14bit RAW DNG silent pics! (silent.mo)

[a1ex]

Exactly what I said in this thread earlier...

“[Canon's] image pipeline is probably optimized for fast math, not for high quality."

Now there's the understatement of the year.

When I started working for Apple one of the first things I discovered was all development decisions are made by marketing, not engineering. They don't give a shit about quality.

on my 5dmkii, when I change from raw+large stepped > just large stepped I'm getting 51 frames, as opposed to 36!

Oh man... the bursts are smooth as butter. The pink cast is easy to get rid of,  its very light... I thought it was from digic black level adjusting but still happens... maybe can adjust that down via digic.

[a1ex]

Can you post some DNGs with pink cast?

Most probably it's the black level calibration (maybe it varies with time, not sure).

Here you have Alex

I'd like the raw DNG, not the JPEG.

Can't see any pink cast here (5500K/green=1).

I'm tried this function, then I found interesting thing.
You may push Zoom button and take a silent pic.
We can get 3592x1320 DNG.

On 600D? My zoom is 1/2 height on 6D. I only made it work there so far.. havn't put my UHS card in to see how well the burst bursts.

BTW.. it uprezes real nicely to 2k.

Do you have offsets already, I can copy and paste vs taking more pics, I think I adjusted 1 only.

Pink Cast:

The raw viewers sometimes adjust it out like ufraw and stuff.

In that sample of mine, it makes it to green.  Looks like the correct WB values are not being written to the DNG (along with ISO, shutter, etc etc).

They all load with 6050K/M78 regardless of camera settings.

Here's a shot of a color checker if that makes life easier.

Yeah but when it does work, it's just noise.

On my 5D3 yey!
yes 3592x1320 is 1/2 height. But the picture quality is not so bad , So I think it's a simuler function with 600D's x3 zoom. I mean I guess this is recording pixcel ratio is 1:1 maybe.
I have no idea yet , but I think this is one of hint for clalyfy this function IMHO.

hmm, My DNG has no noise....

I may be color blind, but this doesn't look like pink to me:



Ufraw uses the black level computed by ML. If it's wrong, you can't correct it with white balance.

Exif info is not implemented, just some dummy values.

Yea, the cast is real easy to remove... but shows up in AE and photoshop. Once you do color balance its perfect..

P.S. its real faint. Change WB and see what I mean.

Looked at chdk-dng.c and it is using the old DNG specs 1.3.0.0

It is possible to get LinearRAW jpeg lossy compression in DNG since specs 1.4.0.0 and get a 2:1 to 3:1 compression ratio.

see page.19 http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/products/photoshop/pdfs/dng_spec_1.4.0.0.pdf

You could see some example here : http://blogs.adobe.com/lightroomjournal/2012/10/dng-1-4-specification-notes.html

Oh man.. this would fix it right up... mjpeg anyone?

Little DNG video from 5D3... but there was no sun today, so can not really showoff the latitude.
 - just some random shots

This looks great.

I ordered a 1000x card yesterday to try this stuff out along the way.

Can someone do overexposured video so we can get the right exposure in post? RAW should be overexposued to get more detail in post I will be glad with some samples to

Trees details is bad It is not improvement over stock H.264 video.

This is i guess 720p

Magenta cast due to choosing too high a sensor saturation level in dcraw.

This link suggests leave dcraw to set black level but specify -S saturation point to suit camera performance.

http://www.guillermoluijk.com/tutorial/dcraw/index_en.htm

Also I'm finding just interpreting as rec709 sRGB primaries in linear domain gives more 'accurate' color than some of the default settings in ufraw, darktable etc which appear much warmer.

Could you upload some DNG sample where the girl is?
