That is one school of thought.
Personally I take every pic with my camera set as high as it will go, 4000x3000 for mine. The more pixels you can capture the better.
Then I just let the paint program do the work.
In my case I have been using the free fully functioning non-expiring version version 4.12 of Paint Shop Pro for over a decade for all my picture work.
I have the program for free download and a fully illustrated tutorial of how to take and post really great motorized bike pics here.

I figure if you want to show off your work you might as well put as much detail in your pic as you did your bike, and you must admit I make pretty good pics just using PSP.
Then again it helps to have an instant 'photo wall' and good light too ;-}
That mirror is movable and my big glass shop door faces West so I get great natural light there in the afternoon.
Regardless of the program you use you may find my Tutorial on how I take and make pics for forums helpful.
