I shoot last weekend using RAW for the first time on my Canon 40d. I couldn't open the CR2 file with my Photoshop CS2 on my laptop, and was prompted "Could not complete your request because it is not the right kind of document." I was told that CS2 is not the updated version, meaning I have to upgrade to CS3.
So, the next day I tried opening photoshop CS3 at my workplace, and still it doesn't work. The same message pop-up appear. But then my friend can open my files with her CS3 (I gave my CF card to her).
What exactly the problem is? How to solve it? I just bought my 40d earlier this month and no firmware was update or whatsoever....Is there a necessary action to update firmware of 40d by the way? I'm totally unaware.
And I never install any softwares given with the Canon disc either because I thought photoshop has the capability to do so with the RAW files.
Please advise. Thanks.
