In the current challenge, I have received several remarks concerning image distortion, which some reviewers have commented may have to do with re-sizing the image to conform with the website's submission guidelines and size restrictions. While I have absolutely no problems with the website's size restrictions (as the reasons for these restrictions are obvious to me...i.e. no knock on this wonderful website), I would like some guidance (or tutorial) on resizing images so that they do not look distorted in the end. I use PS and HP Imaging Software for post-editing work in case that is relevant. I thank those of you who might comment, in advance, for your input.

You first want to select your Rectangular Marqee Tool and at the top of your tool bar select Constrain Aspect Ration and enter either 640x480, 480x640 or simpler yet, put in 8x6 or 6x8 which is the same thing. Then select the area of your image that you want to crop. You will notice that the shape of your selection remains fixed. When you have your area selected go to Image/crop to crop the image. Next, go to Image/Image Size and enter 640 x 480 or 480x640 into the Pixel Dimensions making sure that Constrain Proportions and Resample Image with Bicubic are both selected at the bottom of the menu. This should do it. Make sure you save it as a seperate file from the original. Good luck.

I use the crop tool and check the box designating "Fixed Size," and then enter the desired dimensions. When you drag out the crop marquee it will maintain the proper aspect ratio, and after you execute the crop it will re-sample to the correct size at the same time.
The crop tool also lets you arbitrarily rotate the selection rectangle to allow for framing errors and slanting horizons...however rotation will typically degrade the image quality more than a straight re-sample operation, so be careful using it. |

Yeah, better yet, do it the way GeneralE said. I never used that Crop tool because there seemed to be something I didn't like about it but after using it just now it worked great and I couldn't remember what I didn't like about it. Go figure : ) There are probably a lot of thing that I am doing the long way but I will learn eventually. thanks for the better tip, Paul.

So that's one of the problems with my entry. Since I'm shooting a 1.3 Megapixel this time around I don't have much room for error pixel wise. I needed to do a rotate and it caused some "side effects". Thanks for the info GeneralE. I learn something new every day around here. . .

| I don't like using the crop tool - maybe because I'm just a control freak :) I tend to use the square marquee tool, with 'constrain to aspect ratio' set for 640x480 or 480x640 (I have presets for these so I don't hav to type it every time) Then I select the area I want and hit 'Image-Crop' |

Sheesh! I knew there had to be some sort of presets but I have been missing them all this time. Now my life is so much easier. And I thought I knew PS. Thanks Gordon.

You can save 'tool settings' for every tool that you use - in the 'options' tray under the little triangle. There are even loads of presets you can load up that way - particularly for brushes etc.

Actually you can use the presets for the Crop tool as well, for most tools for that matter, and you have a lot of control with it as well. And I was afraid I wasn't going to learn something new today.

Yeah I spent an entire afternoon when I first got PS7 and preloaded a bunch of custom brushes. It took a while to learn how to do it but it was sure worth it.

| a trick I use to do this is just make the small didimension 75% the size of the largest dimension... when you crop your height and the dimension is 1267 pixels then make the width 75% of that or 950 pixels... it's the same ratio as 640 by 480, then when you resize it won't distort on you..... |

| I think that means set the apect ratio (without units) to create a constrained crop at full resolution, and then resample later to the correct number of pixels. |
