I have a Rebel XTi. I am taking a 1GB and a 2GB memory card with me. I want to get as many pictures out of this as I can. What do you suggest I set my camera on. I know they have small, medium, and large. I also want to make sure I have good quality pics. Do I need to invest in another card before we leave?
I agree with the almost-consensus that you should buy
more memory cards, especially since memory is very cheap. I'd probably look into getting two 8-GB memory cards.
I also agree that you should take pictures in
large-fine JPEG. (even better would be to take pictures in RAW, but then you'd have to look into software to process & convert RAW photos into JPEG)
I figure, I bought my DSLR because I wanted the best-quality photos, especially compared to my old point-and-shoot cameras. So now that I have my DSLR for higher-quality photos, why compromise on quality by shooting
smaller JPEG sizes?
Also, if you want smaller JPEGs, you can always make them smaller later-on at home. Unfortunately, the reverse isn't true.
Someone suggested taking photos in "medium JPEG" until you have a special moment, and only then would you switch to "large JPEG". The only thing I'd caution about this strategy is that sometimes, you never know when that "special photo" will be. Let's say your child gets a kiss from Cinderella, and you've captured that moment beautifully...but accidentally in "medium JPEG".
Actually, I've crunched out the numbers, and here's what I found. Warning! Nerdy math ahead...
Ideally, when you print a photo, you want a resolution of 300 dpi (dots-per-inch). Slightly less (like 200-300 dpi) is probably okay, but ideally you want 300 dpi.
If you shot in medium JPEG, the size is 2,816 x 1,880 pixels. If you divide each number by 300 dpi, you get an ideal photo that's 9.4 x 6.3 inches (somewhat less than an 8x10 photo). This probably explains CleoPahd's experience in getting good 8x10 photos while shooting medium JPEG.
If you shot in large JPEG, the size is 3,888 x 2,592 pixels. If you divide each number by 300 dpi, you get an ideal photo that's 13 x 8.6 inches. This is a perfect resolution for an 8x10 photo, and it even gives you room to crop about 3 inches from the longer side.
Anyway, ultimately, I'd recommend large-fine JPEG, more memory cards, and larger-sized memory cards. Hope that helps.
