How Pixels, DPI, Resolution, Picture Size, and File Size All Relate

[@askleonotenboom]

Size and size are two different things. Confused? I try to sort it out for you.

[@9ijnht5rdx]

I done loaded faststone and right clicked and the box that opens doesn't have the same selections as yours. What gives?

[@askleonotenboom]

@@9ijnht5rdx Not sure. FastStone has several different programs. I used FastStone Image Viewer, version 7.5

[@justanoob7030]

Very comprehensive. Thank you for taking the time to explain this so clearly.

Penny deserves all of the DPI, megapixels, megabytes, and resolution you can give her. :) Great video. Cleared up fuzzy spots in my understanding of how picture properties are calculated and measured.

[@lynned.5491]

Thank you so much. I have been trying to learn this stuff from many, many other videos but to no avail. Your teaching was clear and understandable.

[@liveandlearn11]

Great tutorial. I really appreciate it!

Great video, but I'm confused in that you lost no resolution from cropping, but why doesn't that translate in video as well?

[@raymondfdavey]

I also wondered about this. After watching a few other videos I think I understand it - although happy to be corrected. It is true that the cropped image has 'not lost resolution' in the sense that the actual section that was cropped has the same level of detail/information in both the original and the cropped image - if you were to zoom in on the dogs nose in both it would look the same. In that way that section's resolution is unchanged as it is just the same info but without the surrounding info which is chopped out. However, it is confusing in terms of viewing the cropped image because in the example it has been expanded on the screen to the size of the original image, so in the commonly used but separate notion of 'resolution' of an image in the physical world (usually given in terms of pixels per inch or similar) it HAS lost resolution as the cropped section has been stretched on the display to fit the same physical space as the original - less image-pixels are being used to fill a larger physical space on the screen. But this would be the same if you zoomed in on that section on the original so it occupied that space as well. So I think it is simply two different notions of the word 'resolution' causing the confusion. I think I might have made things even less clear with my explanation and in case so; then this video helped me understand the distinction: kzbin.info/www/bejne/aqPLh354pZl5m5Y&ab_channel=DaviesMediaDesign. Ps just wanted to add thank you so much leo, I really found this video incredibly useful for my studies and so thank you!

Thank you for this information, Mr. Leo!

Thank you. Do you also have a video on how to make a photo larger. So you can print it. Say you have 1920x1080 but the printer company demands 12 mpxl photos?

[@taair6270]

Great video and explanation. but I’m struggling with a problem. I’m trying upload images to a stock photo site. the problem is there is a criteria that you need pass first. the images you upload need to be uncompressed (opened) and need to have a file size of 17mb or lager. so how do you know what size that needs to be in pixels to (aspect ratio etc) to equate to that file size in mb. is there a “formula” to do this? rather than randomly playing with numbers (which is very frustrating! 😖)until you get something near to it? Cheers

Screens are never measured in Dots per Inch. Dots per Inch only applies to printing.

[@austinharding9734]

so DPI is a setting of the screen or a setting of the image? will all images on the same screen be a certain dpi or will all screens on the same image be a certain DPI?

[@rocknrollcanneverdie3247]

then why is every 1080p screen not the same aspect ratio?

[@askleonotenboom]

True 1080p is. 1920x1080, aka the 16:9 ratio. If it's not 1920x1080, then by definition it's not 1080p.

[@codex3048]

1:18 Isn't it confusing to call a pixel a "dot"? Pixels are square. Dots are round. If the terms were synonymous, then there would be no reason for having separate terms "PPI" and "DPI."

please help me can i recover google password forgot it dont have recover email

[@askleonotenboom]

Follow the account recovery or lost password steps as offered by Google. If the recovery process doesn't work for you -- maybe you don't have the recovery email or phone -- MAKE SURE to follow the instructions CAREFULLY and COMPLETELY. If the recovery process can't be made to work, and there is no customer service (common with free services), then I know of no way to recover the account. If that's your situation I'm very sorry. Regardless of whether you recover the account or not, I would encourage you to review the steps outlined in this article to avoid it ever happening again: askleo.com/a-one-step-way-to-lose-your-account-forever/ Good luck!
