Figure 3 shows the effect of masking.

I used effects from the Grey’s Magic for Image Computing (G’MIC) add-on for GIMP, http://gmic.eu/
gimp.shtml; other high-end graphic processors have similar utilities. Figures 4 through 7 show the effects of
some of its filters.

Since the graphic will be used for a car
show, I’ve removed everything but the
cars and added some vignetting to soften
the sharp edges on the right. I’ve also du-
plicated the layer several times, so I can
try different processing on each one.
Masking is done by hand and is quite tedi-
ous, almost impossibly so with a mouse,
but far more tolerable with a graphics tab-
let. I use one by Wacom, which is small
(about six by eight inches) and available
for $70. Before duplicating the photo layer,
be sure you have completed the masking,
as you don’t want to repeat this time-
consuming process.
