Image Correction

Additional Resource Links:

Your goal is to make the image of your work represent it accurately. That means not too dark or light. Not distorted and at the correct size and resolution appropriate for display on the website.

Final image size for display on screen should be 100 ppi with 10 inches the largest dimension. In Photoshop, make this new size from the top menu>>Image>>Image Size>>type in desired dimensions. Resize

As you can see from this sample picture it is not suitable for presentation of any kind as it currently is. It needs to be visual edited;

  • the image is too dark (lack of dynamic range)
  • details do not have enough definition
  • it is not squared up to the borders (keystone effect)
  • and it is not cropped well


To correct these distracting errors you must open your image in PhotoShop before placing it in your portfolio.

The steps to correct these errors may be completed in any order, but are as follows:


  1. Open File in PhotoShop
  2. Select all (command + A keys)
  3. From the Menu bar at the top of the window, select “Image” then “Adjustments” then “Levels


4. Then adjust the pointers under the Levels Preview window so that they are only under the part of the Levels histogram (the black graph) that shows information in black “mountain”shapes. In the example below, that means moving the left or black pointer slightly to the right and the right or white pointer to the left until it is directly beneath the black line which indicates the beginning of the histogram.

5. Hit the OK button and the dynamic range of your image should be vastly improved. Further tweaking of these sliders may further improve this aspect of the image.

6. Alternative to adjusting the dynamic range using Levels, you might simply select Auto Contrast and Auto Tone found under Image in the menu Bar. This option is usually helpful but is more generic or average than using Levels.


  1. Select all (command + A keys) if it is not still selected after the previous step.
  2. From the Menu bar at the top of the window, select “Edit” then “Transform” then “Distort”.
  3. Pull on the corner handles to straighten out the image.
  4. Double click anywhere inside the selected area to accept your adjustments
  5. Save

  1. From the Tool bar or menu select the cropping tool.
  2. Adjust any of the handles at the corners or middle of sides (or alternatively use the cropping tool and drag a box around the image you wish to keep) to crop or delete the excess unwanted background part of the image leaving just the artwork.
  3. Double click anywhere inside the selected area to accept your adjustments.
  4. Save
