Does changing the PPI really increase or decrease the image quality? How is DPI different from PPI? What actually is Resolution? In this lesson, we will answer all these questions, understand the difference between PPI, DPI, and Resolution, and delve deeper into what they actually mean with the help of fun examples, experiments, and a little bit of math. I hope you enjoy this video. Thank you so much for watching :)

I just went and watched this video. Two things came to mind. 1) I remembered how math has always made my head spin. I watched the first two minutes twice and could not follow what he was talking about, even though he has a nice presentation. 2) I'm so glad we don't have to know or deal with any of this to make great prints.

Lightroom Print has a ppi setting. (mine is always at 360. I never change it) There is no DPI setting anywhere in the print setting chain. I don't even know what that is and I have been printing for thirty years. This video might explain it but it is not really something you need to know. Some people might want to know, and that's fine, but it is numbers and math that don't really concern digital printers (most of us) working at home with our Epson and Canon printers.

Just for fun I changed my ppi from 360 to 150 and printed a small section crop on a 17x25 print. Looking at some very fine detail the 150 setting was not a sharp. So now we know that changing the ppi does effect quality of the final print.

Choosing the Perfect Print Resolution for Your Photos
Posted: 02/05/2024

Creating high-quality prints of photographs involves numerous considerations, with one of the most critical being the print resolution. The print resolution, measured in dots per inch (DPI), determines the level of detail and clarity of the printed image. The optimal DPI setting depends on various factors, including the purpose of the print, the viewing distance, and the capabilities of the printer. In this blog post, we’ll explore how to choose the right print resolution for your photographs to ensure the best quality.



Understanding Print Resolution

Print resolution refers to the number of dots of ink a printer can produce within an inch. A higher DPI means more dots per inch, resulting in a sharper and more detailed image. However, the effectiveness of high DPI values depends on the printer’s capabilities and the quality of the original photograph.


Standard Print Resolutions

Low-Resolution Prints (72 to 100 DPI): Suitable for large banners or prints that will be viewed from a distance. At close range, the image will appear pixelated.
Medium Resolution Prints (150 to 300 DPI): Ideal for standard photo prints, such as 4×6 inches or 5×7 inches. This range provides a good balance between quality and file size.
High-Resolution Prints (300 to 600 DPI): Recommended for high-quality prints, especially for professional photographs or detailed artwork. This range is often used for prints that will be viewed up close, such as portrait photographs or fine art prints.


Factors to Consider

1) Purpose of the Print: Determine what the print will be used for. Decorative art pieces or professional portraits require higher resolutions than a standard photo album print.
2) Viewing Distance: Consider how close viewers will be to the print. The closer the viewing distance, the higher the resolution should be to maintain image clarity.
3) Printer Capabilities: Ensure your printer can handle the desired DPI. Some consumer-grade printers may not print effectively at very high resolutions, leading to wasted ink without a noticeable increase in quality.
4) Original Photo Quality: The resolution of the original photograph limits the print resolution. Enlarging a low-resolution photo for a high-DPI print can result in a blurry image.


Recommended Resolutions by Print Size

Small Prints (up to 5×7 inches): 300 DPI is typically sufficient for clear and detailed prints.
Medium Prints (8×10 to 11×14 inches): 300 DPI is still recommended, though you can sometimes get away with a slightly lower resolution if the original photo quality is high.
Large Prints (larger than 11×14 inches): 200-300 DPI can be adequate, especially for prints viewed from a moderate distance. For very large prints or banners viewed from further away, 150 DPI might be sufficient.


Recap:
Choosing the right print resolution is vital for producing high-quality photographs. While 300 DPI is a good standard for most prints, consider the purpose, viewing distance, printer capabilities, and original photo quality when determining the best resolution for your needs. Experimenting with different resolutions and print sizes can also help you find the perfect balance for your specific project. Remember, a higher DPI isn’t always better; it’s about finding the right setting for the desired outcome.

My old printer (Epson 2880) gave me a choice of something: 1440 or 2880. It didnt make any difference to the final print which I chose. The final prints were identical. Epson has now done away with that and there are no choices for whatever that was about on my current printer (P800). In my software (I print through lightroom) I set the PPI to 360 five years ago and have never changed it since. My choices now have nothing to do with PPI or DPI or 1440 or 2880. I determine my final print size, 5x7, 13x19, 17x25, whatever, and my paper profile and print.

You haven't needed to bother with the math of it for years and yet this topic rears its confusing head a few times year after year. All the computer power we pay for and all modern programs we use will do it for you. Don't bother with this stuff. You will only end up wasting time doing something your computer does anyway. Choose a ppi that works for you (360 is the Epson default) set it and forget it, then print whatever you want.

When you misplaced it, it was probably a crime to have it. Now you can just go to a store a buy it. How things change.

This made me laugh. It made me think of all the years where the first thing you did when opening one of the plastic ones was to smell it.

Eventually the metal cans were replaced by plastic.


When they went to plastic Kodak made all theirs black but some of the other film company's made their's clear which was nice when you wanted to know what film was inside. I would often tape the label from the box to the can to keep them sorted in my camera bag. Then, of course, there was German customs. You couldn't have your film in bricks. All rolls out of boxes and out of cans. Before going overseas I would put a rubber band around each roll to keep things neat and to keep the film leader from sticking out. Seeing those cans brought back lots of memories. I still have two. One with tiny little nails in it and the other with a few rattlesnake rattles in it.

I don't mind, and I won't have an iPhone.....


I'm just curious. Do non Apple phones automaticly sync with computers if they are looking at the same online storage? I've just assumed every phone on the same account or network would auto sync something like Photos without having to do anything once the system is set up. Don't calendars and contacts talk back and forth between devices? Mine do. Wouldn't photos be the same?
Not trying to make a point here, just wondering.

An old subject with many preferences from each one of the readers. I find the usb cable more reliable in my opinion , opening the camera door and taking the card out it could very easily be scratched, and then replace it back in the camera, those are few steps more than plugging the cable into the camera. Some saying something about running the battery low, this could happen as we taking photos. My usb cable is always plugged into to my computer, not a big deal!


I didn't know scratching a card was a thing or even possible. Never heard of it happening or even how you would do it.

Why would anyone use a card reader when there are more direct ways to load photos onto a computer, like using a USB cable?


By the time you pry open the rubber door on your 7200 and insert that annoying little plug into the slot, my card reader is downloading files into the Lightroom folder I download to. And even assigning a few keywords. It doesn’t get much easier than that.

I go to the photo directory in the phone and copy the images to the computer. Easy.
The phone is always on during the day anyway.
I have a spare phone cable next to the computer.

So old fashioned. When I take a picture with my iPhone, which I hardly ever do, it magically appears in the Photo folder on my computer. I don’t have to do anything.

All these are favorite spots. Been to Orkney four times and looking forward to the next trip. We rented a house on Skye a few years ago. Found that about five or six days to explore felt about right. The drive along the coast, North and South as far as you can go is great. Long ago one side of my family came from Scotland and I saw my name on many signs. That was kind of fun.

I found that it was a real wrestling match to rotate my Nikon 80-400 to shoot a vertical so a tour leader told me about a Kirk foot. Go to kirkphoto.com and look for NC-80-400GN. I ordered it the day I got home and what a world of difference! My lens rotates very easily now. Good luck!


Me too. Kirk feet on everything. Quick and secure.

This image is from Scott Wells...He uses a Nikon z9 with a 600mm lens...I have a Nikon D850, D500, and am using a Sigma 150-600 lens...is it every possible to get this level of sharpness without a mirrorless camera and a prime lens? These images are amazing...


Sharpness comes from the lens. A great lens has to ability to give you a super sharp file. Focus is a combination of the lens and the camera working together. People here have talked about newer cameras having eye focus. To me, that could be really nice but it still comes back to the lens. Focusing on the eye with a less than sharp lens won't give you a sharp shot, just a better focused shot.
I am not a fan of the example photograph. The top of the eagles head is over exposed. I live in a land of eagles. Sitting at my computer and looking out the window to my left I can see two eagles sitting in our eagle tree. Everyone around here photographs eagles. Most eagle pictures have an over exposed head and that fact makes the shots that are perfectly exposed the winners. Mr. Wells might have detail in the head in the raw file but by opting to wipe out any hint of sky has blown out the head.
I have never seen a real sky this white. It makes the shot look over processed and the eagle seem to be pasted on a white background. Yes, the picture is sharp but it is missing other things that it needs to make it amazing. I can't get past the white sky and the blown out head. To me the cropping also feels uncomfortably tight. The eagle is nowhere.

Sharpness is just one aspect of an amazing picture and most of the others are missing. Re-crop, bring down the highlights (and whites) to give this eagle someplace to be, and this file might be amazing. Don't get too hung up on sharpness. I would trade a little sharpness for an an eagle shot with a little more dynamic interest. It is sharp though.
