Resolution can be defined as the number of pixels that, in constellation, make up an image or photograph. Pixels are small dots in the image that can have various colors. Digital photography uses pixels to create photos. Image sizes in photography are measured by the number of pixels in width and depth. The measurement is generally determined as resolution. Computer screens use the same measurements as digital photography. The most typical are sizes like 800 x 600, 1024 x 768, 1280 x 960, 1280 x 1024, etc.
The general thing about digital photography is the number of pixels. Different resolutions create different images. The more pixels an image has, the more elaborate it is. The details depend on the number of pixels. But larger resolution also means larger image file size and larger print size. This can cause some difficulties if you try to print the image yourself. Larger file formats also cause problems when sending files via email: some email accounts have a specific space and their attachments are too large to receive them. Despite this, people prefer a resolution with a higher number of pixels. The image looks much more realistic when more pixels are built. It’s the same as in the puzzle game: the more pieces a puzzle has, the more complex it looks. Pixels provide additional shades and hues because they can take on different colors, making the image look as real as possible.
Let’s discuss the pitfalls of file and print size. With a 3 megapixel camera, you’ll have no trouble printing 8×10 or smaller photos and you’ll get satisfying results. If you want to print something bigger, you will get into trouble. You’d better go to a print shop. For larger prints, you may need special paper and a professional, who can do it for you. Another thing to remember is resizing. You can change the print size without making resolution artifacts. But this can only be done when an existing photo is downsized. If you decided to enlarge a small image using a program, it is better to leave it. The smaller images are made of different resolution formats and when you enlarge them the number of pixels stays the same and it is no longer supported by the larger copy so the quality of the photo is lost.
The resolution also defines the size of the file. You can try converting larger files to smaller ones before sending them via email. Before resizing an image, it’s best to save it at its original resolution quality. Save it at its largest, pixel-rich size, and then make it smaller in your email editing program. In that case you will always have a copy of the original in case you want to print it. Remember that once resized an image cannot go back to its previous size as it is bigger and the resolution would change for worse. This effect is called pixilation: when you try to enlarge an existing copy. It always results in poorer print image quality.
There are three points to remember about resolution.
1) The higher the resolution, the better the quality of the printed image.
2) The higher the resolution, the larger the file size and the larger the print size.
3) Don’t confuse pixels with dots. They are not the same. Pixels per inch (PPI) and dots per inch (DPI) are completely different variables from each other.
