Tragic Lantern for 6D

[noisyboy]

Continued testing shows that selecting the 2003 process does go a long way to removing the orange/blue artifacts.

This is a crop in of something I shot a while back

Notice around the railings that there is the orange/blue madness.



Now look at the same image with 2003 selected:



Gone!

The only thing I notice is that it seems to like to stay around anything that is green which is weird but rooftops, brick walls etc it pretty much gets rid of it!

EDIT: Whoops! I mean 2012 not 2013 :p

Interesting so let's start googling what adobe changed btw process 2012 and 2013 !

Yeah! 2003 is the one that seemed to help things

[1%]

Was it 25 or type 25?

type 25 is image 26
img 25 is type 24

[teo770]

The test i made: the best noise & banding test i think

Cap on the lens, 1600 iso, f4 (full open)
In Lightroom +4 clicks on expo.

The best are imgs:
- 25 and 27 exactly the same pictures
- 36 and 38 exactly the same pictures

- 57 and 58 exactly the same pictures. Perhaps an issue here. Pictures even with +10 clicks on expo are full black... as if the pic wasn't take.

I would choose img #25. Banding and color noise is in every pictures but imo, the #25 img shows less banding and color noise.

Others are breaked or show way too much color noise.

Noisyboy, take a pic @ 1600 iso with cap on, then push expo to +4 clicks in LR.
You can compare image switching processus 2012 and 2003....

For me a LOT of color noise added by processus 2003.
It's a lab test... perhaps acting differently with real life pics so... deep test it.

was using EOSM address.. but 24/25 freezing LV

I dunno if there is a difference between AF On/AF off... I took another shot at AF off and didn't see dots but maybe it was not bright enough.

Ok... this might be more "fun" than the images.

Go to debug -> memory browser. Select 7e024.. turn on raw video, then you can try out raw type on the fly.

int32 type 16 is what 5d3 uses, default is hex 22 which is int 34 to keep it consistent.

check out raw zebra on int 23, which is close to the non working img25... also 28 is one up from img27.. they both seem to "clean out" the shadows.

[noisyboy]

Speaking of noise! this looks very cool:

Ps. I will run these tests, just wont get my camera back for another half hour or so :p

[1%]

Thats how I've been finding the dots... but the problem is the silent DNG doesn't seem to match what happens w/ raw video. The img25 type froze LV. I think better to test by just setting it.

[xNiNELiVES]

The 2003 process also removes color shifting. In 2013 process adobe added in automatic settings that you don't even get to control. They apparently automatically add sharpness etc. There, I believe, are ways to remove these changes. Dunno how though. Just google...

[kgv5]

Here you have the raw DNG's for comparing the picture with and without VAF-6D.

Humm, only thing i can change in memory browser is select "5024" for Hexdump

[1%]

Change that address with the arrow keys, right below it is the position you're on.

[teo770]

OK, same test with HEXDump @ 5028

The test i made: noise & banding test

Cap on the lens, 1600 iso, f4 (full open)
In Lightroom +4 clicks on expo.

The best are imgs:
- 18 and 25
- 57 and 58, as you think, histograme is empty, so breaked pic.

It's hard to say again btw img #18 and #25. Noise and banding are there in both... but very close.

[1%]

5028 is the address hexdump goes to by default, its not raw type.

7e024 is raw type, you have to set hexdump to go there, its a memory browser, it'll change right away.

[teo770]

Sorry, definatly out of my understanding...

The HexDump is 6 digits

7e024 is raw type, you have to set hexdump to go there, its a memory browser, it'll change right away.

Where must i set the raw type 7e024 ?
Once i reach the Raw type mem address, what do i have to modify ?

[1%]

Top line, move the scroll wheel.
second line move left to right and then go back up to change the numbers

that is where you're at, then contents is below

default raw type is 22 so

[teo770]

I love comics ! Books with pics !!

Thanks !

As an ideal i shall test from rawtype 20 to 30 ?
And with the "best raw type", in the 100 dngs i would get...

Overall less noise/banding ? Less breaked pics ?

[1%]

You can go from 0-100 (higher, probably won't work), the int32 would be pic number you got in raw - 1

You can change by int or hex... looking for no "hot" pixels/banding and no yellow + purple artifacts around sharp edges. I guess you can take a silent pic or shoot a few frames.

[teo770]

God, lots of combinations !

Just get the best result with rawtype hex32 = 1e
Quasi get rid of banding in every non breaked pic.

What's behind "rawtype" ?

[1%]

Some canon function to chose edge outlining and to apply correction or not.

Tried 1E on some silent pics, no issues.. have look at video + try sharper edges.

[kgv5]

Seems that this is possible to use 6D and EOS app remote shooting with raw. It's getting about 15fps but at least we can see the picture while it is recording which can be very helpful with crane or slider for example without any cables. EOS app has only shutter release, doesn't have LV on/off button. Could we somehow emulate this or just make full shutter release button press to start raw recording (as an option)? (stopping is not so necessary whilst recording in hi res gives only short time recording so it will stop automagically Other thing is when touching the screen we can choose the spot to focus on - so eos app is sending some othe signal to the cam - maybe we could somehow trigger ETTR this way? 

[teo770]

Tested rawtypes 0 to 9 this morning...... very long.

A script firing "Don't click me", changing RawType +1, firing "Don't click me"  ... etc would be nice.
5 scripts to test let's say 0-20, 21-40, 41-60, 61-80, 81-100

20 series x 100 dngs x 4MB = 8GB

Then another script to analyse results.... mesuring noise (counting non black pixels ?)
Moiré, banding... harder to mesure softly...

[1%]

Yea, could have done it a little easier and just changed type on don't click me. Going to give 1E a try and see if the yellow stuff is gone.

Checked 1e in video, has dead pixels marked on the frame.

[noisyboy]

Real sorry I haven't been able to assist with this yet Loaned my camera for the day and still trying to get it back! What are friends for if not to be a complete pain in the ass eh?!
