Prior to making a significant change to the layout I mocked it up using Photoshop.
Using the clone stamp tool I erased the tracks I was considering for removal to see how the changes would look before tearing into the actual work. Doing it this way saved me any possible regrets if I didn’t like the outcome. Knowing how things would look and thinking through the impact on future operations let me move ahead without the first tinge of remorse or second guessing.
I have Photoshop as part of Adobe’s Creative Suite 6 for my work (still pondering the implications of the never-ending subscription model Adobe has gone to). However, any photo-editing program worth its price should let you do similar work.
