If you put a strobe light in your toilet you'll actually see an animation of your internals while taking a piss.

I know that this sounds crazy, but is 8bit RAW possible? Sorry if I sound like a noob.

The best feature of shooting RAW on my 5D2 is the aspect ratio control. I can use a lot more of the sensor than shooting in H.264 allows me to. Shooting in 3:2 and 4:3 allows me more creative control in shooting for instagram/facebook because of the larger vertical resolution these sites are intended for. It also helps when shooting anamorphic because of the 1.33x horizontal squeeze!

If 8-bit raw sounds too weird, then is there a possible way to control aspect ratio when recording in H.264?

You won't get any benefit from it, the size is pretty much the same as 10 and 12 bit.
Plus I would assume it would result in banding.

You should probably update your ML firmware.

Tutorials and Creative Uses / Re: Reflections on ML & CHDK
« on: March 01, 2019, 04:41:34 AM »
The first digital camera I actually bought (and I was quite late to the party of digital cameras in terms of owning one myself), was a canon and I made sure it was one that CHDK could run on.
It was in beta for this camera but worked perfectly fine at the time, back many versions ago. However when I tried raw it revealed how terrible the sensor in the camera was by showing the colours it actually captures compared to what it should be made available through the picture style.

I did find it worked with my brothers EOSM mp4s,
but as far as the movs from my 550D, turns out it doesnt like the audio,
so it will only cut and export if i select it to export with no audio.

Unfortunately it doesn't seem to do my MOV clips from my 550D, they play in it though.
I think the playing is done through chromium, then the muxing is done in ffmpeg.
I'll have to play with it a bit to see if I can get it to work, plus i have to try it on some other clips as well.

Post-processing Workflow / "LosslessCut" Video Trimmer
« on: February 23, 2019, 02:36:59 PM »
Just came across this! Been wanting something like this for a long time.
(I have not yet tried it myself)

https://github.com/mifi/lossless-cut
"Save space by quickly and losslessly trimming video and audio files"

This is not an advertisement, I just found it and thought I definitely need to share.
It runs off ffmpeg, and I was actually unaware ffmpeg had such a cutting capability.

Anyway, hopefully this means no more re-encoding a lot of videos for me.

96 isn't possible on any camera https://docs.google.com/spreadsheets/d/16cgnRivbUv7nA9PUlCLmLdir3gXdIN3pqzCNAAybepc/edit#gid=5
in digic IV. Unless anybody's tried overclocking the SD card speed.
Probably wonldn't need to if RAW compressed (or lossless whatever stupid name people were calling it) could work.

Raw Video / Re: Before I give up on ML raw video ...
« on: January 05, 2019, 03:23:28 AM »
I think everybody has misunderstood what you're saying.

For one, you didn't link a comparison video, the two videos you linked are the same.

And the problem isn't youtubes compression, it's your export compression and/or your compression from raw to whatever you are converting to.

I'm going to bump this in case there's somebody new who can scroll through and look at the pics and make a good suggestion.
Wow 120 days this lens has being sitting dismantled on my table. It's gotten quite dirty lol.

Thanks Garry.

Is this in terms of the cameras inbuilt luminance curve do you know?
The fact that cameras LUTs or whatever the terrible S curve is referred to isn't linear (or a constant logarithmic curve).

How long has that dongle existed? I've had sketches of a similar idea since I bought my 550D :P though that was quite a few years ago and my sketches were of a much bulkier attachment :P

I'd like to see being able to link 2 cameras together and have them sync for stereo photography and video.
There was a spinoff of CHDK that did it with point and shoots.
The part of having them sync settings I'm sure wouldn't be hard with an in between device,
it'd be the syncing of the photo being captured that'd probably be difficult.

Haven't been on the ML forums for a little while, but I'm not sure why there's no other responses.

This looks pretty cool!! And I will try it out in the next couple of days.

Taking a look at your blog also.

    What's the status of your lens? Any luck? I hope it's possible to fix on your own.

Was just about to put an update here that I am out of ideas for getting that ring out, I can't get a good grip on it.
I even made my own silicon ring to the right size and couldn't get it.

I'm not sure if that outside ring can turn or not or if it's screwed in place.
I'm theorizing that the inside ring got tightened, then the outside one which basically acted like a second nut, locking them both or at least the inside ring in place.
That's if the outside ring can be unscrewed off without undoing screws under that cover ring with the writing on it.

Still not sure how to get either of them off.

Sorry to bother. Please clarify: is 0.7m a number which you read on the scale, or you have measured actual distance with you film camera (or the proper DSLR adapter)? Or just both?
If you are absolutely sure, then yes – rubber gloves and the smallest drop of liquid silicone grease (but be careful with the lens) will make the trick… But I’m not so sure)

0.7m is the number on the scale, I haven't measured specifically with the camera but it is certainly close to that.

“this one twists out” – it locks the front lens. Leave it as it was. Try to avoid sliding and rotating the front lens. Some people use fridge or smartphone vibration to settle the lens down, then tighten collar. Don’t use any force. If you get terrible lack of sharpness – it means the front element is a bit off.
The branded collar and the filter thread should be one piece, I can’t believe you ever rotated them separately (I can be absolutely wrong, naturally). But this part does nothing about focusing.
“bottom of this collides with the top of this” – yes, at this position the lens is focused to the infinity or even behind it.
So now you have 6 (or something alike) variants to screw these parts together. Screw it in to the end, screw a bit back as you need to set the synching thumb to its place (on the photo). Then check the focus with the camera (don’t rotate the ring while mounting, just check whether it’s infinity or not). When you find the lucky position and focusing works from end to the end – it’s time to look at the distance scale.
Does it show the wrong numbers? If so, find some small screws in it, release them. Rotate the scale to the correct position and fix it. If so, you are done.

So the bottom that collides with the top does not happen at infinity is the problem. It happens at 0.7m, I have to screw it off somehow, unsure how, maybe it's locked on with screws behind the trim ring.
I can untwist that middle ring and remove the first element at the front, it is not attached to the trim ring.
I won't need to customize the focus because there's a separate ring that defines the start and end point. However I can't reach the end point (the infinity point) because of that collision.

Getting traction on lens elements and retaining rings can be a pain. I have used rubber sewing thimbles or even rubber coated gloves with moderate downward pressure. This should give you enough grip to unscrew the ring unless it is glued.

I don't think it's glued because i feel like I twisted it on at one point just with my fingers when it was loose.
However I have tried a latex mat and also a rubber oring, but I think the thimbles sound like a better idea.

Have you disassembled it in two parts? Looks like it.
What you have inside of the screw helicoid now is multiple thread i.e. there is more then one way to screw the lens part in. So just draw some marks and check all the possible combinations. But there may be a kind of thumb (like that http://album.foto.ru/photo/2921784/ - possibly skewed) and parts of aperture control, which prevent the lens block from screwing in to the end. It's just a guess, I've never saw your lens.

I should get some pictures up. I did fix the problem I made, it's not  back to its original state of only getting to 0.7m. I have pulled those things picture out which is what syncs the screw focus to the end point ring that just twists back and forth. The thing that just twitst back and forth is fine.
I the the problem is, somehow, the top of the lens is screwed too far on, so that ring stops it from twisting further because it collides with the base below it.
The problem I'm having now is I both cant get it off, or the ring inside it which has all the lens specs on it. When I try to undo that the front lens element unscrews instead.

Does it have a adapter with correction lenses? FD mount, IIRC, needs a correction element between the sensor and the lens, to make it focus in the infinity.

I don't mean the focus in the camera, I mean the actual physical focus on the lens, it won't twist to the infinity state.

I've managed to do something because before it was only getting to 0.7, now it's only getting to 0.3, so I've made it worse...

The focusing is basically a giant screw, disconnecting the lens the twisty part can still click from end to end, macro to infinity, but the lens part won't physically screw all the way to infinity.

    You could try visiting a local camera shop, and see if there is someone knowledgeable in vintage lenses. You can see if they know of a repair shop for vintage lenses. You might be able to send your lens for repair at Duclos. Here is a link: https://www.ducloslenses.com/pages/services

The price of fixing a lens is usually more than a new lens :P
There's not much for option in terms of camera shops where I am in Australia.
I'll check out the youtuber.

I have a 24mm Soligor 2.8 FD mount. Everything works on it but I can't turn the focus to infinity, it jams at 0.7m, but can be turned the other way all the way to 1:4 macro.
I can't seem to figure out what is stopping it from turning any further, does anybody have any ideas or advice?
