I've been using Photoshop for about 15 years. I owned version 2.5, at a time when the Windows and Mac
versions still had quite a few differences. I took PS lessons long before it was a common thing to do, at $60 an hour.
(After I finished writing my post, I came back to the top to qualify my comments. I'm not trying to flame anyone. No reason
to be rude. However, I've spent a great deal of time and money learning PS from experts. You can perform miracles with PS.
Generally, people who are that good with it are not messing with something like 141.)
The demo that's posted makes it look incredibly simple, but it's not. It's easy for that person because he/she is an expert.
The strokes are anything but random. The operator knows "exactly" what's needed.That's only one photo though. To go
manipulate a set of 8 different, but similar photos of the same person to come out almost identically is 1,000 times more difficult.
As for girls' heads looking out of proportion at times, that doesn't have to be caused by Photoshop. More
likely, it's related to the focal length of the lens or lenses used in combination with the varied distances
between the model and photographer. That's a very common mistake in model photography. Those
usually get left on the cutting floor.
The lighting issue goes back to the photographer as well. In a hotel room, there's light being reflected off of
the walls, floors and ceilings. However, it's also reflected off of the other person or persons walking around in
the room, not to mention light and dark furniture and sheets. That "interference" can lighten or darken areas
of the model. Also, the camera angle varies dramatically through a typical shoot. A good photographer is going
to be on his knees at times, scrunched up against a corner, standing on a stool, etc. All of those things result
in variable lighting. Heck, he may have a silver reflector on the floor, which is very common, but at some point
he moves it away. It makes a big difference.
What's being claimed is of course possible. The question is: why? If they're going to fake us out, just start by
using fake photos. Practically every published photo of a woman these days is adjusted to blow out the
blemishes, but that only takes a few minutes. In a typical BKK mall's photo kiosk, the computer is already to set
to do that. It requires no PS expertise whatsoever. I honestly don't think the PS tricks done on 141 go much
past that.
