Learning about editing digital photography

Color Correction: You can change the color of your image and balance the overall exposure of your images in a number of ways. The most common is by using the levels function or the curves. Here you can gently touch up your photo making the dark areas darker and the lighter areas lighter to achieve greater or lesser contrast. There are countless other methods and techniques you can use with Photoshop to better your images without having them look like they have been altered. Selective blurring can give the impression of movement, you can change certain areas of a photo such as the color of a specific object, red eye effects can be removed, skin blemishes and spots can be hidden and even with a little more skill and knowledge, complete makeovers can be achieved. We have an ever increasing collection of video tutorials on our Photography Book web site which show you step by step how to achieve some of these process.

With Picture Manager you can work with multiple pictures at once or edit pictures one at a time. You edit pictures in the Edit Pictures task pane. The quickest and easiest way to clean up all your pictures at once is to simply select them all in the Edit Pictures task pane, and then, on the Picture menu, click AutoCorrect.

Creating Double Exposure effect: A double exposure image is created by overlaying two images on one another. Follow a stepwise procedure: 1 Select all or a part of the image using the selection tools at the top of the toolbar. 2 Now from the edit menu choose copy. 3 Now open a second image file. 4 From the window menu, you can select the show layer. 5 On the ’show layer’ popup right click and choose new layer and press ok. 6 Now go to the edit menu and press paste. 7 From the layer’s palette, move the opacity slider to 50%. 8 Now drag the mouse from inside the selection to move it. 9 To scale the pasted selection, click on image menu and then select image size. Adjust the size by adjusting the pixels and height from the pop-up window.

Photoshop costs around $600 these days, and Gimp is free, so of course if cost is a factor you’re going to swerve towards Gimp. Photoshop has two leads over Gimp: patented features the interface that everyone is used to Most especially, Gimp is out of the running for professional print shop editing, thanks to the patent lock on industrial features such as color correction and CMYK. Gimp can emulate these features with work-arounds, that’s all there is to it.

Adobe’s Photoshop software is a very powerful image editing program that is by far the market leader for editing image files. I use Photoshop extensively when creating, and editing images for the web sites that I design. Almost all professional photographers and printers also use Photoshop to create all of the wonderful images that appear in magazines, billboards, and even on television. I am not the best artist in the world, but with Photoshop I have enough power to create brilliant images with tools that are built-in to the software.

The basic idea is to either copy the Background Layer and make any adjustment directly to it (color adjustments, sharpening, bluring, contrast, exposure, etc.) or make that alteration in an adjustment layer. Once you’ve made the adjusted layer (either using a duplicated layer or a true adjustment layer) then Go Overboard!! I mean it, allow yourself to go way sharp, way blurry, way magenta, way saturated, whatever you’re doing, do it more than needed.

When I am creating web sites I use Photoshop to create the navigation for the web site and also to optimize all of the images, so that my web site will load faster. I usually create buttons for the navigation, and then create rollover effects from within Image Ready. This saves me quite a bit of time, because all of the JavaScript for the mouse over effects are done for me, which allows me to work on the more advanced coding of the pages. Even if you want to create all of the navigation and layout of your web site without Photoshop, then you should at least use Photoshop to optimize your images so that you web site loads within a reasonable amount of time.
