My camera model is about two years old now, and it works great for 11 x 14 photos! Heck I even printed a 16 x 20 and it looked awesome. It has 10.1 Mega Pixels. So I'd say 10 is plenty but most cameras do have 10 now. Going for the older models is okay too, since they are cheaper. You can get the same photo really. I've seen amazing photos done with the camera I have. I don't know what else to say about all the photo stats there, though, what ones confuse you? The bolded?

I bolded the parts that I understand, especially the iso 80, so people won't say to change the iso for less grainy for exemple...

So to blow up pictures without losing quality that means u need a camera with more megapixels. . And bigger sensor.

Pretty much. The 1.5x or 1.6x crop sensors will try and cram xx amount of megapixels on a small sensor, losing quality. Full frame has a larger sensor area so pixel cramming isn't an issue.

Just do a simple pixel to inch conversion to see a rough estimation on how large you can print without harming the sharpness of the image.

You can print much larger of course but naturally, you'll have to stand back from the print.

Love Both.
But Cannon over Nikon

Could you please explan this in a very simple way?
Thanks in advance

especially since its canon not cannon

So, you're saying 12MP can only print up to 12 Inches without harming the sharpness???
Doesn't sound right to me ?

I've printed 20 x 30 with 12.2mp and had them produced very sharply that sold for over 200...

lol

Okay for example, my 5d will shoot around 4400 x 2900 pixels per image (roughly 13megapixel / 12mb raw file / 4mb fine jpeg)

Convert the pixel dimensions to inches. The easiest way, without calculating anything, is by opening up the image in Photoshop. Go to Image ---> Image Size (Alt + Ctrl + I) This will show you the pixel dimensions of the image and the inch dimensions. Or you can simply google a pixel to inch converter, they're everywhere.

Here's one which includes PPI in the equation (really good): http://tiporama.com/tools/pixels_inches.html

The image is roughly 60 inches x 40 inches on an lcd flat panel monitor which is displaying 72ppi (pixels per inch). So every inch of your monitor is display 72 pixels. This is quite acceptable on a monitor because digital pixels are alot finer than what is printable on photo paper.

Now the printing part, which is a little trickier. Your printer and monitor act differently in terms of output quality.

To print an image, you want at least 200ppi (alot more pixels per inch). If you printed at image at 72ppi it will be grainy, fuzzy and more often than not, unsharp. Although, this will keep the dimensions of 60x40 inches as stated above.

Now, if we change the ppi to 200, which will be the minimum needed for a fine print on an inkjet, our effective print size is reduced 22 x 14.5 inches.

Calculation?

Width = 4400 (pixels) / 200 (ppi) = 22 inches
Height = 2900 (pixels) / 200 (ppi) = 14.5 inches


This print will be the maximum size without having to stand back from it to view it as sharp. 22inch x 14.5 inch @ 200ppi.

You can print alot larger, but you will not be able to stand within inches from the print to admire the quality. More like a few feet.

I hope this has helped
