If you have a particular problem with your work, then look for a solution to that problem. And *IF* the solution looks like it might be a gray card, then by all means get a gray card and start learning to use it.

But do not get a solution and then start looking for a problem in your work to solve with that solution.

That isn't to say that a gray card may not be just the thing you need. But you haven't said why you think you need a gray card, and now all these old guys like me are making jokes about it.

But again, don't fall in the trap of seizing a solution then trying to find a problem to fit it. First try to identify what area you need/want to improve, then look for the tool to do that. And if coming to understand and utilize a gray card for critical exposure control is part of that solution, then jump all over the gray card.

But a gray card is not a magic wand. Don't dismiss it, but don't put too much value in it either.

Hmm well it's a relief to know the 'old guys' haven't put much effort into grey cards over the years either from the sounds of it! I really thought I would be shamed and pointed at like a loser confessing that I don't have one

But anyway, I think I need to use a grey card for a kind of ball of yarn reason: when I shoot on 4x5 film, I always seem to screw up my exposures, and now that I will be basically forced to print negs digitally (graduated from Honours, no more free equipment access) I want to make sure I am exposing better, and able to use the grey card as a device for colour balancing in Photoshop once I've scanned.
So I guess I am wanting to be more controlled with my precious exposures and make sure the colours are able to be balanced correctly after scanning, and I figure if I start getting to know grey cards better, I can improve on both those levels?
