Get some cool Photoshops
nt to get rid of that nasty shine that you get taking pictures? Well now you can, follow these easy steps: Let's start with a great, overlooked trick. After opening the image, open the same image again in a new window. In Photoshop, choose Window ->Arrange -> New Window. In Elements choose View->New Window. This allows you to view one window zoomed in for detail work and the other window at 100% so you can judge the effects. Using the magnifying glass tool draw a box around the area of shine. Make the box big enough to also show a fair amount of un-shiny skin. Select the Clone tool. At the top of the page select Mode: Darken and use the slider to set Opacity at 50%.Using the Clone Tool, select an area of un-shiny skin by putting the circle over the area and holding down the Alt button while left-clicking the mouse. To best match skin tone try to select the area of skin closest to the shine. Quick tip, to easily resize the Clone Tool circle simply use the bracket keys, [ and ] - much easier than moving your cursor back and forth between the photo and the Size slider. Now simply click on the shiny area and watch the magic happen. You'll have to experiment a little for best effect, and for larger areas be sure to resample the un-shiny skin frequently. In the zoomed-in image the effect might look too obvious, so you'll need to keep an eye on the 100% image to track your progress. Notice the difference on the tip of the nose, the cheek, and above his eye.Pictures are made up of many things, editing requires knowledge of all 3: 1) Contrasts adjustments (the highlights and the shadows) 2) Neutral tones balance (color cast on grey) 3) Increasing or decreasing the saturation The work flow of the photographic post production can be performed with many adjustment tools as: Brightness/contrast - Color Balance - Hue/Saturation, or Levels - Hue/Saturation, or Auto-Adjustments - Sponge. This tutorial is very brief and introduces a new method to decrease color cast on neutral tones. The picture has a really intense orange color cast. I took this picture of Christopher Columbus' statue along the "lower pavement" in Funchal (Madeira Island). No need to be a colorimetric expert to understand that, the light effect due to the night orange lights is to much. The goal is to decrease color cast, of course, without changing the "meaning" of the picture.First of all we duplicate the background layer. Then we apply Filter>Blur>Average, that will transform the picture's layer into a colored "stain" by the average pixels' color. Then we have to invert (ctrl+i) the obtained color in order to see the opposite color.Now we change blending mode to Color (read also Blending modes tutorial) and decrease master opacity until we obtain our goal. And that's all!Brightness/Contrast is a super important technique in photo manipulation. You can alter the complete mood of photos with brightness and contrast. I will demonstrate how. First get a picture of anything in the world you want. ANYTHING! Now go to Image> Apply Image and apply your image on a new layer. Then go to Image> Adjustments> Brightness/Contrast. Then mess around with the settings. I tend to make the lower the brightness and raise the contrast. But see what is best for your picture. After applying Brightness/Contrast/ Do you see the changes? I sure do. I completely changed the mood of the picture with Brightness/Contrast. So as you can tell this is a very important and helpful piece of Photo manipulation.Open the JavaScript Reference Guide and click the ArtLayer bookmark to the left in Adobe Reader, now you can first se all properties available for ordinary layers and after that is all the methods available for it. Hello worldNow it's time to try your wings by creating and running your first script for Photoshop. As always the first program you create in a new programming language should always output the Hello world sentence. To install a script you simply copy it to Photoshop's scripts folder which in windows is located in: c:Program FilesAdobePhotoshop CS2PresetsScripts Before you can use it from Photoshop you have to quit Photoshop and restart it. Once you have done this the script is available under File > ScriptsStart 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 texturised background if you wish.Layers are an integral element of Photoshop. They allow you to edit images more easily, and use transparency to its full effect. By default the background layer (Locked and labelled "Background") is white, and any subsequently created layers are transparent by default. Layer Opacity: The opacity of the current layer, 0-100%. Blending Mode: The manner in which this layer interacts with layers below it. See below. Active/Linked Layers: A small paint brush icon appears in this space to indicate the active layer, and chain icons signify other layers that are linked with the active layer. Layer visibility: An eye in this area signifies that the layer is visible, and an empty box means it is hidden from view and exempt from formatting. Layers: Two example layers showing an example background layer and new (transparent) layer (Layer 1). New Fill/Adjustment Layer: Creates a layer that can add a gradient to or adjust the hue, etc. of the layer below. New Layer: Creates a new layer [ctrl/cmd + shift + N]. Delete Layer: Deletes the currently selected layer. New Layer Set: Creates a folder for layers to be put into for easy organisation of layers. New Layer Mask: Creates a sub-layer with which you can use all normal tools. Adding black to a layer mask, for example, means that that part of the layer is invisible. Layer Effects (Styles): Applies various effects to the current layer - can also be reached via.A way to make a whole pallette from the three colors is not extremely difficult. Open a new canvas, does not really matter the size, but keep it no smaller than 468x60. Click on the gradiant tool on the left tool bar. Go into the Gradient Editor, by clicking on the colored gradient on the top toolbar. Place the darkest of the three colors on one side, the lightest on the other, and the midtone in the middle. Keep the opacity at 100%. Press Ok, then click-drag a horizontal line across the canvas. You can use the eyedrop tool to take the color from this canvas and color the skin of your project. Now that we have a pallete of color, we have to understand the effects of lighting on skin. It's a very simple concept, but understanding it is necessart to shading skin. As any matter, the brighter the light, the lighter the highlight and the darker the shadow. The dimmer the light, the difference between the light and the shadow decreases. The shadow cast by it is also affected by the light and darkness. The color of light affects it in the same way. If the light is green, it will have a green tint to the skin. If it is a small light, such as a lamp, a smaller portion of the skin will be that color, instead of affecting the whole skin. As stated before, most matter is affected the same way as this.
