P mode allows you to make many more setting changes but still controls the shutter and aperture. Auto pretty much takes over the camera.

Amfoto1, Bravo. No sarcasm, since some of us are shooters not teachers. It's not easy to explain the subject in concise terms that non-photographers can grasp. Having read so many queries of this nature, ie, whats 'A', whats 'P', whats 'M', it's good of you to put it succinctly. That anyone who purchases a DSLR can't be bothered to download and actually read the manufacturer's manual, yet can post in internet forums, is interesting, but another topic. Along with automobiles that cost thousands and come with manuals that no one bothers to read, this sort of question is bound to crop up. It's difficult to grasp why anyone purchasing a DSLR, wouldn't bother to download and read the manual provided, but it's not difficult to believe trolls wouldn't bother post questions such as, what 'A' 'P' or 'Tv' means, and so many times results in answers, "Auto, Professional or Cable."
In the past, Nikon nor other manufacturers bothered providing detailed manuals until digital media made it inexpensive. They did have marketing departments with great photos clearly showing the top, front and back of the cameras. A surgeon buddy once asked my advice, what the letters on the dial meant. He said it was a gift for his daughter (he was into Polaroids so it was a big thing). Since I'd shot his daughter's wedding, it was a mutual appreciation event. When the FE/FE2/FA arrived, dealers sometimes had brochures in the rack, but no one had a manual in those days. Buyers either knew how to use a camera or paid for courses, and no one ever volunteered good information, which didn't involve an exchange of funds. There was no internet and no forums to ask. Cameras/lenses were just as expensive then as now, given inflation A good deal of effort is put into manuals, yet the manufacturers can be a bit obtuse at times, or don't explain the systems well enough that those starting out can get a handle on operations. Some of the double-speak in the manuals confuses even the old hands. Providing a good, easily understood answer as you and others have done should be appreciated. sv.

P=Program, as others said it allows some auto setting constraints. Some cameras also have one or more Custom modes (C1, C2, etc.) that allow you to set up custom settings. Personally I only use M, Av, Tv, X.

). They're just kidding themselves though, because they aren't really shooting manual at all.... they are just using a relatively new form of auto exposure. (Further.... I'd never combine Auto ISO with P, Av/A or Tv/S... because with Auto ISO any of those would become a rather unpredictable "double AE" mode... and I really can't think of any situation where such a combo might be purposeful and helpful). Excellent finally!
My prospective is that P, Av or Tv modes with fixed ISO are the same except 1) in P mode the camera selects an A and T pair which provides the correct exposure based on the other settings of the camera like ISO and exposure compensation but the user can change the pair selected by another manual control on the camera or alternatively can increase or decrease the ISO which in turn will cause the camera to change both the A and T in directions to correct the exposure which are of course different then just selecting a different pair to maintain the exposure for a set ISO, 2) the Av mode is the same expect the user selects the aperture and the camera sets the speed (or shutter Time) for the correct exposure which can be further controlled by setting the ISO and 3) the Tv mode works like the Av mode except the user sets the shutter speed instead of the aperture. In my experience the Av mode followed by the Tv mode are the most useful and most used modes by those, including myself, when they don't use the A or M settings.
As noted in previous posts other settings like forced flash are only available in these three modes plus the manual mode.
Their value is that even though they can be used an a very similar manner as the manual mode to set both A and T (but don't have to be), shifts in the light, especially in an outdoor environment are automatically compensated by both A and T shifts in the P mode and either the A or T shifts in the other two modes.
This was a very difficult expanded explanation to write, I hope it was useful to some.

I use all the settings: P, A, S, M, Movie, C1, C2, C3, Art, iA, and iA+. Panasonic GH4...
iA+ is very useful when recording raw images in run and gun situations. It allows lots of control while automating the essentials.

On mine (Pentax DSLRs) Auto mode is fully auto -- all decisions by the camera -- while in P mode, the camera selects shutter and aperture, but leaves other controls to the photog. (The way Aperture priority leaves Aperture size to the photog and Shutter priority leaves shutter speed control to the photog.)
