Hi Don,
You're in with a chance, then, if you have a right to roam. ( I take it when you say 'you will give them one, you mean to give them a print, not like my mum used to say to me, 'if you don't behave, I'll end up giving you one' (meaning a clip round the ear))
Get in there with your lens and camera, get up close take just a few leaves, look how they are arranged, take some full frame trees, or get back for wider views, leaves on the ground - pattern, colour, bare stark branches, all the usual stuff. Look how trees work. Take at least a few hundred shots, at different times of the day, if you can. But think about what you are trying to achieve with each shot, for a second or two, before you press the button. If you think moving a foot or so to the right would have been better, do that, take a couple more. The first thing is composition, although cropping can take place in some instances, you'd have to be pretty cute to get the angle of the fence line changed in post processing. If the fence is of interest, a few dozen more shots. Try different apertures, speed's, iso's, whatever. Shoot in raw. Next day, whenever, whizz through looking in picasso, or whatever, note down the few that instantly look nice. Maybe the same a few days later. Get it down to two or three. If the colour is crap, try your pp skills, post it here, someone will give precise details on how to rescue it. If it can't be rescued, there's always next year. Digital images cost you nothing, just your time. A month or so later, you will probably pick different images from your collection.
Get up before dawn, sieze the day ....
Maybe, that just about sums up my knowledge of it all....
Best wishes,
Ray
