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.
Tonight while working on a web site for a client I was generating a header image that needed to be a specific width to fill out the header properly. The font selected by the client had the letters smashed together so I needed to add some space between the letters. I am not much of a designer so I had to play around with Adobe Photoshop until I was able to find the correct settings which happened to be named kerning and tracking. Kerning is used for a single letter and Tracking is used for a group of letters. These options are located in the Photoshop Character palette and can be modified using the steps below.
I recently updated iTunes and QuickTime on my Windows 7 PC and afterwards noticed that when opening a .PSD (Photoshop Document) file that instead of opening in Photoshop the file opened in PictureViewer. I wasn’t even familiar with PictureViewer at first however after a little searching I realized that PictureViewer is now installed with QuickTime by default which is really annoying since I already have dozens of picture viewing applications. Anyhow what it meant was that I needed to modify how file types associated to applications which is what is described in more detail. I will first describe how to change a single file type to match a single application and then I will describe how to associate a single program to many file types at the same time.
I recently wrote an article on how to batch resize images in Adobe Photoshop CS4. If you have been reading any of my recent articles on the site you will know by know that I had a laptop hard drive crash and I lost some settings. One of the settings was the Photoshop Action I had created to batch resize images. Anyhow while configuring the Action I decided to play around more with Photoshop to see if there was another way to resize images and sure enough I found a better way if you don’t mind saving the images as JPEG’s instead of GIF’s.
