This is so fascinating!

So many of you have really provided some great, easy-to-digest explanations.

This is really making me looking forward to someday having the money to get a better camera. It's too bad that Canon doesn't make a camera similar to it's Rebel, but 2/3rds the size. Much more manageable for a midget like me with tiny hands.

I'm planning on looking into that when I start next semester. Unfortunately, the photography classes I want to take require a manual camera- after much looking, nobody has one I can borrow or afford. Maybe next year!

In my little Canon Powershot's defense, I do get compliments on the pictures it takes- most people are surprised that it's not from a bigger camera. I think it's a great camera in a small package.

it is a good camera when it comes to point and shoot. but once you save up enough to upgrade, you will be soo happy with the things to can do

[Izzie]

I agree, I'll be stoked when I can upgrade. But just going from the Nikon to this Canon was like a new lease on life. I can adjust a large number of settings in the manual mode (much as I can do with a Rebel), and it's macro settings are perfect for what I do.

yeah. i had that one before i got my nikon d90. the reason i went with the nikon, was because i could use my old lenses from my film dadys on it. you cant do that with cannon

Great explanation, just missed the mention of "density above base fog"

But as a large format sheet film shooter (also 5DmkII), I must protest re the above. Those chromes on the light table, and there is a big smile on my face. Placing that focal plane just where I want it with swing and tilt, adjust proportion with movements of the back standard; there's nothing like it. Sure, it takes between 15-45 minutest to set up a shot, you have to use an external light meter (Sekonic 558L), add bellows factor, and do color filtration after metering color temperature with a Minolta Colormeter III. Printing one of those bad boys (~550 MB 16bit RGB scan) at 13 inches wide (Epson R1800), I see the difference to the 5DmkII + Zeiss glass RAWs, the Arca 4x5"s winning clearly. The only thing that beats that, would be a 8x10"; still tempted ...

And, no, I'm not retired yet, not by a long shot. I freely admit, I'm off by several standard deviations from the norm. LF is not for everybody, but if anybody wants to go the distance, it's a great hobby.

This is not entirely true - it depends on what lenses you had before making the switch - I was able to use my lenses from the Canon Digital Rebel (film) on my EOS 350D, and can use them on my 7D as well. That was the reason I went with Canon digital - I didn't have to buy all new lenses.

[ronaldhanko]

I agree with Tropterrarium - the old days of film were not all bad. I still miss my film camera, though I doubt I would go back - digital is too convenient. I miss the sharpness, the color saturation, the carefulness required in shooting film.

I love technology sometimes. This is so fascinating!
