When I got my Macbook about 9 months ago one of the first things I did was change the default OSX screenshot format type from PNG to GIF. I edit a lot of images in Photoshop to post in technical articles and for the GIF’s I have been having to change the Photoshop Image Mode from Indexed Color to RGB to apply most filters during the process of editing the image. Photoshop loses a lot of functionality when an image’s Image Mode is set to Indexed so each time I modified an screenshot image and say wanted to apply a filter I would first have to modify the Photoshop Image Mode from Indexed Color to RGB. I recently got fed up with having to do that so I was looking for a solution when I realized if I just change the default screencapture format back to PNG the images open in Photoshop with the Image Mode set to RGB or Red/Green/Blue Color Model. Anyhow when doing so I started to wonder what image formats were available to set as the default screencapture format. Below I describe the details of what screencapture image formats are available in Mac OSX Lion and also what Image Mode that Adobe Photoshop opens each format from the Mac in.
Another OSX screenshot setting that many people may want to change is the file format that screenshot saves images in. The default file format for screenshots in OSX is PNG however I personally prefer GIF’s to PNG’s so below is information on how to modify the default PNG file format for screenshots to GIF.
Recently I had an issue where I needed to take a screenshot of an entire web page and since my monitor is fairly small on my laptop this is typically a pain. Luckily I discovered a Google Chrome Extension that makes accomplishing the task of taking a screenshot of an entire web page very easy. Below I describe installing and using the extension, which is called Screen Capture and was created by Google.
Recently I was trying to paste a screenshot created using print screen into Adobe Photoshop CS4 on Windows XP but nothing would happen. I use print screen to create screenshots on a regular basis and then paste the results into Photoshop so I can describe how to resolve basic issues on a computer to people. I have never had a problem until this time so I figured it must be a configuration setting or something similar causing the issue.
I have an iPod Touch 2G that is fairly messed up and both the power button and home buttons are currently not working properly which makes taking screenshots much harder than normal in iPhone firmware 2.X and 3.X. If you have installed Cydia however on your iPhone or iPod Touch then you can launch the screen capture from the command line without issue. Once you have taken a screen capture you can then email the photos to yourself or SCP (Secure Copy) them to your computer. To launch the iPhone screen capture utility from the command line follow the directions below.
