There is a new Mac utility out that greatly simplifies and accelerates the process of taking and naming desktop images.
To get the basics out of the way, the app is called Sharpshooter 1.1 and it requires OS X 10.4 or later. Version 1.1 works with Snow Leopard. There is a 30 day trial available and it cost US$15. It supports the following languages: English, Catalan, Czech, Danish, German, Spanish, Finnish, French, Greek, Hungarian, Italian, Japanese, Korean, Norwegian, Dutch, Polish, Portuguese, Romanian, Russian, Swedish, Ukrainian, Simplified Chinese, and Traditional Chinese.
To get the most effective use out of Sharpshooter you should follow the set-up directions so that the application automatically opens when you turn on your Mac.
With Sharpshooter properly installed, each time you take a desktop image, either of the entire desktop or of a single window, Sharpshooter automatically opens your picture.
You are given the date and time you snapped the image in a field that also allows you to name the image. You can keep the date and time info or delete it while you name your screenshot file.
The Where pop-up menu allows you to direct exactly where you want to save your image, and the Format pop-up menu allows you to choose the format you save it in. The options include BMP, GIF, JPEG, PDF, PICT, PNG, and TIFF. Extensions are automatically attached to your images unless you check the box excluding that feature. I love this feature. I would buy this application for this feature alone.
Sharpshooter doesn't include an option to show the mouse pointer in screen captures, but for me, opening it in Preview and adding an arrow is more effective anyhow.
Anyone who teaches or publishes or asks for help or has any other reason to frequently take desktop images should love this application. Over a period of time it will save you hours of time and frustration and that is what it is all about.
