When you post a photo on UHH and click 'save original' and;

a UHH member/viewer downloads the 'saved original' and;

the viewer clicks on the small magnifying glass with the + sign in it and;

the photo is enlarged.

How much is it enlarged?

Full size (100%)?

More?

Less?

Not sure, not to pixel size for sure. May depend on the computer concerned. Admin should know.

I suspect it is one pixel in the photo to one pixel on the screen - (not sure.) I know that when I'm looking at a photo using windows photos and click "view actual size" on the photos menu and then upload that photo to UHH, click download and enlarge it, they are the exact same size on my screen.

Depends on the size of the uploaded image.
Some just get a scosh bigger, some REALLY get bigger, some don't change.
(I've not desired to look at the details for each image.)

The image will initial open to either the dimensions of the image or the dimensions of the screen, whichever is smaller. So, an image at 600x800-pixels opened in a screen with size 1920x1080-pixels, the image will not fill the screen and will display at 600x800 where the pixels of the image are 1:1 to the pixels of the monitor.

Consider a larger image having a 3:2 ratio and sized to 2048x1365-pixels. If this image is opened on a widescreen monitor at dimensions 1920x1080-pixels (a 16:9 ratio), the image will initially be scaled to the size of the monitor, scaled to and filling the 1080-pixel height of the monitor and scaled slightly smaller than 1920-pixel width of the monitor, hence the black bars on the left and right of the 3:2 image on the 16:9 ratio monitor.

What happens next depends on the software being used, but if you only have one "1-click" to zoom, that zoom will be a 100% crop of the image at the dimensions of the window / monitor. So the example image above at 2048x1365-pixels would yield a crop of 1920x1080-pixels with no blank space on the sides of the image at a 1:1 ratio (one to one). The pixel dimensions of the image (2048x1365) are both wider and taller than the window when viewed at 100% or 1:1, so some of the image is cut off from display on all sides (top, bottom, left and right). You can use your scroll bars to move around the image to see the 1:1 pixels of the image on your monitor.

Some display tools will let you zoom beyond 100%, but the simple + / - 1-click zoom is from "full screen display" where the image is scaled to the size of the screen to the 1-click "100% zoom" where the image is displayed 1:1 in the pixel dimensions of the monitor.

An image sized exactly to 1920x1080-pixels when viewed on a monitor with dimensions of 1920x1080-pixels will display initially at 1:1 with no scaling needed.

Good explanation C_C.

thank you one and all.
