Step 3

Change either the width to 1400 pixels or the height to 1050 (as in the example right).

Use Width 1400 pixels for a landscape format picture and 1050 pixels for portrait or 'square' pictures.

(Notice how the file size changes - in this example from 56mbs to just over 1mb.)

This stage puts a black border round the picture.

Use 'select all' (control A) then edit, stroke. In the example right a 3 pixel black border is chosen.
