how do I download and install camera raw plug-in 7.4 to support Cannon EOS Rebel T5i in CS3 Photoshop v10 ?
CS3 can not use ACR 7.4. Download Adobe DNG converter and create Adobe DNG Raw file for you CR2 files. CS3's ACR 4.6 will be able to process the DNG files.
Thanks for the information. It is very helpful.
