What kind of camera (and what resolution) do you need to make a movie theater standee size/quality print?

The printing itself won't be a problem for me; I have several options withing walking distance. I'm just wondering how feasible it would be for me to rent/buy such a camera to make a portfolio presentation.


Answer
You don't necessarily need something monstrous with a ton of megapixels - photographers have been creating photos for up to billboard-size with cameras like the Canon 1Ds Mark I, the Nikon D1X and other, relatively low-megapixel cameras for years now.

There are a couple keys: you need a great original image that doesn't require much, if any cropping (RAW would be great, but JPEG is fine).

The biggest thing is figuring out what the final resolution needs to be - a movie standee that's six or eight feet tall is designed to be viewed at a much greater distance than an 8x10 print hanging on the wall, so it doesn't need to printed at 200 or 300 dpi; it may need something more like 75-100 dpi, or possibly even lower.

Obviously, if there's something with fine detail in the picture that needs to be reproduced, you'll need a finer resolution, but check with your printer first.

Also, you can always interpolate up your images - if you shoot RAW, the RAW converter that came with your camera frequently allows you to import the file at a larger file size, but there are plenty of software options for interpolation. Genuine Fractals is probably the best of them.

If you already have a DSLR with 8-10 megapixels, you're totally set; if you really want a ton of extra detail, rent yourself a 1Ds or 1Ds Mark II or a 5D.

How can one display an image that has a greater resolution than the screen ?

What exactly is a resolution ? Can one view images with resolutions greater than the resolution of the screen ? How does the megapixel of the digital camera relate to the image resolution and image quality ? There's a new mobile from nokia coming with a 41mp camera , what would the screen resolution be of the photos taken from that camera ? Could one view it on a full hd screen ?

Please clear my doubts. I will choose a best answer.

Thanks !



Answer
Lets say you have an image that is 4000x3000 (12 megapixels)
And you view the whole photo on a screen with resolution 1000 x 750. (1.75 megapixels)


The screen simply displays a grid of horizontal and vertical lines formed from every 4th line of pixels or averages out every group of 16 into a single pixel.
