Hello all, I know this might sound trivial and simple but I want to know if there is a best way to do this. My friend got married a couple months ago, finally her pictures are uploaded except for her wedding invitation, the original pic is low resolution, she has asked me to see if I can take a good, unblurred, picture of her wedding invitation, this will go on the front page of the photo album.
she doesn't want any flowers, no decorations around the invitation, just the invitation. any suggestions?
This sounds like she wants a flat / square image of the invitation -- the invitation would "fill the frame" so you can't see anything in the image except the invitation. If the invitation is not filling the frame, then you'll need something to frame it -- flowers are great, but she says she doesn't want that... fabrics can work as well.
If you do plan to fill the frame, you'll need even light from the sides... a light from behind (such as an on-camera flash) will create a reflection/glare. Think of the invitation surface as if it were a "mirror" (surfaces do not necessarily have to be glossy to create a reflection or glare.)
Getting the camera close enough so that the invitation can "fill the frame" will be a problem.
Your profile says you own (among other things) a 5D II with a 24-70mm f/2.8L lens. That lens has a "macro" range. It's not "true" macro (not a 1:1 scale macro) but it will get close enough to fill the frame of an invitation. Set the focal length to the 70mm end. It may help to use a tripod when doing this because it's important that the invitation surface be absolutely parallel to the sensor on the camera. If the camera or invitation are tilted -- even just slightly -- then while it may be tack sharp in one area, you'll find it falling out of focus in at some edge because the depth of field is extremely narrow when shooting close-up subjects (and this is even true of fairly high f-stops.)
