What is the best digital camera to buy if you're blowing up the pictures up to A3 size?

My curent camera, a Pentax s55, is struggling with resolution issues when pictures are blown up to A3.

when expanding an image using a digital camera the more mega pixels it has the better. most now use about 2 to 3 mega pixels however to retrieve a good quality expansion to a3 i would recommend trying to use a camera that has about 5 to 6 mega pixels. Also bear in mind how u r printing the image, as your printer n software have to be of good spec in order to transfer the image without loss of quality. most software now allows u to correct the sharpness of an image.

This is a great site for reviews and questions. the reviews of the digital cameras are detailed and very informative. there also is a form to ask questions and I have always found that the answers provided in that form are excellent

I would suggest a camera with 9 m,pixels and above and with raw files option rather than just jpeg. the more pixels the better it looks on a larger scale in A3 paper.

Make and Type are often down to personal choice and budget!

The Resolution of the CCD is what is important...... Anything over 5Mpixel should give reasonable results up to about A3.... But if you go for higher you have a bit more flexibility, and prices have come down alot!

I shoot with a Finepix S9500 these days, it's 9.2Mpixel and they're about 拢330..... and that's a lot of camera and lens for the money!!

Hope this Helps!

what you need is a least 15 megapixels digital camera.
A3 is around 11x16". you gonna print at 300 dpi (dot per inches). So what you need is (11*300) x (16*300) pixels = 3300x4800 pixels = 15 megapixels for best results

there's way more than one factor when spending a few hundie on new gear dude... check out kenrockwell.com... he has a very informative site explaining in layman and scientific terms all camera ?'s... and offers great detailed tutorials on shooting...

You need upwards of 10 mega-pixels, but also a good fast lens, since you will need to avoid softness and colour fringing, and be able to use higher shutter speeds to avoid camera shake.

I have a Sony DSC- R1 which has a brilliant Carl Zeiss 28 to 120 mm (35 mm equivalent) lens and a 10.3 mega-pixel CMOS sensor which gives the equivalent of up to 3200 ISO film speed.

It takes far better pictures than my old Canon 35 mm SLR and I now have so many A3 prints that I am running out of wall space.

For best quality prints, 3 MP or 4 MP can blow up to a max' of 8x10 or A4.
5 MP or higher is recommended for A3 and Poster size Prints.
You can print 3 or 4 MP photo's in larger sizes, but they will be grainy. That may be a bonus when printed at poster size (artistic an all!).

if you want to enlarge picture check to see if your camera has settings other than JPEG, eg. RAW TIFF etc. i use nikons proprietary RAW Images and the results are amazing. RAW images record everything the camera see instead of compressing them like JPEGs My Camera is the DigitalSLR D50
