We all know that all photographs that we see in magazines (those of models and famous people) have undergone some kind of retouching. But we don't always know how the original photo looked like. At website of Greg Apodaca in his portfolio we can see those "magical" transformations (don't forget to enable javascript). How could it help us? Well, if you look closely on what actually was done, you can try to attack those elements yourself in your photographs. So, you will know what has to be done.

The Internted is a field of scattered plants of information. Some of those plants are big as a tree, some are smaller and younger. I remember seeing Adobe Evangelists a few years back, so it means that they are not that young. And their content about Photoshop Tips and Tricks, Actions, Books and more proves that they are not small either.
As an example of the content you can check out their article "Blend Mode Magic".

While wandering in the vast seas of the Internet I found another island of information - "Photoshop Users Groups". As I understood it's a group of people interested in Photoshop, who at the meetings are discussing and exchanging information on various topics related to Photoshop. One of their pages (Tips & Techniques) holds a collection of good links to such resources as: BW Conversion, Camera RAW, DNG, HDR, Infrared, Keyboard Shortcuts, Lens Correction, and etc.
I recommend that you look at the other page called "Past Meetings", there you will find links to PDF documents about digital workflow, discussions about photo labs, and more interesting info.

Most of the time large corporations loose their person's face and become a huge lump of something impersonal. But there are thousands of people, who are affecting our lives in one way or another. Adobe Corporation is one of such giants that affect live of photographers around the world. How many people there do you know? Adobe Blogs is such a way to learn about those people and learn from them.
For instance, Jeff Tranberry has written several good posts on scripting in Photoshop. Scott Byer writes interesting stories about the underbelly of Photoshop and struggles it brings. Or read posts of one of the most prolific bloggers - John Nack.

We often resize objects to fit into a certain size. And such operation has a short cut - Ctrl-T (free transformation). But sometimes we need an additional tweak of the perspective. There is a separate menu item to do so: Edit, Transform, Perspective. This tool is useful, though most of the time something simpler would suffice. And that's a neat trick in Ctrl-T mode - while holding Ctrl key drag any of the corners to freely adjust the shape.
Note: You may drag the sides as well, and to lock the movement only to one of the directions hold Ctrl and Shift.
Extra: To ensure that your lines are straight in the picture (while adjusting perspective) press Ctrl-' to reveal the grid (press once more to hide it).
