Dear all: I have posted this question to the Photoshop forum but haven't received answers so I decided to post it here now to see if I can receive some suggestions. After scanning several (hundreds) of slides with Nikon 35mm scanner using its own software (Nikon Scan) I noticed that the TIFF images displayed in Bridge appear with a very pixilated, low resolution quality. I have tried rebuilding the cache but it has solved the problem. It seems to me that maybe the Nikon software generates low resolution thumbnails for the images files and then embeds this thumbnails in the TIFF files. Could this be the problem ? I am running the latest software and drivers for the Nikon scanner, and Photoshop CS2 with the latest updates. The raw scans have approximately 130-140 MB in size. After I crop, edit and downsample the images the files are reduced in size to 70-80 MB. I have tried both file sizes and in both cases the images appear with the same low resolution on screen. Do any of you know what the problem may be here ? The problem appears to be related to Bridge. When I opened the image using Preview (Mac OS X) it appears fine on screen. The same happens with other software. Is there a preference in Bridge I haven't yet seen that allows one to specify the size of the previews or thumbnails ? In case this is not the problem, is there an application or script for Photoshop that would allow the embedded thumbnail in TIFF files to be replaced with high resolution ones ? Thank you in advance for your help, Joseph Chamberlain
