How is Resolution really measuredWithout overly complicating things, the resolution is what you see on screen or in print. On screen you see pixels of light and in print you see dots of ink. This is where the terms DPI dots per inch and PPI pixels per inch come from. In an over simplification, you can think of them as the same thing, however dots refer to print and pixels are a digital display. Many people mistakingly talk about DPI on screen, this is incorrect, but now you will know what they mean. Born To Be Riled there.

Onone Perfect Resize 7. DPI and PPI are both a way to describe resolution. You have heard the terms hi resoluton, or low resolution, or low res. This means how dense are the pixels or dots. More density more resolution, or detail. If there is not enough resolution image isnt big enough then you will see a noticeable softness to the image, or even jaggies also called pixelization. Too much resolution, wont affect the image display quality, you will just have an unnecessarily large file. So lets find the best resolution for your needs. The goal is to keep the quality as close to the original as possible and this article will show to how to do that. This is one of the big things that separate the pros from the amateurs, the quality of the final images. Digital Resolution explained. Every screen has a native resolution, maybe its 7. But a better way to measure screen resolution is with overall pixels. For example many monitors HD are 1. K Ultra HD is 3. A Canon 5d Mk. Megapixels Mega a million pixels. Print Resolution explained. Print is measured in dots per inch DPI LPI Lines per inch or line screen is used in commercial printing. If you have more dots in a square inch, you will have more resolution or detail in your print. Typical print resolution is 3. Microsoft Visual Studio 2005 Pro Final Dvd Iso Burner more. This means that there are 3. If your image is less, it will look soft, if its larger, there is no benefit as a printer cant print beyond its maximum resolution. Ok, how to tell if its the right size In Photoshop choose Image Image size. Turn OFF resample. Enter your target resolution into the Resolution filed, in this case 3. DPI, PPI is the digital equivalentYou will now see that a 9. If you need to it print larger you either need to select a larger image or scale the image up resample. The problem with sampling up enlarging is that you will lose image quality. The larger you make it, the more quality you will lose. If you need to scale the image down reduce then the quality loss isnt so much as issue, although you may need to sharpen an image if you shrink it too much more about that soon. How to describe an image size. If someone asks for an image of a certain size, just saying 46 inches or at 3. Sometimes people even go as far as to say 3. Mb, this doesnt help either because the file size doesnt really have bearing on the physical size of an image because file compression and file type all effect this. What you need to know id one of 2 things, either. The overall pixel dimensions. Say 3. 00. 0, 4. 00. Provide the target size AND resolution. For example, 46 inches at 3. DPI3. 00. PPI. See how to crop to an exact size and resolutionResizing an Image and Photoshop Interpolation. When you change the size of the image, Photoshop has to recreate the pixels. Photoshop needs to know how to jam the pixels together and which ones to throw away when you scale down. It also needs to know how to create pixels when scaling up. This process is called resampling. When you scale an image even by a single pixel, the entire image is resampled or rewritten. This is why creating the image at the correct size in the first place is great. However, dont fear, Photoshop does a really great job of resampling and many times you will never be able to see the difference in quality. In order to resample, Photoshop has to do some math to know how to recreate pixels. This math is called interpolation in terpol ation. Interpolation is important because certain types of interpolation will give you better results for different types of images. Im going to attempt to keep this as non technical in simple language and guide you to the best options. There were originally 3 types of interpolation in Photoshop here is a non scientific way for you to look at them. Nearest neighbor Think of this as looking at the nearest pixel and matching its color and tone. Bi linear Think of this as looking at the 4 surrounding pixels and finding the average. Bi Cubic like looking at the 1. But giving more weight to the 8 closest pixels. Typically bi linear is best for line art and simple graphics, where are bi cubic is best for photos and graphics containing gradients, but wait, it doesnt stop here. Adobe added 2 more types of Bicubic In Photoshop CS3. They added Bi. Cubic Smoother Smoothens out artifacts created in enlargements. Bicubic sharper Sharpens to bring back lost details while reducing a fileSee what features were added in which versions of Photoshop in our free superguidesThere are 2 more options what are they Automatic Photoshop CS6, it selects Bicubic Smoother CS6 Preserve Details CC when enlarging and it chooses Bi. Cubic Sharpener when reducing images. Automatic is easiest most of the time, but keep reading because it might not best the best option all the time. Stair Step Interpolation. There is a secret squirrel handshake for experienced Photoshop users in the know. This secret is often credited to Fred Miranda, for discovering the stair step interpolation. It works like this, when you enlarge or reduce an image, rather than just jump to the final amount, scale it up or down at 1. You will see a marked improvement in your image sharpness and final quality IF you are using CS6 or the older interpolation algorithms. However, on testing I have found that Preserve Details produces the same result as stair step and I hazard a guess that some of that is built into the newest algorithm. This was one of the unsung heroes in the first release of Photoshop CC.
