Set your base ISO for highlights (Zebras/Histogram/AutoETTR), and enable the needed recovery (Histogram/Zebras).

Cheers.  I notice 3 colours in the zebras: white, green, and red.  Red is obv overexposed, white is under ... what does green signify?  Back on topic after I promise!

#a1exforpres

you started the video with a very underexposed image

What's the best method to ensure both ISOs are picking up the maximum signal without clipping?  Histogram I guess?  I was using the spot meter (%) but I am thinking that may not be good enough.

One more ... this time comparing 100 to 6400 and then combined.  This was purposefully a very taxing image to capture with two light sources, diagonal lines, and very dark and very light parts of the image.



It can't be stressed enough that this development is groundbreaking and frankly I think a1ex for prez!

@a1ex, with auto shadow recovery enabled in photo LV, ML menus become laggy.

Audionut I just downloaded the builds you posted and I can't find the auto shadow recovery under the Dual ISO menu.  Any idea?

I am just BLOWN AWAY by the extra Dynamic Range for still photography.  Wow!

It is looking WAY BETTER a1ex!  I am really impressed with the quality... however the vertical line problem is back.  I've edited the picture below for clarity and if you look closely at the video in 1080p you'll see the lines in the upper-right corner.  Image full-size is here: http://postimg.org/image/j93dgsinh/

Small converter update:

- fix crashes in cr2hdr with some unusual pics
- fix red "zebras"
- nicer highlight handling (aliasing artifacts should be blurred)
- minor tweaks

Is the EXE posted in the OP kept up to date?

Another with crawl. Switch to 1080p and look at the bottom of the fence towards the end:

Hahaha, that's my video ... and my wife ... and my backyard! #winning

Got it to work. Had to move the whole package to the virtual box desktop. rather than using the virtual drive.
Thanks for your patience. THis is gonna be fun

Nice one.. I'm just getting my VM environment up and running again after failing with WINE and WINEBottler to get the EXE to run.  Post some samples when you get em!

Hi audionut. Thanks for helping. cr2dng app? Do you mean cr2hdr? Can,t find any cr2dng

Yes that's what he meant, available in the original post.

@dubzeebass: that was a bug solved a while ago, turn on sync beep if you still use an old version.

I use the latest build for 5Dmk3 from Lourenco, will turn on Beep and see if that sorts it out.

Now I think the algorithm is suitable for some really nice shots (photos+videos), not just aliased keyboards in black caves

The new one looks way better.  Still that chroma aliasing ... I wonder is it possible to pull the colour from surrounding pixels on anything that's got a jaggie and has an RGB level near clip while other levels are relatively low for that area?  Might not work if something is supposed to be jaggie ... but could help with the chroma aliasing.

@dubzeebass: can you upload a sample? (less than 1 second of video, if possible).

Did it work better with a previous version?

a1ex, it appears to be just the frames at the beginning of the video that do that interlaced pink highlight thing.  It's akin to the judder that some people get, myself included, when viewing a rendered RAW file - the first few frames repeat back and forth and then it continues normally.

Another video ... I used the Shadow 050 one again and I think it gives the best results.

Is there any way to implement this in such a way that each sensor records individually to the CF card?  Obviously it'd be double the data rate (ergo half the write speed per channel on the CF bus) but it could be a start?

I'm finding it difficult to properly set exposure, though I'm sure this will improve as code revisions progress.  This RAW converted with the Shadow 50 executable is particularly special.

I just did a test using fine details (fur and grass) to demonstrate the line-skipping.  This is of course a "worst-case" video, but it should help to show the interlacing.

Question for lourenco mainly ... when I look at my Modules based on the June 27th build, the CF ACC one has OldAPI listed.  Is this an issue?  It seems to work OK but I just want to make sure it's all optimized.

why you don't just put your ML in the CF card ?

Most of the "This is how to do it" step-by-steps involve putting ML on the SD.  Six of one, half a dozen of another I guess!

If you Search for Hack3D you will find this thread:

You got it.  Be Warned

The menu specifically says HaCKeD mode which I asked about, but apparently I'm supposed to know it's Hack3D?

Hi folks,

Is anyone experiencing freezing when the HaCKeD mode is on?  The buttons still work but Liveview shows a frozen image, even with GD off.  Is this on purpose?

Before the lovely thread Nazis jump down my throat about SEARCH TEH THREAD1!!!!!! ... I recommend searching a thread about a hacked camera for the word hacked yourself

Congrats!  Donated.
