I only have a MacBook Pro with me and the pictures look good - wither directly in Microsoft Edge or in Preview.
I did re-run your pictures through a 300dpi dither filter. Maybe this is causing some issues, too. Both of your pictures look ok to me.
Then your MacBook Pro must have some amazing image scaling built in.

I've uploaded the 'small' version with the latest 720p pictures. How does it look for you now?

At 100% zoom, that image is about 140 pixels high. At what zoom do you expect people to read the document? Fit page width? Fit page height?
It feels like we're trying to implement mip-mapping.

My initial idea was (and still is) a printed manual as primary outcome. I absolutely also want it to be looking good when viewing on screens. On my MacBook Pro it shows the keyboard at 100% zoom with 840 pixel width (at 144dpi). The normal screen DPI should be at around 72 DPI and then it should be 420 pixels.
But these are numbers ... I can increase the size of the picture to the full width of the page (97mm), but as we are doing pixel work here I don't know if that looks good enough. Any ideas, how I can improve it for screens?

I think Firefox is to blame. It seems to do a poor job downscaling images in a PDF document. Firefox on the left, Edge on the right.

I have updated the Manual (both sizes) with a few more items and photos:
http://linux-tin.org/ModelFManual.pdf
http://linux-tin.org/ModelFManual-Small.pdf
I also received some wonderful updates (from depletedvespene and others), which I am reviewing at the moment and probably upload over the next days.
I am back home from travel, so I can do the requested measurements also ...
Thanks so much, everyone for the input - keep the information flowing.
I also would love to
get some photos from your Model F variants. I have two pictures in the PDF of my XT and AT boards already, so you can see the approximate angle I shoot them of (Section 2.12 Photos of the Models - page 2-34 at this moment)
Models I own:
* Model F 'XT'
* Model F 'AT'
* Model F122
* Model F107
* Brand New Model F62
* Brand New Model F77
* Model F 'XT Portable'

Ignore all my complaints about images looking bad. Every document viewer I have tried other than Firefox scales things down just fine.
Evince renders ModelFManual-Small.pdf quite well, but struggles with ModelFManual.pdf. The pictures you have in -Small.pdf now are fine.

Are you looking for photos which use the original layouts and keycaps only? For example, this is my Unsaver, which has the left and upper function/macro blocks replaced with the equivalents from an F122 keyset and is ANSI modded.

I have uploaded the latest version to
http://www.linux-tin.org/ModelFManual.pdf
or the size reduced version to
http://www.linux-tin.org/ModelFManual-Small.pdf
I have started with
Section 3 - Firmware Overview. For QMK I am starting to build the basics around its usage in the overview. During that part, I am building the advanced section around the firmware at the same time. There is some jumping around required over the next days, but everything is linked together in the PDF.

Just uploaded the daily changes. This time it includes the most basic version on how to get the QMK image to a Xwhatsit controller (Section 3.3). It assumes that the source code has been merged and commit to the QMK main repository, but other than that it should describe the process in great detail.

I just uploaded a few updates, mostly corrections and cosmetic adjustments of the QMK Firmware Overview section. I also added the translation table in the Appendix B for IBM Set 1,2,3 and USB scancodes.
93 pages for both:

Most content for the overview section has been added and I am starting to work on the sections that go more into depth. Obviously, there is still some outstanding work on everything and I am happy if someone wants to review it - especially the Firmware Overview section (sorry, the whole thing already counts 100 pages):
What I am still looking for are the
different variants of the Model F keyboards (2-21f). I already have 10 in there, but I am still looking for:
- System/23 Datamaster Monoblock
- System/23 Datamaster "Bezelmaster"
- CS/9000 Keyboard
- Model 200 '4704' - F62 Kishsaver, Original
- Model F Displaywriter
- 'Blue Button' Model F variants
- F127, 4980 for IBM Series/1 minicomputer
The document will be released under a Creative Commons license and in case you are sharing those photos, you need to be ok with me displaying those into the document under the same license.
Any help would be much appreciated.

Quick Update
Started with the
Hardware Details section; specifically the Key Installation. Taking a lot of pictures with different keyboard variants at the moment, but I thought I already upload what I have with the Brand New Model F Keyboards.
As always, latest version is available at:

I am working on
Hardware Adjustments and Troubleshooting at the moment. I'd love to hear what I should cover in the manual. This week I have planned to work on Disassembly and Repair Guides but that will span across several more weeks I assume. Anything that can be packed into a Technical Reference Manual is welcome.

The latest version uploaded to the location above received a lot of changes (in Section 4). It is still work in progress and just a sneak peek into what is coming in that section.

This is such a cool project. Kudos! I see you've already got pictures of a battleship, but would you be interested in some of one with original german/APL keycaps?
