![]() ![]() There are numerous factors that each need to be considered before determining if an enlargement is possible, which include: Anytime an image is resampled and enlarged it will reduce quality the key is to preserve as much detail and sharpness as possible. There are no concrete rules when it comes to image enlargement. "Northern Exposure", Gates of the Arctic, Alaska. This article will discuss the best software, methods and limitations for image enlargement. You do not have to be a pro or pay a lot of money to get amazing results. Maybe you want to take an iPhone photo and create a 12x18” print, or perhaps you have 36 megapixel image file and need to create a 100” print for a client. However, with the advanced software tools available today, images taken on low resolution cameras, iPhones, or old film scans can all be transformed into detailed enlargements. If done improperly, the resulting image enlargement may be grainy, soft and generally of poor quality. Even with today’s high resolution full frame digital cameras that have 45-60 megapixels, photographers often need to resize their images. That's why Apple’s “ Shot on iPhone” billboards look great.How to Enlarge A Photo for Print Without Losing Qualityĭigital image enlargement, or resizing, is the process of increasing the resolution of an image to produce larger prints, posters, wall art or even billboards. With a bit of Photoshop work, you can easily double that, and if you’re prepared to sacrifice a some quality, there is really no limit as to how big you can make them. With no tweaking, you’re normally able to print a high-res images that are over a foot wide. With my iPhone 6S, that gives me prints that are over two feet wide that look good when viewed up close. I’ve found you can safely double the horizontal and vertical resolution (so quadruple the size of the image) of a good quality file without too much loss of quality. The further you push things, the worse they’ll look. While there’s no limit to how much bigger you can make an image in theory, Photoshop only has so much data to work with. I’d sooner print this version at 300 PPI than have the printer do a version at 200 PPI. There’s definitely a small difference, especially in areas of fine detail like the hair, but I think the effect is still really good. Why let some stranger make decisions about your images? While you can just let the printer do their thing, it’s normally better to take matters into your own hands. Option Two: Increase the Photo's Resolution If you send them a 12 MP photo and ask them to print it on a 20 inch wide canvas, all they will do is print each pixel a little larger.Įverything will look good from a few feet away you just won’t be able to stand as close. At 200 PPI, you can print a 12 MP image on a 20.16 inch by 15.12 inch canvas. Lowering the PPI is the option most printers will take if you ask them to print a large canvas. So if you want to print a bigger image, you have two options: lower the PPI on the print, or artificially increase the image size. You can get away with having a much lower PPI. No one (sane) tries to put their nose against a billboard to see what it says. ![]() For larger images, however, if you get too close, you can’t see everything. People want to get close to see everything. For small images, this is really important. At 300 pixels per inch, you can put your nose against a print and it will still look good. ![]()
