not shooting at full res

[freefallu]

Hi,

When you reduce the res of a photo with for example the 5d or 400d what is happening in the camera ? Are you reducing the amount of the sensor you use or is the same sensor area used. I am wondering if you are using more sensor for less picture ( mp wise ) would that mean you get better quality from the camera ?

basically, same sensor size, just resized smaller. no dslr to my knowledge has digital zoom :). as far as quality is concerned, not really. you will get better quality prints from the full res files, same goes for if you resize the full res image in photoshop.

The only reason I will sometimes use a lower res is when I am shooting ebay pics of trading cards or comics and I am only doing a slight crop, still leaving me with images more than large enough for ebay. It lets me get almost 900 pics on one card, they transfer, open and batch process faster.

Aside from that I never come down in res because I want the flexibility of being able to crop and work from the largest possible master I can.

Have no idea. I never move the quality setting of maximum. :)

Set it lower..shoot some shots exact same all regards, then processed and blowem' up.
Look for/at the difference.
Simply the camera is basically storiing less of the electronic image information that it is capable of.
Sensor is same size used.

They only use to do that in video camcorders to increase sensitivity. They use 3Mp CCD's, yet read the data from clusters of 4 or 9 pixels for an image pixel (averaging to rule out noise). The results are 0.4Mp images (720x576 PAL).

ok thanks, adas you answered it like i was trying to put it :) I bought a 400D on impulse just to have a carry around and am now thinking how do i get the most out of it .
