Quick Tips


Well you may notice that in the Filter menu under Render there used to be a filter called Lighting Effects. Unfortunately in CS5 this filter will not work in 64-bit mode. You need to go to the application folder and locate the Adobe Photoshop folder. Click on the application icon and press Command-I to get info. Then check on Open in 32-bit mode. Quit Photoshop then re-launch. The filter should be available now.

    Hi Corey: Great job with Planet.

    Can you relook at your tip “Where did Lighting effects go?” ? the tip didn’t sound right to me, so I went and looked. I run only PS CS5 64 bit. Don’t even have the 32 bit version installed. I open all images as 16 bit files. When I looked at Filter/Render the “Lighting Effects” was greyed out. I switched the image mode from 16 bit to 8 bit and took another look. No problem, “Lighting Effects” was available.

    I think, what you saw was that when you switched to 32 bit PS5 it defaulted to opening images as 8 bit, so “Lighting Effects” was available.

    I believe the issue is more 16 bit image versus 8 bit rather than 64 bit program versus 32 bit program.



    BTW: I suckup everything you put out, both here on the Planet and over at NAPP. You must be working on a book. As long as it’s not about 3D I’ll be one of the first to buy it.

    I assume you mean Mac only? I’m on WIndows 7 64bit, running Photoshop in 64bit mode and lighting effects work.

    I have Windows 7 64bit and Photoshop running in 64bit mode, lighting effects works. I assume this is just a a Mac thing?

    I’m having the same problem, I’m running Photoshop CS6 32bit… I’m creating new 8bit files in RGB mode… but for some reason “lighting effects” seems to be blanked out, I don’t seem to be able to carry on with my project until I can use it

    Thanks in advance,

      If it’s a “Mac only” problem, then it should work with my pc, which is not the case. Adobe forum monitor said there is an issue with the power of whatever video card in your computer.
