Black screen in Lab Color Mode

[hotchoclo]

Hello all,

I'm having an odd problem with Photoshop CS3 and Lab Color Mode.

When I convert an image from RGB to Lab, all I get is a completely black image.

According to this flickr thread, users speculate whether it having to do with the Adobe Camera Raw version, Graphics Card type, or actual camera used...

I have Adobe Camera Raw 4.1, Photoshop CS3, Canon EOS Xsi (450D), an Nvidia GeForce 6200 video card.

Has anybody else had this problem? Anyone know how to fix it (if it can be fixed)?

simply download and install ACR 4.3.1
