Photoshop for the beginners

With Photoshop we can reduce the weight of the PSD up to 75%. This is something to think about, if we can reduce so much the information in a PSD it would be because this format is not very optimized, right? Most people think that's why there are files with compression, TIFF or JPG but they agree that keeping the original files in PSD format is much more comfortable than working with TIFF (i don't think we need to compare it with JPG). Well, how can we do this? Something as simple as hiding the layers before saving the file, if after that you compress it with Winrar or WinZip you will save a lot more. Here you have the information of the experiment: Normal PSD: 49,2 MB PSD saved with the hidden layers: 38,9 MB PSD saved with the hidden layers and zipped: 11,5 MB The new version of Photoshop CS3 is out and we still have the same problem we will have to wait a little more. Now, if you have to send a PSD via ftp or email you have no choice than doing this.

When you are creating a brush you can save and delete it, here is how: To Save Modified Brush Preset: After you make a modification to you brush shape or brush dynamic, you can save brush by do one of following using Brush Palette. Using Brush Palette Menu and select New Brush Preset. Click new button at bottom Brush Palette. If you use Small Thumbnail or Large Thumbnail you can click at empty area. To Delete Brush Preset. You can delete unwanted brush by do one of following option: Select brush you want to delete and select Brush Palette Menu and select Delete Brush. Select brush you want to delete and click Trash Button Select brush you want to delete Right Click or Control + Click and select Delete Brush.

Have you ever tried to make an image black and white? Did you use the desaturate method. Now if I go to Image>adjustments>desaturate and take away the color from the photo... I will be left with a black and white picture. But it doesn't look as good as it could. It seems dull and lacks depth. Here is a better way of making images black and white - Open up the picture you want to use. In the Layers palette go to the button circled in red in the picture below and then go to channel mixer in the drop down menu. Put in settings feel free to experiment. Now I am left with a much nicer black and white picture. You could even add a unsharpen mask (Filter>Sharpen>Unsharpen Mask). Much better that the desaturated image right?

Adding cool effects to photos is quite amusing. A fun one is to split apart a picture like a puzzle. First find an image of Guitar. Then open the saved picture in Photoshop. We are going to split the image. Go to Views>Rullers. Or simply press CTRL+R. Then using the Rectangular Marquee Tool. Press Ctrl+J to copy and paste the selected part in a new layer. Repeat these steps until all the parts of guitar is selected. Try drawing different rectangles because we want to add this puzzle effect. Select a layer and choose the blending options. Again apply the stroke effect as needed. Now right click the layer you applied the effects and select Copy layer style. Go to next layer and right click on the layer and choose paste layer style. Paste the layer style to remaining layers. Click Ctrl+T and transform each layer. With some Gradient Effect you can get a better effect.

Follow these instructions to add a contemporary frosted pixel overlay to your photos. Open a picture into Adobe Photoshop. Next, press Ctrl+J to duplicate the layer. Change the blending mode to Overlay. Go to Filter> Pixelate> Mosaic and in the Mosaic Photoshop filter settings, set the pixels to the size that you want the squares to be. Then, press Ctrl+J to duplicate the top layer and change the blending mode from Overlay to Multiply. Now go to Filter> Stylize> Find Edges. Press Ctrl+Shift+U to desaturate the outline so that they don't have any color to it. Go to Filter> Blur> Gaussian Blur and add a little gaussian blur to the outline which will add the frosty effect.
