I can open my RAW files in Photoshop CS3 shot on Canon 350D, but now using Canon EOS 5 MK ll and downloading RAW 4.6 but get an alert Photoshop does not recognise this type of file, any advice please.
you need cr 5.2 or better for the Canon EOS 5 MK ll. ps cs3 cannot be upgraded beyond cr 4.6.
you can use the free dng converter (http://www.adobe.com/support/downloads/product.jsp?product=106&platform=Windows) or upgrade your ps (http://www.adobe.com/products/photoshop/buying-guide.html)
