Photoshop 101: Editing Indexed Color Images from the Web

Jay Hilgert — Mon, 01 Feb 2010 20:29:29 +0000

Have you ever plucked an image from the web and tried to edit it in Photoshop only to find annoying problems? It’s probably a .gif in Indexed color mode. For this quick example I’m using the MediaTemple ad in my sidebar, which happes to be an indexed .gif.

When trying to edit an indexed color image in Photoshop, certain adjustments are disabled, as you can see below.

The quickest way to tell what you’re dealing with is to glance at the Layers palette. You’ll see right away if it’s an indexed color image.

All you need to do in order to edit your image is simply change the color mode to RGB, and all of the annoying disabled features return.

35 Stunning Hi-Res “Public Domain” Astronomy Images

In the wake of Shepard Fairey’s debacle with the AP over the rights to the image he used as reference/inspiration for his wildy popular Obama poster, I wanted to share a list of Public Domain Licensed images, in this case, astronomy. Fairey’s situation should hit home with all pixel junkies out there and remind us that we have to pay close attention to the licenses associated with the images we use in our design work. I’ve compiled a list of beautiful, inspiring astronomy images that all have a Public Domain License.

Astronomy intrigues me. I’m a regular APOD surfer. I love reading about space, and the images of the universe, I find inspiring. Here’s a list of “Public Domain” astronomy images that I put together, all of which I found on Wikimedia. If you aren’t familiar with Wikimedia, it doesn’t have a stellar (pun intended) selection, but it’s a very good source of Public Domain and GNU licensed images. So here we go, let’s start off the list with none other than our very own blue marble.
