Next, divide the number of pixels in the height of the file by 200. (1600/200=8). So, there you have it. A file size of 2,000 pixels X 1600 pixels can be printed to make a good quality 10 X 8 photo when printed at 200 DPI. The orange result box first shows what your current numbers wants to print at literally whatever resolution it computes (but if no better action is taken, it likely still does not match the print paper shape). This is also what you would get now at the one hour photo lab (as much as the surprising crop on the actual paper size can provide). Can't be done proper without some attention first. The one-hour print lab is not expected to handle the "crop to shape" in any good way that would please you, because humans don't see it. Their automated printer machine does it today, which simply doesn't see or recognize your image content. It just cuts off whatever won't fit on the paper, which simply disappears. It's your job now, to crop to show it how you want to show it. If you decide to make a print at 300DPI from the same image file, you will have a print with better resolution. However, the maximum size for a quality print will be smaller.

The maths would be.... 2,000/300=6.8. Next, 1,600/300=5.3. So, if you round the numbers out, the maximum standard size for that print will be about 7 X 5. This might sound like a simple mathematical formula, but it is precisely how to measure the square footage of a rectangular room in real life. We just need to measure two consecutive sides in feet and multiply the values together. The maths involved to come up with that size print is to first divide the number of pixels in the width of the file by the 200 DPI. (2,000/200=10). But that is just a choice, and the difference is small, and it will be difficult to realize a difference from scanning at 1548 dpi. There is another different mild compromise which is reasonable at times. For example, at the calculators initial defaults above (scanning 35 mm film to print on 8x10 paper), Button 2 at 300 dpi computes to scan at 2540 dpi. Which is close to 2400, so instead of increasing to 4800 dpi, try Button 3 at 2400 dpi, which computes printing at 283 dpi, which should be very acceptable. You'll never see the difference from 300 dpi, and the local one hour lab probably prints at 250 dpi anyway.

How to do Multiplication with Decimal

If your image dimensions are too large, the photo shop will first resample it to this smaller requested size. That's not necessarily a problem, except a far too-large image will be slow to upload. Or, if too small (insufficient pixels provided), the print quality will be lower, and the lab may refuse worst cases. But if the provided image shape does not match the paper shape, the excess image outside the paper edges simply disappears, results may not be what you expected. When a printer prints at 300 dpi, it spaces the pixels onto paper at 300 pixels per inch of paper. Printing 3000 pixels at 300 dpi prints a 10 inch image on paper.

Given that I have many clients, on various courses, and other events wishing to create prints, I felt a guide to the considerations and technicalities would be helpful. Just to be sure you are aware, Scaling is an option in the scanners menu that is a multiplier for resolution that scales output size. If you set the scan to 4x6 inches at 300 dpi at 200% scale, it will scan the 4x6 inches at 600 dpi (will create 2400x3600 pixels), but will set the image files dpi resolution value to the specified 300 dpi so that it will print 2x size or 8x12 inches size on paper at 300 dpi. That's the meaning of Scale, and the scanners meaning of Input and Output (what we scan, and what we get). While most scanner menu boxes don't show the 600 dpi number, it shows the 200%, and should show all of these inch and pixel numbers (scaling discussed more). This scaling is mentioned in the calculator Button 2 and 3 results, but below, I am speaking of 100% scale, which is NOT multiplied (100% scale multiplies scan resolution by 1, which has no effect). Find the product of multiplicand and most significant digit (MSD) of 3-digit multiplier, and write down the product under the earlier product but the One’s place value of product should start from the Hundred’s place value of multiplicand. Having spent countless hours capturing images, editing images and probably re-editing and selecting images your now at the stage of getting a set of prints ready. How does aspect ratios relate to cropping? The image below is a full frame 3:2 image. If we printed this as a 6×4” print, it would not need cropping but what if we wanted this image in another common print format – a 10×8”?

Preparingtheimageshape to fit the paper shape is necessary, because paper and image are often different shapes. So scan and then for printing preparation, FIRST crop to paper shape. Crop as desired to both fit paper shape and also to adjust crop size and location to improve artistic composition — keep important detail, and crop away only the unimportant - Duh. 😊 But it is a choice that you can make while you are seeing it. You can make this crop be the best size on the image, and placed at the best location, but the shape will be fixed, matching the declared print shape. Then SECOND, resample that cropped image to be the smaller desired size to print (pixels, for example 3000 pixels for 10 inches at 300 dpi). Cropping to match paper shape is normally about trivial to do (see procedure). We must choose this ourself. Both Size and Shape are important, and while you're dealing with "crop to shape", why not also resample it to a much more reasonable size first? (see next Blue step). If printing yourself at home, the Print menu in your photo editor normally does use the file's scaled image dpi number (pixels per inch) to size the images on paper (regardless if it matches the paper size at all). But it typically will also allow changing that dpi, called scaling (to fit the paper size). For example, if an image dimension is 3000 pixels, then specifying that file number as 300 dpi printing resolution will print it to be 3000/300 = 10 inches print size (even if the paper is only 4x6). But the dpi number that your digital camera initially stores in the image file, unless you have reset it to your planned value, is otherwise far from meaningful, it is just some arbitrary number, which will print SOME size, but not likely to be your own printing goal. Hopefully, you have already properly scaled the image for your selected paper size. Example when wanting a print size of around 12 inches on the longest side with an image in 2:3 aspect ratio
