Skills Development: Construction - Photo Shop

I made my lightning bolts and explosion graphics on Photo Shop which were based on my scanned in, hand drawn sketches. On both of the original sketches, I used the 'magic wand' tool to take away the white background which left me with just the drawing which I wanted to use.  I then used the 'polygon lasso' tool to cut away at the edges to make sure that they were all completely straight edged. After this, I used the 'paint bucket' tool to change the colours of my graphics. For my explosions I just used black and white but for my lighting bolts I used the 'colour picker ' tool to make sure I had the exact same colours I used on my masthead.
