david-m Posted January 25, 2006 Share Posted January 25, 2006 I have been happily converting scanned 16 bit images into 8 bit (using PS CS2 on a Mac G5) until today. In PS under image-mode, it confirms that I have converted to 8 bit, but when veiwed through bridge it says I still have a 16 bit image. Duh, any ideas. I have tried saving, closing down bridge and re-opening but still says 16 bit, even though it also shows it as being half the file size of the 16 bit image. Any ideas please, as I want to submit some images to a stock library and I am concerned they will veiw it on (eg) Bridge and see it as a 16 bit image, so reject it Thanks David Link to comment Share on other sites More sharing options...
ellis_vener_photography Posted January 25, 2006 Share Posted January 25, 2006 Why would they reject a 16 bit image? Are you saving the 8 bit version in a different folder perhaps? Link to comment Share on other sites More sharing options...
denisgermain Posted January 25, 2006 Share Posted January 25, 2006 worst comes to worst....1. open the file2. Select All3. Copy4. Create a New Document5. Paste6. Double check to make sure it is really set to 8bit7. Save as Link to comment Share on other sites More sharing options...
david-m Posted January 25, 2006 Author Share Posted January 25, 2006 I am just converting and saving, so it's the same image in the same folder. The library specifically asks for 8 bit, as this is what a printer would require from someone who buys it. if it is a 16 bit image at (say) 50mb then the client or library may reject it as being too small when converted down to 8 bit for printing. This is driving me crazy, as I have spent weeks doing this same proceedure with no problems. Just baffles me. Regards David Link to comment Share on other sites More sharing options...
ellis_vener_photography Posted January 25, 2006 Share Posted January 25, 2006 I am having trouble understanding why you'd ever want to overwrite a 48 bit file with a 24 bit version. At the very least I hope you are archiving the 48 bit version in another folder on another drive even if it is just on a CD-R or DVD-R Link to comment Share on other sites More sharing options...
Ed_Ingold Posted January 25, 2006 Share Posted January 25, 2006 Bridge is refering to an old preview data. Try refreshing the preview. Link to comment Share on other sites More sharing options...
david-m Posted January 25, 2006 Author Share Posted January 25, 2006 So what is happening is - when I batch scan slides (using Nikon 5000 and SF210) with Nikon Scan, it embeds 16 bit info that does not seem to be able to be changed with PS, but if I batch scan though Twain in PS it converts to 8 bit with no problems. Trouble is that when I use Twain through PS, I am unable to check the box that 'saves to file' in the Nikon prefs, so that they the new scans (130mb) pile up on the desktop until the computer freezes (I have 1.5GB of RAM). Aaaargghh. Surely someone must use the batch slde feeder with the nikon 5000 and a G5 with CS2 - surely. Any thoughts please. Thanks David Link to comment Share on other sites More sharing options...
