BEFORE WORKING ON AN IMAGE ALWAYS DUPLCATE IT

• Go to Image/ Duplicate
• Close the original image, it then cannot be damaged or lost.

•  Choose CROP tool
• Drag marquee over portion of the image that you want to keep
• You can change the marquee by dragging on arrows on the side 
  and the top and bottom of the marquee.
• Press ENTER or DOUBLE CLICK inside the marquee.
• TIP****    To CANCEL right click and click CANCEL or PRESS ESC.

• Open Image
• Image/ Adjust/ Levels.
• Move left hand arrow to start of dark mounds.
• Move right hand arrow to right side to start of dark mounds.
• Do not move the centre arrow, we will use curves to adjust.
• Press OK.

• Firstly go to Image/ Adjust/ Threshold
• Move the arrow to the left hand side and note the darkest spot.(In your head)
• Move the arrow to the right hand side and select the lightest spot.(In your head)
• PRESS CANCEL!!!
• Go to Image/ Adjust/ Curves
• While holding down CONTROL AND ALT - click the mouse on
• the darkest point on the image, then move over image and click on the lightest point.
• Using the arrow keys on your keyboard, move the UP key to lighten and
• The DOWN key to darken.
• Select OK.

• Image/ Adjust/ Saturation
• Move arrow on the Saturation Line SLIGHTLY until you feel the colour is satisfactory, if
• you saturate the image too much it can look really artificial.

• Always resize the image after you have finished working on it. If you resize first the file will be too big, and the computer will takemore time, a much slower way to work.
• Go to Image/ Image Size
• Make sure you click the Constrain Proportions box and the Box below also
• At this stage do not take any notice of the Pixels size boxes
• Alter your size -   height and width (either in inches or cms)eg. 10” x 8”, you will find the size adjusts in proportion.
• Change the DPI to 300 if printing up to A4 400 if larger.
• If the image is approx 10” x 8” or (200cmsx250cms) the size of the file should be about 30 to 40mg

 

 

TO APPLY THE "UNSHARP MASK" FILTER

• Filter Menu/ Sharpen/ Unsharp Mask
• AMOUNT -  Use low setting ..  50 for people or natural objects, higher if the image contains sharp edged objects (the larger the image the less sharpening may be required)  For a high resolution image use an amount between 250% to 200%
• RADIUS - Cosider the final size, the resolution, and the subject matter.  Suggest using  1.0 a higher value could produce too much contrast in areas that have a high contrast.
• THRESHOLD - At 0, filter will be applied to the whole image, to prevent noise from distorting skin tones use 8.
