Image analysis on which medium?

Monitor, smartphone, or tablet – it makes a difference

I'm curious to know what device you use to view the images here on the blog.
Specifically:

Smartphone?
Tablet?

PC monitor (size in inches)?

Up until now, I’ve only commented on images after viewing them on a monitor.
Lately, I’ve been a bit lazy and have done this on my tablet.
I noticed that sometimes an image looks technically flawless on the tablet,
but when viewed on the monitor, it might show issues like color banding, noise, or other imperfections.
Of course, this can be explained by the difference in display size alone. Additionally, different viewing programs interpret images differently,
and photoclub might also apply some adjustments.

Why am I interested in this? It could help us consider how to resize and possibly sharpen images, and what size (pixel dimensions) they should be uploaded at to look their best.
Best regards, Cornelie

then continue to check out my photos on the tablet :), but take a good look at the others on the PC monitor. Just kidding—I actually only view them on the PC monitor. I don’t have a tablet, and using my phone makes me nervous; I can’t really see well :-) When it comes to size, size definitely matters :D I use 1920x1280. Cheers!

Hi Cornelie, I usually use my PC monitor because it covers 99% of the color gamut and has excellent contrast, so for me, it serves as a kind of reference.
I only use my tablet when I'm on vacation or want to show someone a photo, just like with my phone.
PS. I always save my photos at the highest JPEG quality.

...I'm a bit old-fashioned: a 27'' monitor. I don't own a tablet, and my smartphone is strictly for work purposes—communication and occasionally snapping a quick photo of a document on a construction site or something like that. Since my images, especially the newer ones, are larger than the limit here, I sometimes have to compress the JPGs down to 95% or even 90%.

Thanks for the initial posts.
@Ulf Simon: What’s the maximum image size? I haven’t been able to find that information so far.

@Cornelie Pflüger
I'm not the Ulf you were directly addressing,
but I seem to remember reading that 7MB is the maximum
— I just can't recall where exactly.

10 MB — the upload setting complains if it's over that.

Thank you, Ulf.

That was kind of a side effect of my original question.

I’d like to understand how the medium through which you view images influences whether you find an image appealing.

I view photos both on my computer and on my phone, depending on what’s available. However, I’ve never been able to zoom in on the photos—neither on my phone nor on my computer. Could someone help me with this? I always upload JPG files, and for a while now, I’ve been using reduced resolution. That way, they take up less storage and are still good enough for viewing on a computer screen.

I always view digital images like these on at least a 27" monitor or larger.
The iPad is, at best, a temporary solution for viewing on the go.
However, I prefer to see my own photos printed on high-quality, suitable paper, as the impact of a "real" print is quite different from a fleeting image on a screen.

@Cornelie Pflüger
The medium itself only affects an evaluation indirectly. With higher resolution, you see more details, which can have either a positive or negative impact depending on the artwork

Joke’s over! Of course, you can’t properly assess an image on a tiny mobile screen the size of a postage stamp.

In my later years, I'm just a hobby photographer, so my 23.62-inch monitor is more than enough for me.

@Cornelie Pflüger which part of the message do you agree with????

If you're unsure between two options, then we should choose the bigger (picture).

‘then I continue to look at my photos on the tablet

, but I carefully check out the others on the PC monitor.‘

I like your joke and agree that it’s better to view them on the PC monitor.

@M B I usually resize photos using Photoshop, but I quickly checked online and found several free websites where you can do this as well, like this one: "https://www.fotovergroessern.de/" Hope this helps you out...

Alternatively, you can of course use free, open-source tools. Most of the time, you want to resize an image before uploading it. This works great on the command line with mogrify (available for various operating systems as a free download and offering many other conversion options, like changing formats from jpg to png, etc.)
mogrify -resize 50% rose.jpg

You can also do this for all images in a folder at once:
mogrify -resize 256x256 *.jpg

For tasks like these, there’s no need to shell out for Photoshop or similar software

.

To answer the original question: Some photos do look better on smaller screens, like a smartphone display, but to really appreciate the details, a larger screen is preferable. Personally, I find viewing a printed photo on the wall even more enjoyable

.

Best regards from me!

I only view the images on my PC.
Primarily because of the image size and color contrasts, although of course every desktop displays an image differently.
There’s quite a range, from Eizo to LP-Power and Dell.
Most monitors are 27 inches or larger.
I rarely look at images on my phone when browsing the forum.
Nowadays, there are plenty of programs available for resizing.
I mainly use Lightroom or Neo.
