To print this image at its highest quality which is at 150 DPI, the image comprised of 3000x2400 pixels must be printed at a size of 3000 px ÷ 150 dpi = 20 inches wide by 2400 px ÷ 150 dpi = 16 inches high. To further clarify, let’s take our previous image with pixel dimensions of 3000x2400 pixels. In the printing industry, the term resolution can be used interchangeably to describe dots per inch, or defined in the pixel dimensions. What this means is that for every 1 inch of the printed image, either width wise or height wise, there are 150 pixels in that measured row or column of pixels. When printing high quality & detailed images for large format lenticular, a DPI of 150 is ideal & recommended.
Here's a useful guide from a stock library agency: Alamy.DPI (also known as ppi) is an abbreviation for dots (or pixels) per inch and it’s used to define the print resolution. There's no hard and fast rules for stock library resolution requirements, but as a rough guide, you should be looking to get a dSLR camera 10MP and above (you might just get away with 6MP or less for web use only) and remember you'll need model release forms for people featured in your images.īe sure to check the terms and conditions of the agency you're submitting your work to very carefully and think twice before signing off your very best photos. WANT TO SUBMIT YOUR WORK TO PHOTO AGENCIES? Woohoo! Fantastic quality print, full of detail and perfect for your picture frame or for your showing off your very best shots. This will be fine for most uses, unless you get up reeeeal close Pretty good all round, with a fair bit of detail Looks reasonable enough, but nowhere near photo quality Horribly pixelated blocky mess, like something out of 1987 This guide shows you the kind of quality you can expect when you're printing out your photos. Kodak, for example, suggests these resolution/file sizes:įor a 4" x 6" print, the image resolution should be 640 x 480 pixels minimum.įor a 5" x 7" print, the image resolution should be 1024 x 768 pixels minimum.įor an 8" x 10" print, the image resolution should be 1536 x 1024 pixels minimum.įor a 16" x 20" print, the image resolution should be 1600 x 1200 pixels minimum.įor a 20" x 30" print, the image resolution should be 1600 x 1200 pixels minimum.įor a Wallet-size print, the image resolution should be 320 x 240 pixels minimum.
