Yesterday I read an article on location data that is included with all images taken on your iPhone. This type of location data, which is also known as Geo Data or GPS Data, is included behind the scenes on all sorts of media that you create on a day to day basis so while I knew this and was familiar with the type of data that is included I had never spent much time looking into this data. Since I typically use Adobe Photoshop to edit images I figured I would start there and see how I can view location data for images taken on my iPhone within Photoshop CS5 which is the current version I am using.
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.
Today I was working on getting multiple versions of the same application running on Mac OSX 10.7 Lion and wanted to add both versions of the application to the dock on my Mac desktop. To minimize confusion for which version of the application I was running I needed to modify the application icon so it looked different in the OSX dock. Follow the directions below to modify the icon of a specific application on your Mac.
I have been using a Mac now for a little over 6 months and at this point I am pretty used to it however there are still things I find that I want to customize to be more how they used to work when I used Windows as my daily driver. The great thing is there is always a way to make it work on OSX and that was not always the case on Windows 7. I edit a lot of images for articles that I post online and so I am constantly using Photoshop and one thing that has really been annoying about Photoshop is the fact that it has a transparent background by default on the Mac. I always figured there was a way to set it but never spent the time to look but that changed tonight and below I describe how to set a grey background for Photoshop on the OSX just like how the Photoshop default background is on Windows.
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.
