Resizing Images



It seems that resizing pictures to comply with the rules is giving some of us a bit of problems. Here's how you do it.


Resizing for CTF Challenge



The first recommendation is to crop first and resize second before you do anything else. The sharpening and other effects look better after an image has been resized.



The second recommendation is to limit the longer side to 800 pixels or less. Remember, the smaller your image is the easier it is to get it under 150k. Unless you have a compelling reason to make your picture over 800 pixels, just don't do it.



The third recommendation is ignor DPI (dots per inch). DPI is significant only when you are printing an image. When you are viewing it on pbase.com it is the pixel dimension that counts.




Photoshop CS:

  • Open your picture.
  • Go the "Image" menu
  • Select "Image Size..." A dialog window will popup. It shows the width and height of the current picture. They are "linked" to each other, so if you change one, the other will change automatically.
  • Make a decision of the visible size you want. For a horizontal picture, 800 wide is a very nice size for most current screens. For a vertical, you can use say 650.
  • Now, put only the measure you want to change(be sure to select "pixels" as the unit). The other will change itself. And press OK.
  • Save the image using "Save as..." with another name, so the original stays as it was. Use tif or psd to take advantage of layers.
  • You can now do whatever you want to the image, like sharpening, color balancing, etc.
  • Once you finish, use again "Save as..." and choose jpg. A dialog will popup to ask where do you want to save it and when you do that another dialog will popup asking the quality. You can choose from 1 to 12. Usually, from 5 to 10 will create picture less than 150kb. In the lower part of that dialog, you will see the size in "k" for the resulting picture.
  • Done



Photoshop Elements 1.0 and 2.0


  • Open your image
  • Go to the "Image" menu
  • Choose "Resize". A submenu will open.
  • Select "Image Size..." A dialog window will popup. It shows the width and height of the current picture. They are "linked" to each other, so if you change one, the other will change automatically.
  • Make a decision of the visible size you want. For a horizontal picture, 800 wide is a very nice size for most current screens. For a vertical, you can use say 650.
