That pizza analogy was so good and really hit the hammer. Kudos

Thank you! Be sure to take a look at the videos I've released before this one. They all are part of the same Digital Fundamentals series, and each is a wealth of information. 😜

Truly excellent - thank you! Liked and subscribed!

So much research is done on these videos. Like and subscribe everybody.

Hi. I want to buy a scanner to scan many photos and my question is: more DPI = more quality ???????

[@TheArtofRetouching]

I'm sure someone will disagree with me (because, you know, internet) but they lie right on the box by saying 48bit, when that breaks down to being 16bit CMYK (16x4=48bit). Optical quality matters so much more. My scanner is 19 years old, and it's not like it's garbage, right? I see Epson has a v600 which is a throwback to a model 600 I had like 25 years ago (which was 17"x22"). It's only $230, so I say get that one, as the $1200 v850 may be a bit costly. I would say stay away from Canon, as all of theirs are under $100, which means the quality is likely not there. In fact, I may just pickup that v600 to see how well it does.

Great info! I just wish the designers I was working with would understand this. Do you have any presentations about how to make images for really large prints for wall murals? 15' to 40' in size.

love the show but what i am looking for is a comparison of inkjets under $300 and which provides the best resolution. I am trying to buy and cannot determine which is best. any chance you do product comparisons and define which item produces the best quality pic? thanks!

[@TheArtofRetouching]

Thanks for asking. It's pretty easy to pick, as these days the Printer landscape is pretty barren for innovative products. As with Scanners, nothing new worth a damn is coming from either Epson nor Canon. As such, first I recommend Epson Expression Photo XP-970 as that's the only current 11 x 17 model. It still uses the same ink as my printer from 13 years ago, that I still use. It's also within budget. Please note: It SHOULD support papers of 13 x 19, but it doesn't, which is garbage. For that, you need to go over budget at $350 for Epson Expression Photo HD XP-15000. Only one more option left, is to go with Canon PIXMA iP8720 at $250 which is more reasonably priced with 13x19 paper support. Though, I've never owned a Canon. I would not even consider any other current models that I did not just mention. Other brands like Brother are more in the Laser Printer industry, and less in the Photography Printer industry.

Lower resolution can and is better than higher

[@TheArtofRetouching]

Alright, I'll bite.... Why?!?

[@thedarkslide]

Equating resolution with pixel count is problematic. Why? Because all pixels are not created equally when taking an image. A camera with a color array filter featuring a 24MP sensor will resolve less than half the details a camera with 15MP without a color array filter (like a Foveon camera or a black&white camera) can resolve. My Sigma sd Quattro has a nominal pixel dimension of 20MP but it easily outresolves the details my 50MP Canon 5DsR can take. The resolution of a camera system should be measured in how many line pairs per mm of capture area it can resolve. My other comment on this three year old video: the statements on upscaling images are now basically outdated. With AI based upscaling, you can blow up older images to insane sizes without noticeable image quality loss.

why does he look realistic
