NOTE: We only use Photoshop for creating images in pixel such as Photos. Graphics such as texts, logos and other artwork are always created in vector formats. Outlines.

Sharpen just the edges and leave the rest alone

The Unsharp Mask filter is a wonderful tool if you don't mind increasing the sharpness of everything, including textures. On the other hand, if you want the edges of objects to appear snappier, use the High Pass filter in combination with Unsharp Mask. To do so, duplicate your image and select Filter > Other > High Pass. In the resulting dialog box, adjust the Radius slider to accentuate the edges. Try the lower values first--the image takes on a gray appearance--and work up from there. Click OK. Then, change the Mode pop-up menu in the Layers palette to Overlay and observe the amount of edge sharpening that takes place without affecting the flat or textured areas. If the effect is too strong, try the Soft Light blending mode and/or use the Opacity slider in the Layers palette to reduce the intensity of edge sharpening.

Use the Measure tool to straighten out your images

When scanning images, you may have a scan that was a bit askew when you placed it on the scanner bed. It happens to us all. So, how do you straighten it out? It's easy; simply use the Measure tool. Just drag the tool's pointer along the top edge of your image, then choose Image > Rotate Canvas > Arbitrary. Click OK and Photoshop applies the information from your measurement and straightens things out for you.

Increase your canvas size relatively

The next time you have to increase the size of your canvas, check out Photoshop's Relative option. Just choose Image > Canvas Size. Then, in the resulting Canvas Size dialog box, select the Relative check box. Now, just enter the how much space you want added to the Width and Height text boxes. (avoid creating documents with random sizes).
