![]() The PPI/PPCM value is optional and if it is not filled the crop will simply adjust to the ratio of the values input. You can also mix and match values between width and height if desired, or if you just like doing math. After a number, you can put in px, in, cm, mm, pica, or pt, which are short for pixels, inches, centimeters, millimeters, picas, and points (respectively). The width and height fields allow for multiple types of measurement values. In addition, there is a third field for inputting the pixels per inch (or pixels per cm). Using the W x H x Resolution option, you can input exact dimensions for your crop in the fields that were previously used for the ratio values input. This isn’t necessarily true for the next option, W x H x Resolution. Pixels may be removed from outside the crop area itself, but the pixels within the newly cropped image will be unchanged. It’s important to keep in mind that when using the Ratio option for cropping, the image is not being “resampled” as no pixels are created or deleted within the crop area. This will empty the input boxes and works with both the Ratio options and the W x H x Resolution option. While we’re looking at this area, you will also see the Clear button (yellow box in figure 4) to the right of the input boxes. You can swap the ratio numbers anytime by clicking on the two opposing arrows (red box in Figure 4) between the ratio input fields, making it easy to switch from portrait to landscape orientation. This will constrain the crop box to those proportions. For instance, if you have a printer on which you print 13×19-inch photos, you can input 13 and 19 into those boxes. While there are several presets in the list, you might have a specific use. Using the Ratio option allows you to input your desired proportion of width to height using the two fields to the right of the pull-down list where Ratio is selected. ![]() Of course if you know that you will need to make an 8×10 or similar proportioned prints, you can leave space when shooting your photos. In this case, I might instead make an 8×12 print as I don’t want to cut that much of the image away. In Figure 3 you can see an example of how an image that is in the 3:2 ratio gets cropped when adjusting it to fit into an 8×10 print (5:4 ratio). Something will need to be cropped out in order to fill the print paper, or you’ll have to leave a border on two edges, which is usually not desired. This is because we’re going to an image at a 5:4 ratio for an 8×10 print from a source image that is at a 3:2 ratio of width to height. APS-C sensors are also in the 3:2 ratio.įor example one of the most popular enlargement sizes is 8×10 inch prints, however, the 3:2 proportion of 35 mm full frame images (film or digital) requires the image to be cropped. Note: Most full-frame sensors differ slightly from exactly 24x36mm, and this varies across brands and models of full-frame cameras. Since 36 by 24 can be divided down by 12 the final ratio here is 3:2. For instance, a “full frame” DSLR or mirrorless camera has a sensor that is very close to 36×24 mm frame size, which is the size of the negative or slide a 35 mm film camera produces. When talking about ratio, we’re referring to the proportion of an image’s width to its height. Before we get into the presets, let’s first look at using the Ratio option. Any presets you create will be listed above the New Crop Preset text in the list. There is also an option to save a preset to this list, as well as an option to delete presets that you create. Additionally, Adobe provides a list of common ratios followed by a list of some commonly used specific sizes for prints and computer display sizes. ![]() ![]() You can also save them in the next pull-down list to the right, which we’re about to get to Figure 2Ĭlicking the next pull-down list in the Crop toolbar allows you to select cropping by ratio or by exact dimensions and resolution. You can also save your current crop settings here if desired. This list can also contain all presets for all tools by checking the option (gear) icon when viewing the presets. Clicking on this will present a list of presets of some standard photo print sizes from 3×5 inches to 8×10 inches, all set to 300 PPI. In the crop options toolbar, the first icon you’ll see is the Crop icon itself. Some of these options can impact the image quality of the cropped image, so it’s important to understand how these work. Once you’ve called up the Crop Tool, you are presented with various options on how you will proceed with the crop. The C shortcut is also shared by the Slice Tool which can be used to divide an image up into multiple sections. The Crop Tool has a second mode called Perspective Crop that can be accessed by holding down your mouse click on the icon or by holding the SHIFT key while pressing C.
