Picture size

[kenny]

I'm pretty good with a camera, but not with computers.
Size can mean two things:
1. The the pic's file size in kb or mb.
2. How large, in inches, the pic appears on the screen.
(Actually since screens vary from several feet to a few inches, phones, maybe I should express visual size in terms of full-screen, half-screen, quarter-screen)

Note, I'm not talking about sharpness/resolution, often expressed in DPI, or dots per inch.

I know how to control #1, but not #2.
Often pics I post are full screen, which is annoying to me and I assume to others too.

Also, I think exactly how you accomplish visual size varies with your computer, apple vs. PC, and the software of the forum you are posting the pic in, and perhaps the browser you're using.

I have no idea why my pics are sometimes too large, or small.

How do I control how large a pic appears here, using the following? ...
1. An 27" iMac desktop with the latest system software.
2. My browser is Safari (always kept up to date) and I'm not open to changing to another browser.
3. Pricescope's forum.

I have a very similar set-up at home. To me (in Firefox), it looks like all photos on this forum appear the width of the "posting window." When I click on a photo to get a better look, I actually want to see a big, high-res image (sample thread: "What is this tiny spot in my gem?" ) so what you're already doing sounds fine.

I think you are correct -- and I'm not an expert on this -- that the on-screen image size will track with native monitor resolution and not monitor size. So it's hard to predict how it will look for a "typical" user.

I never go to this site from my phone (or when I don't have good WiFi) so that may be a very different user experience.

I resize to 500-600pixels on the longest edge.
It will work well for pretty much anyone.

Karl, would you say that result in it appearing full-screen, half-screen, quarter-screen, eighth-screen?
... or is it impossible to answer when the question is phrased that way?

depends on the devise and browser.
That makes it near full browser window on a low end 780p laptop.
Just about right at 1080p
On high resolution screens over 1080p the browser scales the images up anyway most of the time.

 

[Karl_K]

To figure out what part of a screen it might be without scaling:
1080p is 1920×1080 pixels
768p is 1366x768 pixels.
Then you have to subtract the task and the browsers bars from that to get browser window size at full screen.

At higher resolutions and pretty much all phones the browser is going to scale them so you can not know how much screen it is using.

Thanks Karl.

I'm gonna chew on all this later when I have time, and post test pics.

@kenny, please don't resize your photos, or do anything that would decrease our viewing resolution!

You, of all PS regulars, take such astonishing photos of your gemstones... I truly want to see them as large as PS will allow, full-screen, and I know I am not the only one.

Aww shucks, thanks yssie.
