![]() ![]() 4MP cameras give you photos made up of 4 million pixels, and so on. If you have a 5MP camera, your photos will be made up of 5 million pixels. This means that when I take a photo with my digital camera, the photo will be made up of 8 million pixels (approximately, anyway). Remember earlier when I mentioned that the camera I used to take this photo was an 8MP camera? Well, the "MP" stands for "mega pixel", and "mega" means "million", so "8MP" means 8 million pixels. To find out exactly how many pixels I have in my photo then, I can simply multiply the width times the height, which in this case is 3456 x 2304, which gives me a grand total of 7,962,624 pixels. In other words, it contains 3456 pixels from left to right, and 2304 pixels from top to bottom. ![]() So here, Photoshop is telling me that my photo has a width of 3456 pixels and a height of 2304 pixels. The dimensions and file size shown here are of the full size version of the photo above (the insect on the flower) before I resized it to something more suitable for a web page. It's also telling us one other important piece of information which is the file size of our image. In other words, how many pixels are in our image from left to right, and how many pixels are in our image from top to bottom. What Photoshop is really telling us is the width and height of our image in pixels. The term "pixel dimensions" here, to me, is confusing because it sounds like we're talking about the dimensions of each individual pixel, and that's not the case. For the moment, let's ignore the Document Size part and focus only on Pixel Dimensions. It's divided into two sections, Pixel Dimensions and Document Size. The Image Size dialog box can seem a bit frightening and confusing, but it's not meant to be and really, it's quite simple. In order to see exactly how large the photo is, once we have it open inside Photoshop, we can simply go up to the Image menu at the top of the screen and choose Image Size from the list of options, which will bring up Photoshop's Image Size dialog box, as shown below. Let's pretend though for the sake of this lesson that we're working with the full size version of the photo. Obviously, the photo you're seeing above is a much smaller version of the photo, since the actual-size version would be too large to fit on the screen. My camera, by the way, is an 8MP camera, and the reason why I'm telling you this will be explained shortly. ![]() I saw this little guy (or girl, who knows) posing for me on the flowers and happened to have my camera handy. Here's a photo I took one day while strolling through a park. Let's examine things further.ĭownload this tutorial as a print-ready PDF! Pixel Dimensions It has everything to do with how it will print. Image resolution has absolutely nothing to do with how your image looks on screen. It does, however, have everything to do with how your image will print. That's right, the resolution of your image has absolutely nothing to do with how your image appears on screen. So if it's not something you give up, has nothing to do with resolving an issue, and doesn't involve doves crying or partying like it's 1999, then what exactly is "image resolution"? Well, let me throw one more thing in there that image resolution has nothing to do with, and that's how your image looks on your computer screen. And, you're thinking of "Revolution", not resolution. Oh, I know! You mean, like, Prince & The Resolution, from the 80's - Purple Rain, Let's Go Crazy, that sort of thing?"Īnswer: "Umm. Well, kinda, in the sense that understanding image resolution can definitely solve a lot of problems. ![]() Question: "What about, like, 'resolving' a problem? That sort of resolution?"Īnswer: "Nope. And, I think you're actually supposed to give something up for longer than a month. Question: "Is it like a New Years' Resolution where I have to give something up for a month?"Īnswer: "Nope, not that kind of resolution. A lot of people, whether new to Photoshop or not, are confused by the term "image resolution". ![]()
