Photoshop and image sizes? Just wondering.
Posted on 1997-09-07
I was just wondering: in PhotoShop 3.0, the preview box in the bottom left-hand corner shows my image sizes as twice what the finder says they are.
To be specific: 400 x 286 pixels x 3 channels: PhotoShop quite logically tells me I have a 400 x 286 x 3 / 1000 = 343K image. The finder tells me it's 170-odd.
Also the PhotoShop Bible tells me that the _second_ number in the box should be the same as the first, if there is only one layer. It isn't, it's slightly smaller: 315.
This isn't an actual problem, but I'm forever converting from RGB to indexed for the web and checking out the size, but the box is giving me weird information -- am I crazy, or what?
