Image Resolution Tutorial Basics - TV, HD, 1080, 4k, 8k, Megapixels, PPI, DPI!

Learn the basics of device & image resolution in this image resolution tutorial. We'll look at some of the jargon around the industry and learn how physical device resolution is calculated all the way down to raw pixels. Learn some common aspect ratios and what a 'megapixel' means. We finish things off with learning how to see what the image resolution is in an Adobe Photoshop document, so you can properly prepare digital assets for export or on-screen viewing.

Amazing explanation. Thank you for your work!

I was confused with the mix of industry jargon that's used regarding TV screen resolutions; 1080p vs. 4K as an example with each referring to pixel counts along different axis' as you'd pointed out. I'll start calling 1080p "2K"... so there!

This was far and away the most comprehensive explanation regarding resolution. Thanks!

Thanks for the great tutorial! you explain confusing concepts in a simple way.

For printing what is the best format for saving a photo file, jpeg, tiff, png... etc, thanks

This is incredible, I am doing full stack engineering, and want to understand the front-end thoroughly.
What I would love to know is how the physical pixels the actual red/green/blue hardware pixels map to screen resolution pixels ?

[GerritforBazeja]

good to know how this works. Nice explanation, thank you

[jessedt]

This was the best tutorial to learn about image resolution. Great job!

[rizkgerges]

you can also push the right click on the ruler and change directly from inch to pix or cm without going to preferences. just faster :p

If I want to play image on 16k resolution tv .Then what megapixel professional camera is required to capture the image so that it will be right fit for 16k television..

But higher resolution, explained simply, does it not mean more pixels over a standard area, as with dots per square inch. And if so, what is the standard area over which pixels are measured? Is it not per square inch.

[WebVid]

In mirrorless cameras, viewfinder screen resolution is referred to in millions of dots. Why can’t we just use screen resolution units?

Thanks for the video, it is very helpful!
But still I have a question - in example: If I have a photo camera with 42MPX sensor, and then i want to create JPG from RAW, how can I know what is the largest possible DPI during exporting, to not have to create an additional virtual pixels. In other words, how to connect the MPXs of the camera with PPIs. I made an experiment, and exported the same RAW photo to JPG as 300 PPI, and also as 72 PPI (and also as 10PPI), but with the same picture dimensions. I thought, that when I will enlarge the photo on the screen, the 72PPI will be much more pixelized than 300PPI, but, what surpirised me, after zooming the JPG they had the same amoun of pixels and they were exactly the same on the monitor.

[serhiikichuk]

Very clear explanation. Thank you so much!

[azeezalshebli]

My phone resolution is 1080 x 2340 so how it means

[swingoutmuseum]

I'm a newbie and I learned a lot, thank you.

[timlong]

Seems like ppi is by far the best way to show resolution for all screens. It actually tells you resolution without doing the math.

[elmag]

Please tell me 1366x768
It's is an 720p or 900p or 1080p

[hamodeyDooba]

Voice clear better than last videos

Could you do tut how to do, star rating system

[mbaceo]

1080p is GOOD for under 60in TV ... wish MORE RND went in COLOR & UPSCALING than 8k size

[rockonmadonna]

So, let’s get this straight, please. The MacBook pro is only 220 or 226 ppi. That is not even Full HD, right? So playing video that was shot in 4K or even full HD on the laptop is pointless, right? Thanks.
