Now, a pixel itself is a single picture element – and for our purposes, it’s the smallest element that your photo can be divided up into. The image above shows the resulting information dialog box. In Photoshop, you can open your image, then choose File > File Info > Camera Data. You can check the width and height of an image using your photo editing software. You and I might call this 14.5 MP, but camera manufacturers round this up and call it a 14.6 MP camera. So by multiplying the number of pixels along the image width by those along the image height, we get the actual number of pixels in the image (4672 x 3104 = 14,501,888). So the ratio comparing the number of pixels along the long edge of the image to the short edge of the image is 3:2.Įach of my full-sized RAW images is 4672 x 3104 pixels in dimension. My camera, like most DSLRs, captures images with an aspect ratio of 1.5. This information tells you nothing about the actual pixel dimensions of the image – it only tells you the total number of pixels that make up the image. So my camera, for example, captures 14.6-megapixel images, which is around 14,600,000 pixels per image (14.6 x 1,000,000). Technically, a megapixel is equal to 1,048,576 pixels in reality, camera manufacturers round this number to 1,000,000 when stating how large of an image the camera will capture.
