Image Sizes
The site gives you the image sizes in pixels, and also the size on disk and the image size. This sounds complicated but it is fairly straight forward. This information helps you to decide if the image will suit your purposes. Obviously not every image is suitable for a billboard.
The image size in pixels is your starting point. Essentially how many pixels across and high that the image is. In general the larger the better would seem to be the case. Although again things can get murky. For example it is not too hard to adjust an image to have 10x as many pixels...although the quality will obviously suffer from the interpolation. That is when a resize is done, the computer essentially makes a best guess at how to fill in the extra pixels.
The size on disk is pretty much that, this is the file size that you download.
The image size is an uncompressed pixel count. Depending on compression it is roughly three times the uncompressed image size. Three times since there is a Red, Green and Blue image used to make the composite final image. This information can be used to help you decide on the quality and compression of the image.
All of our images are published at 300ppi, which is an industry standard for printing. This means your print size is simply the amount of pixels divided by the ppi. So for example, if the x pixel dimension is 3000 then the print size at 300ppi would be ten inches. This can be treated as a guideline, since for example a print output at 240ppi can give just as acceptable results depending on usage. In this case you would have a 20% gain in size.
Images as mention can be enlarged using software, in this case the software will fill in the "missing" pixels to create the required size. The trouble is this is often a matter of trial and error. Some images will enlarge well and others just look terrible. It also depends on the desired end result. Many of our images will enlarge well to poster size, some wont.
Generally the enlargement quality will work better with either very very good quality images to begin with, usually in a brighter light as the CMOS sensor of the camera will generate less noise. Or if the image is fairly chaotic. To explain that better, a clear sky will show more noise on enlargement than say a picture of forest. Again there are no hard and fast rules with enlargement.
All of our images include two captures of the original image, one from the center and one from the lower left corner. These captures are taken from the original image at the original capture size. This allows you to make an informed decision on how much you think you can enlarge the image if needed. Again, if there are any questions just ask.
Our files are generally at the range of most modern DSLR equipment. That being in the sizes 3-6000 in terms of pixel size. This is pretty much the industry standard range and covers most print and media applications very well.
If you have any questions or concerns dont hesitate to ask.
