A4 Size print
Hi guys, just wondering how much megapixel i should set if I wanna do a A4 size printout, with a decent quality on the photo? My digicam is only capable of up to 3.3mp only, is this enough?

Not quite enuf...You can still see the pixelation on the printout.

I do A4 printout quite frequently, and using Glossy photo paper too.
I'm using HP deskject 930c (old printer), that can print at 2400x1200dpi.
The picture were printed using ACDsee 6.0 software, and were enlarge using B-spline filter...
I dun think pixelation is bcos of my printer, bcos I have printed pictures taken by 6MP cam.. and the printout is excellent....
Oh.. and if the picture taken by your camera has a lot of noise.... dun be surprised to see lots of reds and blue dots in the picture....

2MP is not enough... boy, I'm learning new things everyday

2MP is not really good enough for A4 size prints if there're a lot of fine details, e.g. landscape shots. For portraits, it should be ok. Of course this is subjective and depends on the viewer's level of acceptability.
3MP would get you decent A4 size prints. You could still get more details with a higher MP camera, or a camera with larger sensor (e.g. DSLRs).

I actually matters what printer that you use to print. The newer higher resolution printer using a better stochastic dithering algorithm would allow the dots to look less obvious as well as distribute out the noise.

I used a Canon G2 (4m) and produce A1 poster,

Allow me to confuse you about digital image workflow to get good print:
the quality of the camera esp the ccd
the quality of the image capture (this depend on the guy who hold the camera)
the right process during post-processing (what you do to the image with software like PS)
the know how about colour management
the quality of the printer
the media choosen for the print
and the person who eventually receive the print.

if i am not wrong, magazine prints from 130 to 150 dpi typically with exceptions of glossy covers. but then again a 300dpi image is normally used to print out the file becos of the colours, something like that.
i tried printing a 3 megapixel file to A3 size and i noe of pple who have printed 1 megapixel images on A3 and they dont look bad at all.
depends on what printer and paper you use. and the post processing is important. how u process ur 3.3 megapixel image (with reference to thread starter's camera), upsizing the image.
hope it helps.
a few links here to suggest.
just my 2 cents worth. hope u can print better

!!!( The section on printers and DPI)
can try go and borrow this book called Digital Pre Press Complete i think. quite useful, forgot if it talks abt this issue on resolution but sure helps in making all prints including photos turn out as what you want.
a good book to learn how to print big poster size prints will be Photoshop for the Digital Photographer, i borrowed from National library once. very good workflow and works.
