Issues with RAW and Photoshop?

Digital camera's are using RAW format but this is not a common or universal standard. Every camera manufacturer has his own format eg. Nikon .neff - Canon .CR2,..

If you buy a new camera and/or using older versions of photoshop (CS2,3,4,5) it's possible the RAW format will not be recognised. For that Adobe made a more universal format, DNG (Digital Negative Specificication). Adobe created a DNG converter which has most recent RAW formats integrated and with this new format, photoshop older version's can still be used. 

For the link of DNG Converter see my blog page usefull links.
