Adobe Photoshop Tutorials

Here’s a very basic adobe photoshop 7 classroom tutorial which you need to know, cropping and resizing. This is all about image quality and why you should do it in photoshop and not on a camera.

Firstly it’s best to crop and resize at the raw stage, here you’ll find the difference may be quite subtle, but for images that rely on detail it can be significant. When you are using ACR crop and the straighten tools (Only in CS2) and also the size menu (CS and CS2) you’ll find you are working with the maximum available information.

Now let’s start cropping an image. To crop any image simple click and drag with the aid of the crop tool. It’s very easy to resize any image all you have to do is click the image and drag the corner handles. Here are a few moves you need to know. To move the crop box drag inside it, to rotate click and drag outside the crop box corners. Also to crop a aspect ratio, right click and choose a size from the menu which is n front of you. You‘ll find most times this is a very handy way to crop to standard print dimensions.

In addition to straightening a tilted image, the straightening tool crops the shot to the maximum possible size. Sometime you’ll find you will never be able to straighten some images, this is because the horizontal and vertical lines may not be right angles as a result of lens distortion.

Now when you have your image up in photoshop you’ll find to the bottom left of your screen a dialog box which will have a size menu in. This then becomes the crop size menu when you use the crop tool, this then sets the output resolution. Here you can see where the pixel dimensions and a guide to something called mega pixel size. Now from there you can shrink or expand the cropped area to get the resolution you want. Also ways make when you are doing anything like this to keep saving your image.
