The idea is to increase the X-Y resolution of the image so that 600 pixels will print every inch. People who are really into high quality printing do get into the concept of DPI.

The printing software will simply take 4288, divide it by 6 (6 inches across in a 4圆 prints) and lay down 714 pixels for every inch of paper (well, it’s more complex than that, but that’s the essence.) That never changes (unless you explicitly change it.) In your case it’s 4288 x 2848. Your images have an X number of pixels and a Y number of pixels. The reason is that we usually print borderless. When it comes to printing images taken with a digital camera, this value is, for the most part, ignored. That’s how the document is reproduced in its original size. The receiving fax machine prints the received image based on the DPI that was specified. After two fax machines agree on a communication protocol, the sending fax machine sends the image data and the DPI setting. Fax machines can scan at multiple resolutions.
Without knowing what DPI the document was scanned, it is impossible to know what the original size is.Ī perfect example of this in action is a fax machine. Recording this value allows a printer or other display system, to display the document in its original size. The purpose of the DPI value is to record the scanning resolution of a scanned document (or image.) A scanner's resolution is defined in Dots Per Inch (for no good uld have been pixels per inch, but it wasn't) so it is appropriate that this value be called DPI. More important is to understand this value's purpose. When it isn’t, the software will display a default value. The DPI value is sometimes set by the camera. More than 300 dpi wont help, it is all THEY can do. 180 might be about acceptable in some cases, and 180 might be about all the little ink jet printers can do, but if sending it to be lab to be printed, strive to have enough pixels for 300 dpi if possible. I was at a Nikon seminar recently and the instructor said he prints as low as 160 and sees no loss of quality. for printing purposes, there have been studies showing 300 is overlkill. Digital images are dimensioned in pixels. the camera has no notion of inches or dpi or ppi. dpi does have another use, pertaining to printer ink drop spacing, but the context makes it be clear (like all other English words).īut. The fact which we must understand is that these are used interchangeably. Newbies seeing it for the first time seem to like ppi better, but the terms are used interchangeably if it pertains to images. Both terms mean the same pixels per inch, when about images. It may be jargon, but it is popular usage, and it is not wrong. This is what applies to the resolution of your photos.ĭpi is the term that has been used for many years. So who are you gonna believe, the big boys, or this guy? Also any scanner is rated in terms of dpi, meaning exactly "pixels per inch". Also check Microsoft, in the Paint program in all versions of Windows. they use it incorrectly).Īnother case of "all the world but me is wrong - only listen to my notion". (ignore Capture NX's use of this term, if you use that. The only number that is real is the 4288 pixels dimension of your image.ĭPI = dots per inch. This 300 dpi number simply shows that 4288 pixels will print 4288/300 = 14.3 inches on paper (if you so choose), but this is not likely your actual goal.
There are no inches in the camera, and no knowledge of the size you will wish to print it. The camera may choose to arbitrarily stick 300 dpi there, but it has no probable meaning. There are no inches in the camera, and none in the video system. You can assign any dpi number later, which merely controls the inch size it will print on paper. There are no inches, and there is no dpi. You shoot and create some number of ipixels, like 4288x2848 pixels. If you instead use Adobe menu File - Save As - JPG, it will retain the Exif data in your JPG file. When there is no Exif dpi information, Adobe will show 72 dpi, but in fact, there is no number present. (because video and the web simply have no use for dpi). This menu strips away all Exif data, including JPG dpi.
#Photoshop inkdrop tool how to
Can anyone tell me how to guarantee that my photos will always be in 300 resolution?īecause you probably are using the Adobe menu File - Save for Web option. I have done experiments with lighting, turning off active D-lighting, and shooting in RAW instead of JPG fine, but nothing helps. I want to shoot all photos at 300 resolution. I have a Nikon D5000, and I just noticed that some of my photos come out in 300 dpi, or resolution, and some come out in 72 resolution when I put them into photoshop.
