Post DeSERt - New Deflicker Software [soon to be released]
Hello everybody!

My name is Johannes, I´m from Austria, got very interested in timelapse photography and:
since the last few month I´m working on a deflicker software which works in combination with RawTherapee.
It is called DeSERt for Deflicker Software with Exiftool and Rawtherapee.

I get pretty decent results already but I need other people to test it in different situations.
If you are interested in testing, contact me please (PN or at bildstein.johannes[at]gmail.com)
I´ll send you the latest version and you send me back information about bugs, problems, suggestions etc.

Most likely DeSERt will be available for free once it is stable but for now I don´t want to publish a alpha version for everyone.

What you need:
#Windows XP SP3 or newer with .Net framework 4 http://www.microsoft.com/download/en/de ... x?id=17851
#RawTherapee (free) http://rawtherapee.com/downloads
#Hardware: if you can run Rawtherapee, running DeSERt won´t be a problem

It features:
#Fully automatic flicker correction
#Custom Brightness outcome curve
#Custom WB, Tint, Black, Brightness/Contrast/Saturation curves

Limitations:
#Windows only (I want to make cross platform support later)
#no camera movement (will come as a future feature)
#it´s still in alpha status -> need testers to make it better and stable

So, here is a screenshot of DeSERt in action:
Image

And of course example videos:
This one was made with a DSLR in full manual mode where I manually changed the exposure time a few times as it was getting darker.
You can see the change of the brightness in the screenshot above.
The left side simply was batch edited with Rawtherapee with a single Postprocessing profile.
The right side was edited with DeSERt with a custom brightness outcome, WB and black curve.


This one was made with with a DSLR too but this time I simply used Aperture priority.
Same as before, left is simple batch processing and right side is edited with DeSERt.
(the little bit of flicker you can see in the edges is caused by vignetting, I´m working on that though)


I hope I could awake some interest, if I forgot to mention something or you simply want to know something else, feel free to ask :)

awesome, the results look damn good!

From the screenshot it looks to take native RAW files? If so, what does it output as?

Ill drop you a pm and get testing :ugeek:

Hi agour,

thank you, happy to hear that :)

Yes input were Raw files, it´s also possible to use various other formats too.
Output was in this case jpg(100%), it´s also possible to use png and tif as output (only 8 bit atm but with a little workaround also 16 bit (it´s problem with Rawtherapees command line options))

Very nice with a free software that does not require additional software such as Lightroom etc.

If you want to release this to the public you could probably use the same approach as the guy who did "Universe Sandbox", that you could try it for a couple of days, but had to donate in order to get the software. But you could select yourself what you thought it was worth, as low as one cent. I don't think anyone doing serious work would not donate more than a few $ at least (compared to what Lightroom costs).

@Matjoez, I´m working on the cross platform issue :)

@ev1te, thanks for the input, working with donations would be a great way.
I´m also thinking about maybe making it Open Source (only after it´s stable though) but this doesn´t exclude asking for donations :)

the results are amazingly good!

would love to test it out...
pm sent!

and i think donation ware is great... since most people working in that business are willing to pay for the things they are using and that are worth it.. :-)

I also am on a Mac and would love to try this. I'll keep watching this thread to see when it's there. And I would definitely donate. Those results look great so far!

Post Re: New Deflicker Software [searching for testers]
Hi again!

Quite some time has passed since my initial post...

I wasn´t lazy all the time but worked hard to make DeSERt better.
What I did was
#fixing various bugs with the help of all the testers
#adding some smaller features for better handling
#added multithreading support
#trying to make DeSERt cross-platform with success (nearly at least ^^) on Linux
->DeSERt runs on Linux (Ubuntu) but the UI looks a bit strange and some smaller things don´t work properly yet
->I couldn´t test it on Mac as I don´t have one available but it should work too (anyone wants to try? (you´ll run into bugs quite surely though))
#working on a calculation algorithm for a moving camera (still quite some work to do but it´s going into the right direction)

On a sidenote: I´m also thinking about adding Lightroom support. I haven´t been working on that yet though.

Well, so far about the updates...
Thank you to all the testers and I hope I can soon give another update with all the big features running :)

Have a nice day
Johannes

Post Re: New Deflicker Software [searching for testers]
Hi Billy,

I'm interesting to understand which algorithm/techniques you used for your software to achieve such results, I'm trying to implement a deflicker script and would appreciate some tips ;)

Right now mine look like this (simplified):
- scan all picture to determine their "luminance" (formula = math.sqrt(0.241*(r**2) + 0.691*(g**2) + 0.068*(b**2)) where r g b are mean value over scanned picture)
- based upon luminance values, create a moving average (http://en.wikipedia.org/wiki/Moving_average) using a window of 10 pictures.
- for each picture find the best brightness-contrast combination to get a luminance as close as possible to the moving average

On a sample set of pictures it gives me the following result:
Image
- Blue: luminance calculated from initial shots
- Orange: moving average (best value to achieve)
- Yellow: value actually achieved

Calculate mean luminance of a picture is not really difficult, the most difficult part appears to be changing luminance.
Which technique did you used ?

I used ImageMagick and brightness-contrast feature but I'm sure there is a better way to do this
Basically this feature takes a parameter between -100 and 100 (with 0 = no changes) so the script makes multiple tries to identify the best parameter to get a luminance as close as possible to the moving average (orange line above).
To make the script faster (and not test 100 combinations each time) I built the script in a recursive way, starting from 0, it moves 10 by 10 until it finds the proper interval, then it moves 5 by 5, then 2 by 2, then 1 by 1.

The script takes 3s to process each picture (1920x1080 pictures)

But working this way do not allow me to get the exact moving average, I can only try to be as close as possible. And this technique takes some time, processing for 468 frames is +/- 16 minutes.

I still need to figure out if (how) I can "smoothen" values, increasing window size (number of pictures to take in consideration to calculate ideal luminance value for a picture) do not help much.

Right now I don't find this script to give very good results, maybe I should work out another "way" or try with other shots.

Any input would be really appreciated ;)

@numax and timeless
Thank you for your interest :)
I haven´t had the possibility to test DeSERt on Mac yet but I have changed quite a lot already to make it ready to run on Linux and Mac.

At the moment I´m quite busy making a new version ready to test. Quite a lot things have changed and DeSERt is getting better and better.
The GUI is completely reworked and also the code got restructured to make it easier to add new features and handle bugs better.
The brightness calculation algorithm got a lot faster and it should be possible to correct timelapse with camera movement too (have to test how good yet)
It is now possible to change all numerical values from Rawtherapee over time.
plus a few other smaller changes that simply makes it easier to handle everything.

soon finished will be an option to correct (ND-)filter changes with few effort.
All you have to do is making a photo for each filter-combination and load it into DeSERt to create a filterset.
Then you can use this filterset on all your following timelapse you have made with this lens-filter combination.

what I also will do soon is a possibility to animate the crop of the image. (which should be done rather fast)

Once I have this current version running I´ll go on and start with Lightroom support!
Before I´ll start with Lightroom support I´d also like to release DeSERt publicly so that all of you waiting can finally try it too.

A few new videos will also come soon and I plan to make a little intro-video for DeSERt.

Kind regards
Johannes

Hey everyone!

I will give out a new version to all tester today and if I don´t get any major bugs there DeSERt will be publicly released as open source software!
So stay tuned, it will be available soon!

I´ll write a new post here and I will edit the initial post when everything is ready

Kind Regards
Johannes

I'm definitely interested in testing as well. I live with a view facing the Seattle skyline at sunset and often record timelapses of the sun and sky — in fact, I took an HDR timelapse of the sunset and clouds last night that I have yet to process.

I'll get on that PM.

This is a deflickering test I did some time ago with v1.0.5 alpha



It was shot in Av mode, it did an amazing job removing the flickering.

Please ignore the shakiness :P

Hi Johannes,

This is going to be of high interest for Nikon users I imagine. Canon users are nicely catered for for sunset and sunrise bramping but Nikonians not. Shooting in Aperture priority mode with no lens twist would extend the time span of the Nikons at those times. What`s the latest?

Hey guys!

Sorry for not updating for so long...
I don´t get to develop as much as I´d like to. But still, DeSERt is growing.
I´m still fiddling around the XMP/Lightroom support and also on a few structure changes for better file handling.

About Mac support, thanks to a wonderful tester, I could fix a few things but I can´t say it´s running smoothly yet.
it´s a bit difficult to develop for a platform if you don´t have it available, so it will take longer till mac is really supported.

Thanks for your patience,
Johannes

Hi,

DeSERt looks very promising. If there's still needs for the testers, I can help. And I'm using Linux.

Hey everyone!

DeSERt doesn´t run on Linux smoothly yet. (probably some problems with filepaths and/or program calls)
if you are still interested to test and maybe want to debug it, you´re welcome to contact me for further information!

@absancakli: Thanks again, it´s very interesting :)

Hello!

No more news about the software? I searched for but not found anything.

Thanks!

Hi,

there is no news about DeSERt but I'm activly developing a new piece of software that is more flexible than DeSERt.
It will be called LapseStudio and wil be (or actually, is already) compatible with Adobe CameraRaw, RawTherapee and has an internal processing.
The program is developed quite far already and I'm currently working on a better brightness-algorithm and on a few last details (that usually take the most time).
I know it took quite a while already but I want to make sure to have a well designed piece of software for easy bugfixing and easy further development.

So, don't worry, I'm still on it and will let you know when I have something ready! :)
If anyone wants to know more, feel free to ask

Kind Regards
Johannes

hi i have really no background in timelapse and now planning to start with this application. so by now i am trying to look all the best possible accessories and softwares to help me with my learning process. i have found this forum and look on the video review and i can say it was an impressive software to help the deflicker problem. i have manage to install the RawTherapee but not the able to run the DeSert on Window8 system. I also look on your Timescapes but again no luck. I really appreciate if you could help me out how to install your software, thanks
