Looks like a pleasurable challenge!!
One hopefully helpful hint about photos that's worked for me for MANY years....IF you can try taking photos on a cloudy day you'll get good light and a lot more detail throughout the target/slingshot, etc. and it helps eliminate shadow problems - Also using a properly placed white board or boards, piece of paper, etc. around and out of frame can help lessen the shadows if that's a problem - Because I used to be in a business where photos were very important I always have on hand a piece of white, black and medium gray cloth for backgrounds...old sheets, t-shirts, towels, etc. - You can pick pieces fairly cheap at any fabric/craft store etc. - When choosing something other than fabric it also helps to have that background item on the dull or satin side so as not to cause more reflections, hot spots and shadow problems - I see a LOT of photos where the background disrupts the main subject or slingshot that is the main purpose of the photo - Just one more.... it usually helps to have something in the photo that can give the viewer an idea of the actual size of slingshot, etc. of main object of the photo such as a ruler, coins, $100.00 bills, etc. - One man's to big is another persons to small - Hope some of these help - Feel free to ignore my rambling :hmm:
