Image size?

[gramps]

Let me start by stating that I haven't even tried to figure out RAW files yet. Now on to the question. Using a 20 D if you shot three pics of the same subject, in three sizes ( S, M, L jpeg fine ) and all three pics are exactly the same, when you crop (no resizing) a 12 x 8 section (the same section out of all three) can you get more detail, thus sharpness, out of the large picture.

I just answered this one myself............shot a large and small, cropped out the same area.................it has the same amount of pixels. Now I'll test the sharpness of the two.

small and large are not going to have the same amout of pixels.

If you crop and upsize they will. The quality won't be the same though.

Gramps, you will see adifference in the three.

Large has 8 mega pixels 3504 x2336 blow up to 16 x 20

Medium has 4.3 Mega pixels 2544 x 1696 blow up to 13 x 19

Small has 2 Mega pixels 1728 x 1152 blow up to 5 x 7

The above are fine settings.

for normal Large I asume it is 6 Mega pixels
for normal medium I assume it is 3 Mega pixels
for normal small 1 mega Pixel.

With the large fine you can crop 50% and still have a 4 mega pixel image for large printing.Where di you get they had the same pixels.

Hi phili1,

Do you get these sizes using jpeg?

Just a suggestion, figure out RAW files.

I recently shot a few JPEGs because I thought I might need more space on my CF's, but it's no good. Maybe in natural light, sunny day, etc. but with a flash or any artificial lighting and the WB is off, you (camera) easily over/underexpose, etc. Thing is, when you make a shot that is perfectly exposed, right WB, properly focused, it really doesn't matter if you shoot RAW or JPEG, but very often, things aren't perfect and JPEG won't make it easier for you.

If you had enough money for a 20D, you'll surely scratch a few more bucks for a large enough CF. And possibly X-Drive.

That is JPG raw is only one size 8 mega pixels.
