioned above has trial versions which may make your scanner work much better with lion.
I've heard good things about VueScan another place also. I'll try support from my scanner manufacturer too and see what they have to say.
Thanks for all your help.
