  • All about how to use you digital camera
    There are certain features on modern digital cameras that you can live without. Two closely related features in that category are digital zoom and interpolated resolution. Both rely on the same principle, and it is definitely something better left to the editing software on your computer. When on the subject of digital cameras, interpolation is just a term for a computer's best guess as to what should happen when you try to turn one large pixel into more than one smaller pixels. The computer (whether it's your home PC, a dedicated graphics machine at a photo lab, or the chip in your camera) uses mathematical formulas that try to guess, based on the colors of surrounding pixels, what the new substitute pixels should look like. For example, if a series of black pixels in a line on a white background are doubled, the pixels added between the black pixels will be black, and those between the white pixels will be white.
  • When you want to learn photoshop who do you turn to?
    With the spot healing tool, you simply click on or drag across the flaw you want to remove and it disappears. The retouched area is blended into the surroundings seamlessly - most of the time anyway. It takes a little practice getting a feel for how brush size and healing work together, but most of the time it does an impressive job.
  • Having information on photoshop can come in handy...
    There are only two things you have too know about the ExtendScript Toolkit program right now: Select target application, ExtendScript must know which application you are writing the script for. In the top left dropdown menu select Adobe Photoshop CS2 and if asked if you want top start it choose yes. Running script, to run a script you have written you press the button that looks like a play button. Reference documents All objects have different properties that can be set and methods that can be executed and right now you probably don't know any of these, this is where the reference documents come in. The reference document for JavaScript contains information about all objects available in your scripts. Start with a blank photoshop document of size 1024*768 and white background. Choose the brush "rough round bristle" from the toolbar. Create a new layer and draw some lines. Right click on the new layer and choose "blending options". Choose the values. DROP SHADOW INNER GLOW BEVEL AND EMBOSS; For "texture", choose "satin" as the pattern. TEXTURE Now add some motion blur to this layer from filters > blur > motion blur. Similarly, add gaussian blur also to this layer with the radius around 72. Not so catchy yet. Well try this. Change the background color of the default layer as black by choosing Edit > Fill from menu. Now look at the output. Ahh, that looks much better, isn't it ? You can add some text to this texturized background if you wish.
  • Photoshop is vital to your digital photography
    The next in line is a list of four tools that provide ways for the user to fix problems in images. The Spot Healing Brush tool first appeared in Adobe Elements 3. It was implemented into Adobe Photoshop CS2 after that. This tool allows you to fix areas of an image by replacing or blending the colors in an area so that it is like growing a new piece of skin over a bad rash. The Healing Brush tool allows you to fix problems in the image by sampling the surrounding area around the problem and trying to replicate the pattern in the area that is problematic. The patch tool is pretty much a mix of the Healing Brush and the Lasso tool. It is allows you to highlight the area that is scratched or empty and sample the surrounding area to fix the problem. Lastly, the Redeye tool allows you to select the common problem of red eyes and correct them with sampling a piece of the black pupil area and replacing the red eye with the natural pupil color. This is a widely used tool by many consumers.
  • Start editing your photos with photoshop, learning just got easy
    It is this photography 'purest' to whom I appeal (this time) - the ones that still like using film every now and then. Most photographers have Digital SLRs (DSLR - "et moi aussi"). I know you can create this effect with Photoshop, after the fact; but having creative control over this special effect makes it exciting because you execute this photo miracle at the precise moment you push the shutter button. Ghosting. This is what this special effect is called; accomplished by using your SLR's multiple exposure feature, but with a simple twist to ensure proper film exposure. The procedure detailed in this article is different from the instructions in your SLR manual.
