You can see on the screenshot: it's based on the digic6-dumper branch.

my best advcie to you is buy an arduino nano or uno (both are arm processors)

None of them has anything to do with ARM. They both utilize ATmega328, which is an 8-bit AVR microcontroller.

Fully agree with the rest of your post though!

M50: worked out of the box
70D: took me some restarts and card swapping before it worked, in the end without ML card inserted. AF was not available at all. But I didn't spend more than 2 minutes for trials here.
M: no success at all, even without SD card, with non-bootable SD card, auto/photo/video mode...

I'm not a programmer: Funny thing (IMO) they managed to get a clean USB output but keeping cam's liveview display active including overlays. Looks like USB is able to do a bit more than we knew.

Well, it's not that new. In 2008 I played a bit with Canon EOS SDK (Software Development Kit -> some libraries for interfacing EOS cams from PC programs) and it was already possible to get clean output over USB from EOS 450D. So it would be also possible to use it as a webcam at that time, if someone knew how to redirect any video stream to something, what Windows (or any other operating system) is able to interpret as a webcam. I didn't and also had no use case for that. But it's doable for any software developer, without reverse-engineering.

There is absolutely nothing rude or impolite in heder's response. It directly answers the original question and does even more: precisely points out what is needed to achieve the goal.

The new guy totally overreacted.

However, I and a few others could probably work on polishing our welcome kit  .

Yep, fully agree. But heder is not that case.

Sorry, dislexic keyboarder here, I meant FPS and have modified the original post.

Please, refer to my post from March 2019. I've enabled this feature on 70D. It still has some quirks but is IMO usable. The download link is there, check it out.

Unfortunately no time to continue working on it.

What is FFS?

Very well written introduction. I'd only like to correct this detail:

You'll need to get booting enabled on your cam.  This is a small, persistent change to firmware (a bit flip in flash, I think) that instructs the cam to try and do a firmware upgrade if a .FIR file is found on the card.  This is a one-off task, find the magic firmware for 6D2, somewhere earlier in this thread I expect.  ML hijacks the firmware update process to inject into the running OS - but note that no persistent changes are made; there's no firmware update, it's just how code gets injected into ram.

It's slightly different. ML hijacks the firmware update process only in two cases:
1) ML "installator" to enable the boot flag
2) portable ROM dumper runs fully in this mode

Activated boot flag instructs the cam to look for autoexec.bin on a memory card at every boot and, if found, execute it.

You won't be able to create a working *.FIR until you sign it with a proper key. This key is not made public. You have two options: ask a1ex for an updated boot-flag-enabler or dig in disassembly + RAM dumps to find it on your own.

From what I understood, we can have 1832*1024, 23,98 continuous in 12 bits lossless right ?

I was personally always recording 25 fps so far but 23,98 is just a setting from the Canon menu, which should work same good. So: yes.

Does DPAF works with these settings ?

Yes.

Is it stable ?

From my experience: yes.

Does a VAF-7D also works with DPAF ?

Never had one but I expect: yes. VAF only blurrs the image. Nothing less, nothing more. I don't see any reason why it should interfere with DPAF.

Hi Walter, any news from your side?

I've just started getting familiar with my FIMI X8 SE. The plan is also shooting stills and recording short videos during holidays. I have a feeling one definitely needs practice to achieve best results but in a nice place with a good weather even a beginner (but with a strong photo/video background) could get good shots.

You should be hired and making money in Hollywood for such shots/colors/grading..... this was amazing

Look at his other videos. On some commercials you'll see "Paul Heran -- Director of Photography".

I apologize, I was reading too briefly and didn't get that you talk about something not related to original post.

I do personally not care. DSLMs are so silent and shake-free in comparison to DSLRs, that I simply don't mind the shutter at all. And will rather change the cam before the shutter wears out...

No, M50 has full manual exposure in movie mode and supports both 25 & 24 fps.

I would guess it has something to do with the composition. Example: the horizon should normally not be placed ideally in the middle of the frame but rather 1/3 or 2/3 of its height (or maybe golden ratio). To satisfy this rule for all formats, it requires matching the position of 1/3 of their height, not their centers.

Think these will work:

Disclaimer: no idea if the addresses of frame shutter blanking times are constant or camera-dependent or maybe even random at power-up. I also didn't test them as I didn't know how.

As of now i hv two builds in two different cards. One is build by Arczipl. This build doesnt seem to work the uhs sd hack in my initial test so i replace with danne's ush sd hack that run with lua script.

It works for me flawless. What do you do exactly?

You have to go to Debug menu and activate it manually. Combining my build with Dannes autorun script won't work out of the box, as they were not meant to work together. However, you can adapt the script easily -> just replace the menu option name "MAY CAUSE DATA LOSS" with "160MHz fixed". That's what appears in the menu, to easily distinguish which version is loaded.

If anyone interested, I share some more impressions:

Picasa
Really good face recognition. It needs more user input than Microsoft Photos but the end result is also way better (more recognized faces). Amazing to see how the detection algorithm adapts decisions after every single user action. It's also great to have an option to just don't tag particular person. Just give this feedback and the tags for this person disappears. Great for some school photos or trips with people in the background I don't even know.
It offers tagging and so on but, typically to Google apps: they implement just one way of doing things and leave nearly no configurability. This I don't like a lot. Example: tags are always stored in metadata of JPEGs, so my automatic backups would explode.

ACDSee Studio
Also a very good face recognition. Beside that a lot of features, options, menus... A bit too much for my taste and important things are hidden. I was also not able to find e.g. multiple directory/file exclusion by masks. The statistics looked cool when shown on YouTube video but it's just a gadget. Can't really configure them. Also very bulky: it starts 3 processes. One main app, background indexer and something else, probably for synching with clouds? The last two stay on, even after you close the main program. Blah, don't like such stuff.


At the moment I tend to DigiKam, even despite the automatic face recognition doesn't really work. The rest ist just great.

Thanks for your contribution. However, as far as I know, IrfanView is just an image viewer, without managing/organizing functions.

Another one I'm just evaluating is DigiKam. It is very well designed, usability is definitely it's strength. It also satisfies all my important requirements with the exception of face recognition, which is just bad. However, manual face tagging is made in a very smart way. I like how it's philosophy greatly matches to my already available folder hierarchy. Next strength: it's cross platform. I consider moving away from Windows if privacy will be further spoiled like it already is and possibility to keep the tool on another platform is pretty convincing.

Next one to check out will be ACDSee Photo Studio. Based on videos on Youtube looks promising. Quite pricey though.

Hello, I'd like to ask you for a recommendation of a photo management software. My photo collection is so far organized in directories, named by sortable date + keywords. Pretty neat and tidy but as it constantly grows since 2004, it became barely searchable and hardly possible to keep an overview.

Despite never using a photo manager, I think I have some ideas what I'd like to have. While setting up a new laptop for my grandmother, I checked what the included apps can do. Microsoft Photos from Windows 10 was an eye-opener here.

What the ideal program should be/can:

• fully offline solution: photos stored offline (actually on a NAS in LAN), database stored offline
• face recognition, really working one, Microsoft Photos is here just amazing
• rating system (I mean, I can assign stars to mark best or worst photos)
• tagging photos by keywords, also by browsing the underlaying directory structure and doing actions on directories, e.g. adding tags to all photos within a directory
• possibility to view images on a timeline, like here:
  
  neat, tidy, space-saving, on the right you can slide to move between dates over whole collection
• filtering and sorting options
  example 1: show only photos with tags "(Norway or Sweden) and Winter", sort by rating
  example 2: show only photos of my wife (by face recognition) with tag "ID card photo", sort by time
• after selecting a certain photo from a collection I'd like to be able to either see it's physical location or open it in external program of my choice
• it should look neat, work fast, Microsoft Photo could be a benchmark here
• freeware/open-source of course best but a reasonable price for a private license is also ok, let's say... up to 100€ (?)

Nice to have details:

• possibility to exclude directories or files by some filters (ideally regular expressions), e.g. exclude all .psd, exclude all RAW-* subdirectories, exclude all *work*.* and *small*.* files; but if not possible I could re-think the folder hierarchy... maybe completely split RAW+working dirs from the final ones
• once the photos are scanned and tagged I'd still like to have a possibility to edit them (or rather replace, as this will be mostly newly developing from RAW to the same location as the previous file) with external program without loosing the tags
• would be good if also moving or renaming a subdirectory could be tracked without loosing the assigned tags
• the photo manager should not edit photo files, i.e. adding tags shouldn't be realized as adding data to EXIF -- this would screw up my whole backuping strategy

Too much? Ask Santa Claus or write yourself? It so, then I'll still happily hear about best what you can recommend.
Actually Microsoft Photos + tagging + rating + filtering would be already good enough. So it can't be that hard.

No editing options needed, have another tools for that. However, a nice simple full-screen browser would be nice. I use FastStone Viewer for that purpuse but I can imagine wanting to see all photos matching the filtering+sorting on a full screen.


I started looking for possibilities by checking which apps offer face recognition. Got a list, tried Fotobounce first. And it's such crap I can only imagine. Slow, screen-space-wasting, offers no better browsing options than just browsing my directory structure and face recognition is unusable. For face recognition they just simply compare 2D images, so only identical perspective, haircut, lighting conditions and so on lead to a match. There are much more advanced techniques already. Full 3D head projection, pose and expression neutralization... Microsoft Photos must use it.

Some background of my directory hierarchy: I split all photo sessions, holidays into separate directories named by a date (in a sortable form yyyy.mm.dd) + some tags. Inside I put a subdirectories: all RAWs, selected best shots in RAW, selected best shots postprocessed, selected best shots postprocessed for showing to others (without too private stuff or limited to let's say 100 shots of a holiday). Naming of these directories is always consistent. If needed I could move all final images to another location.

For viewing I use FastStone Image Viewer: fast, nice to browse through directory trees, awesome full-screen viewer. I believe I'll keep it anyway as standard browser for many cases. However, it has problems when switching from viewer to browser mode, while being inside a directory on a network drive. It hangs up or crashes often. It is also problematic to browse directories fast, as FastStone always load photos new to show thumbnails. This includes all subdirectories, also with RAW photos, which takes some time. Keeping the collection on a NAS makes it even worse. I like that it doesn't create any files inside directories but that's the price to pay.

Indeed, we can live with Bayer, but we should go always beyond.
I think more important than asking "how" to create better sensors is also "why".
(...)
I think people should ask those questions more frequently.

Generally I agree with you. But speaking for myself: I started my adventure with photography in 2004 with Olympus C4000 Zoom. A compact with pretty good IQ at that time, f/2.8 and RAW format with a hack. At that time I was very unhappy with the DR and noise performace. One had to use ISO100, ETTR perfectly and the DR was still too low to cover very typical daylight scenarios. Burnt-out sky and heavy noise in shadows were typical for outdoor photos. Cropping in post was not really cool as there won't be much left from 3,92Mpx afterwards. And the cam was also soooo slooow (especially shooting the 6MB RAW monsters ;P). Yes, this setup was limiting me. I was dreaming about super-high DR and also low light performace. Fujifilm Finepix S3 Pro with the special type of sensor consisting of S- and R-pixels for increased DR was a dream. Same as lenses f/1.8 and faster. I remember checking out some samples from the net and being amazed how much it was possible to recover from highlights.

With my actual equipment I am the limit, not my hardware. Especially that I hardly find time for photographing outside holiday travels. The HW is nearly perfect. Better cam won't make my photos better (with the exception of damn BF/FF using the phase AF in DSLRs, which in my case improved with 70D due to AFMA and is finally gone with M50). That's why I don't look what future brings. I have the HW which already is good enough. Just need to use it more and better.

BTW: after all the years I've just started reviewing and tidying up my photo collection few days ago, which was only growing in last 15 years. I didn't delete bad shots or shots I don't need anymore until now. There are also many sessions which were never converted from RAW. And seeing the photos from C4000Z: yeah, really decent cam as for 2004. The shots are still perfectly usable. But the DR is scary low. There is so small room for postprocessing... One can really see the progress of 15 years.

After downloading RAWs from the above mentioned linke, setting "all to 0", no sharpening, no denoising, white balance set on a gray card in the middle for each shot separately:
- sd Quattro H has an amazing sharpness and nearly no moire/aliasing artifacts. The text below the color checker is readable to the last line. Way better than D850 and 5DIV, despite much lower resolution of the final image (45 and 30 vs 25MPx).
- color checker looks virtually idenctical on D850 and 5DIV but sd Quattro H is very different. Blues, oranges, browns, violets are heavily affected. Despite I somehow "like it" (does it matter? or should the photo just match reality perfectly?), I don't know what is closer to real, as I can't compare it with the color checker itself.
- on sd Quattro H the blue channel is noisy already on well exposed parts (look at blues of the color checker!). I wonder how is it usable for landscape shots with a lot of blue sky...
- response curve is different; has to push shadows by +0,5EV to match exposure of D850 and 5DIV
- +1EV and the image from sd Quattro H already gets awful, large colored spots over the whole dark gray background. Mostly prominent close to image edges. Just with +1EV! For me, such a cam would be useless.

I can live with Bayer, for me it's a sweet spot. No wonder it's commonly adopted. No breath-holding what near future brings.


EDIT:
If someone argues about the choice of competitors: just checked the prices and ok, fine, comparing a 1,3k€ cam with a 3k€ might be unfair. Just take then 80D instead of 5DIV and D7500 instead of D850. The outcome stays same.

Noise and ISO are ok only at 100 - 200 and 400 and from reading how it works on dedicated forums it's because is like a camera with only 100 ISO film.
Changing it is just a "memo" for the raw processor to push up exposure in post, that's why it gives so much noise at high ISOs
But sharpness and details are great.

If noise is "ok only at 100 - 200 and 400" then the dynamic range is bad. Nikon, Sony and Pentax are also having so called ISO-less sensors, i.e. it doesn't matter if you dial in ISO 3200 or ISO 100 and push the file by +5EV in postprocess: the results will be the same.

I believe this comparison should tell all:
https://www.dpreview.com/reviews/image-comparison/fullscreen?attr144_0=sigma_sdquattroh&attr144_1=nikon_d850&attr144_2=canon_eosm50&attr144_3=canon_eos5dmkiv&attr146_0=100_6&attr146_1=100_6&attr146_2=100_6&attr146_3=100_6&normalization=compare&widget=645&x=0.1367195625070196&y=0.5167449200029397

sd Quattro H vs. D850 vs. M50 vs. 5D Mark IV. All with same subject, same exposure, ISO100 + 6EV.

Seems also to have a lot of potentiality in recovering highligts (at least).

If there is potential to recover highlights, then the photos are probably not ETTR-er. No surprise, as all DSLRs I know tend to underexposure.

Look at samples. The dynamic range (=> shadow noise) sucks. People like it due to its colors, not ISO performance.

There were another variations in the past from different manufacturers. Honeycomb instead of standard Bayer, additional fourth color and differently sized sensels to increase DR, to name just a few.

No experience here at all but check the offers of DJI. Once I thought about purchasing a drone and Spark was an interesting candicate. It is tiny, delivers decent quality, price/value ratio is quite good. With some mods it seems you can reach over 1000 meters altitude (but with such small drone and thus a small battery it doesn't make sense to go to that high). 1080p30 video with 2-axis stabilisation, 12Mpix stills. Unfortunately they strip it ouf of RAW format. To get it you need to grab much deeper in your pocket, at least with DJI products.

Hmm, now I see that 3k is already possible without FPS override (just the datarate is high) but in 5x magnification. Up to now I believed 3x zoom = 5x magnification with fixed live view but apparently it's not like that.

And the FPS timer B still jumps to the original value for me. It just has less influence on FPS if timer A is set to a high value.
