If you are anything like me, you can figure out how to use most Photoshop tools pretty quickly on your own, thank you very much, but the challenge is finding where in the menu structure the BLEEPIN' tool is buried in the the first place. And "help" is no help unless you know the correct name/term to search on.
With that in mind, I present my list of Five Essential Photoshop Tools ... And Where To Find Them. I'll refer to Photoshop Elements 5.0 in this blog, I think that's what alot of folks here use, but, with some excpetions, the tool locations are pretty uniform throughout all versions of both Photoshop Elements, and Photoshop. In Elements 5.0, these tools are available in the "Full Edit" tab ... forget about "Quick Fix".
1. Resize an image: Found under Image -> Resize -> Image Size. I always check "Resample" so I can type in the actual pixel dimensions.
2. Crop: Found under Image -> Crop. Or use the Crop icon in the toolbar.
3. Adjust contrast/lighten/darken: Found under Enhance -> Adjust Lighting. Play with all three functions under adjust lighting: Shadows/Highlights, Brightness/Contrast, and Levels to see which tool does what the particular image needs. In Photoshop, go Image -> Adjustments.
4. Sharpen: In Elements 5.0 found under Enhance -> Adjust Sharpness. In other versions of Elements, and Photoshop, it's Filter -> Sharpen .
5. Straighten: Elements 5.0 introduced the Straighten tool on the toolbar
. It may or may not give you the results you want. If it doesn't go, to Image -> Transform, try Free Transform, Skew, and Perspective. In Photoshop the transform tools are under Edit -> Transform, and Edit -> Free Transform.
