![]() ![]() In the end, images that have been converted to High Res from Low Res often look blurry, out of focus, and distorted. The photo program can’t create details that aren’t there in the low res (72dpi) version. Compare the same area in each image above - notice that multiple pixels in the 300 dpi image became one pixel in the center image? And then from one pixel to several in the image on the right. Most noticeable in the above example is the one bright yellow square in the upper right quadrant of the center image. ![]() Compare how the photo editing software converted the color to pixels in each image. To understand this process more, we need to look at what is happening at the pixel level within the photo program’s algorithm. Then, it has to interpolate color from the surrounding pixels and make an approximation. Remember earlier when we touched on how several pixels are converted to one pixel of color? The photo edition program reverses the process in converting Low Res to High Res, except the software has to create the additional pixels. Notice how it looks blurry and out of focus. A 72 dpi image is saved as a 300 dpi image. You can technically the photo programs will do it, but it doesn’t work in practicality. IT DOES NOT WORK! You cannot simply save a 72dpi Low Res image as a High Res, 300dpi image. You may be thinking - Yes, I can! My photo program does it without any problem! But, no, it doesn’t. You Can’t Go Back from Low Res to High Res! In other words, it’s converting a little over 16 pixels in a 4×4 arrangement to 1 pixel. Taking 300 pixels per inch down to 72 per inch. But in the photo program, you’re using, its algorithm interprets the colors of multiple pixels and converts them into one pixel. In this enlarged view of the same area, notice the square pixels in the Low Res 72dpi image.įor you, it’s a few clicks of a mouse to change the resolution of the image. You probably don’t see any difference if using a tablet or smartphone. Usually, the only change you’ll notice during the process is that the image reduces in size on your computer screen. It’s easy to convert a 300dpi High Res image to a 72dpi Low Res image with just a few clicks of a mouse or taps on a screen. Understanding the Conversion Process Going from High Res to Low Res print promotional items such as postcards, business cards, posters, exhibit catalogs.These features make Low Res images ideal for:Īs a general rule, you should only send High Res (300dpi or better) images of your artwork when requested, and to destinations, you trust for: ![]() In addition, being low resolution, the file does not enlarge or print well, helping to limit the unauthorized use of your image.

When to use a Low Res Image of Your Artwork ☺ © Nancy Murty | Summer Meadow | 12×8 in | oil on linen | soldįirst, let’s quickly go over a few basics, like when it’s best to use Low and High Res images and the advantages for both. The only difference between the two is that pixels are used in digital applications and are square-shaped, while dots are used in offset printing. Oh, one quick note - I come from a print background, so by default, I refer to dots per inch (dpi) instead of pixels per inch (ppi). Instead, I’ll explain the fundamentals so that you will understand the foundation of image resolution and submit the best images of your art going forward. Helping you to understand High and Low-Resolution image settings is the focus of this post. But is it? Are you sure you sent in a true High Res or high-quality image of your artwork? So why does it look so bad?Īfter all, the image you sent was exactly what they asked for! And, so you conclude, it must be the printer or publication. Made sure to crop your image to include ONLY the painting no frame or other background. You made sure to send just what they asked for! Used the photo program on your computer, created an image file that met their specs - 300ppi (pixels per inch) and 1400–4000 pixels for the longest dimension.
