To Make a Print of Your ImageWe’re going to assume you want to make a print of this file. For starters, let’s find the size print we can make from the file. For this we need to know how many of those pixels your printer needs for each inch of print. Printers these days seem to have settled at 300 pixels per inch (ppi) and this is true whether you’re home brewing or uploading to an online lab. So, using our maximum dimension of 6000 x 4000, we divide each number by 300. This gives us a 20 x 13¼ print. That’s a good-sized print using all those camera-original pixels. Smaller Print? If you want a smaller print, software will enable resampling to downsize your file. It uses some high cotton math (algorithms) to accomplish the conversion, but the resulting file will print just fine. To learn more about resampling, visit the Real World Adobe Photoshop CS5 for Photographers Fundamentals: Resampling in Photoshop CS5. Larger Print? If you want a print larger than 13 x20, then the resampling magic will do the trick just as well. I’ve made very beautiful 40 x 60 inch prints from my 24MP files. If you’re willing to invest some time and diligence learning about printing, the rewards of making a well-crafted print are enduring. I recommend you give it a try. More later, Tony Roberts
