Probably a victim of weeding out legacy code and the respective changes in the underlying math. If it opens up elsewhere, why not simply convert it there? Seems a bit odd to me to scan them to fax TIFF in the first place when you plan on further editing. The engineers I work with usually only use it for archiving drawings or creating print sets from their vector drawings, but scan to normal greyscale TIFFs if a legacy drawing needs to be reworked.
Many thanks for the prompt reply.
I agree with you... it's a little odd to save on fax tiff format... to be honest, it's not like we have an option on the matter... the XEROX 6204 Large Format Printer/Scanner either give us .Tif or .PDF options... Anyway's no problem with CS3 or other software like mentioned above... so even knowing it's a bit strange to use such format, still does not explain why on CS5 I get this error message. Furthermore if I open on CS3 and save as (same file name and same format .tif) I can then open on CS5!!!!
To my surprise, I did not know it was saving as a fax tif... all I get is tif. Even so if all other software including an older version of Photoshop can open it why CS5 can not? What is missing? As mentioned if scanned at 300 dpi it opens... Confused. Very confused!!
All the best
You get the message in CS5 because CS3 was not doing error checking correctly and could crash when opening larger FAX encoded images.
