Jerry. I never use the LCD screen, indeed, I would go as far as to say they are not really that useful.

Of course, there are times when the screen is helpful, i.e. when you are away from a computer for days or weeks on end. Having said that, the histograms that show whether something is under or over exposed can be useful.

I prefer to carry a decent amount of memory with me, keep the shots and then sort them out when I get home.

The only problem you do have is when not bracketing. Often there is only time for one shot and in those conditions a screen doesn’t help much after the event.

Other people do use screen, so I guess experience will tell you which way to go.

But, in summary — take as many shots as is possible and keep all of the results until you get home. I often keep even duff photos in my archive. I’m amazed at how often I find a use for them later on. Also, shots that don’t seem working on when they have first been taken often look more interesting a year later!
