Re: Imported Images Are Darker
Thanks Chipp! In PS 5.5, I changed the gamma from 2.2 to 1.8 and the images in photoshop now look the same as in Rev. ...on a Mac. I think the default gamma setting was changed in PS to more closely match the default setting for the other 95% of computer users. I'd be interested in hearing how the images appear in Windows. Personally, I run my Mac at 2.2 so I can see the world as most others will see it. Yes Richard, you're correct. This was on a Mac. I sort of forgot about the whole gamma issue and was glad to be able to know why the images appeared differently in PS and in Rev. In fact, the images in Rev while on Windows look the same as they do in PS, but not the same in Rev on a Mac. Now that I understand the issues, I think in the future I'll use the 2.2 gamma in photoshop and for my cross-platform applications, design for Windows. Then I'll use the screengamma command when the app detects it's on a Mac to make the color appearance the same. I've long wondered: does the Mac use the non-standard gamma for an objectively verifiable benefit, or was this just another Jobs thang? Good question. I have no idea. :-) Regards, Howard Bornstein D E S I G N E Q www.designeq.com ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

Hence mid grey value 127,127,127 would appear on the monitor noticeably lighter than 'mid grey'. So for print work it seems Apple's choice is a good one. For multimedia work, though, the difference leaves us having to choose between making things pretty for the Mac audience or the Windows audience, but I don't know of a way to get optimal results for both. :( -- Richard Gaskin Fourth World Media Corporation Developer of WebMerge 2.1: Publish any database on any site ___ [EMAIL PROTECTED] http://www.FourthWorld.com Tel: 323-225-3717 AIM: FourthWorldInc ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

Bill, have you tried setting the gamma correction value of your PNG images in Graphic Converter? The standard setting for Mac OS 9 is 1.8, and for Windows it's 2.2. Many graphic artists set their images to 2.0--right between the two standard settings. An advantage to using gamma correction is that, once it's set to your liking, your images should display almost identically across platforms.

Imported Images Are Darker
I am converting a number of my older projects from Director to Rev. To prepare the art, I copy it from the Director cast and paste it into Graphic Convertor where I can do the necessary scaling, trimming and conversion to .png format. When I import these images into Rev as controls, however, I notice that they are noticeably darker than the original art. Has anyone experienced this? Could it be related to the difference in bit depths between the images and my stack? Cheers...
