Resolution can be described as the number of pixels that, held together, form an image or a photograph. Pixels are tiny points on the image that can have different colors. Digital photography uses pixels to produce photos. Image sizes in photography are marked by the number of pixels in width and depth. The measurement is usually determined as a resolution. Computer screens use the same dimensions as digital photography. Most common are sizes such as 800 x 600, 1024 x 768, 1280 x 960, 1280 x 1024, and so on.
The basic thing about digital photography is the number of pixels. The different resolution makes for different images. The more pixels an image has, the more detailed it is. Details depend on the number of pixels. But the bigger resolution also means a bigger image file size and larger print size. This may cause some challenges if you are trying to print the image by yourself. Larger file formats also cause difficulty when sending files via email: some email accounts have specific space and your attached files are too big to be received. Despite this, people favor resolution with a greater number of pixels. The picture looks much more sensible when more pixels construct it. It is the same as in the puzzle game: the more pieces a puzzle has, the more compact it looks. Pixels give new shades and distinctions because they can take different colors, so the image looks as real as possible.
Let’s discuss the challenges of file and print size. Using a 3-megapixel camera, you have no trouble printing 8×10 or smaller photographs and get satisfying results. If you want to print something bigger, you will get into difficulty. You’d better go to a printing shop. For prints of larger sizes, you may need special paper and a professional, who can do it for you. Another thing to remember is changing size. You can change the print size without making errors on the resolution. But this can only be done when making an actual photo smaller. If you decided to expand a small image using a program, you’d better give it up. Smaller images are made of different resolution formats and when you enlarge them, the number of pixels stays the same and is no longer compatible with the larger copy, so the tone of the photo is lost.
The resolution defines the file size as well. You may try to change larger files into smaller ones, before sending them through email. Before resizing an image, you should better save it in its primary resolution quality. Save it in its more extensive and pixel-rich size and then make it smaller in the editing program for email. In that case, you will always have a copy of the original if you like to print it. Remember that once resized, an image cannot be brought back to its former size, as it is larger and resolution would be changed for the worse. This effect is called pixelation: when you try to enlarge an actual copy. It always ends up in more defective printing image quality.
There are two points you should remember about resolution.
1) The larger the resolution, the better-printed image quality.
2) The larger the resolution, the larger the file size and the larger the print size.
