I understand that it can be a little daunting, and perhaps I should have been a little open minded when giving my advice.
I was mainly speaking from personal experience.
When I first got into photography, I had no idea what aperture, shutter and ISO were. I had never ever even had a P&S. My first camera was a fujifilm s5500 which is an SLR-like P&S with a manual mode.
I'm a tech head so threw it into manual, without knowing what things do, and for me, atleast i pretty quickly learnt that adjusting the knob on the top (which controlled the shutter speed only, although I didn't know this) made the pictures brighter or darker.
This then made me read the manual to figure out what it was.
I then realised you could adjust aperture too, though at that time, It wasn't about depth of field, aperture was just another mechanic to make the picture brighter or darker.
Then you just play and play.
I understand it's going to be a bit confusing, but, I mean, you don't buy an SLR without any camera experience at all. Furthermore, if you are interested in photography ENOUGH to spend the money on an SLR, you didn't buy it to stay in Auto mode whilst you figure things out.
By your measurements, he wouldn't know what shutter speed is, or aperture is to even know what the camera is doing whilst in those priority modes. Just as my advice, for a total newbie, it will just be a case of brighter or darker, or a few shots being out of focus due to DOF issues, and no idea how to fix it.
Maybe i'm overshooting the mark here, but if it's taking 4 hours of manual mode to even get a decent exposure, then perhaps it shouldn't be case of going back to priority modes, but reading the manual.
Sorry if my post seemed a bit narky, or overbearing, but I'm a big advocate of throwing yourself in the deep end. If you spent the money on an SLR you're not going to give up after 4 hours, even without any good photos. You buy an SLR because you want to master the settings, and for me, going in the auto mode isn't the reason why I purchased an SLR for the first time, or anyone I know who purchased an SLR.
But then again, i'm not everyone, so I apologise if my advice is not very universal. It worked for me, so it was the advice I gave.
Although it may not work for everyone. But then again, that is the reason why everyone can post, to give different points of view.
