Step by step guide of the creation of the logos

This is a 5 step guide on how I created the Logos for my Radio stations. All the logos were made in a identical way in this case we are looking at the shred logo. I started by creating a new transparent lay out for psd. 20cm long and 30cm high. With this canvas I used a circle tool for the first layer as seen in image 1. To keep the circle in the correct shape I dragged out the circle while holding down shift.I then set the colour for the new layer as black using the colour selector at the top of photo shop. I then created a second layer using the circle tool that was smaller than the first layer. To keep the proportions the same as the first layer I used the Shift+drag to create the desired shape. After I did this I moved the shape into position over the first circle to create the effect of the border.In image 2 you can see I then changed the layer colour to a deep red to contribute to a violent rock look. One of the things I noticed during the creation of these idents was the border size between the two circles was not consistent. Sometimes this distance was far different that the others because I could not make them visually similar. I then decided I would create the two layers once and save them three times. I then pallet swapped these files for the other idents this stopped the problem of the different size borders.
