Boeing 787-9 Dreamliner flight images procesing

In this short post, I would like to show you the way how to relatively quickly process the images, taken through the Boeing Dreamliner 787-9 window. Initially, an issue sounds very silly, although knowing the cabin crew policy during your flight you can be really disappointed when you want to take some pictures outside of your window.
How it works? The Boeing 787-9 Dreamliner windows have an electronic system, responsible for the fast switching light control and gradually diminishing effect from clear to dark (Pic. 1, 2). More details about it I have brought in this article.

You have a button underneath your window (Pic. 2), where you can adjust the level between 1 and 5. Level 1 means, that your vista is clear, Level 5 indicates a completely dark window, which is good when flying under solar conditions. Unfortunately, this controller has only a local character, because always someone else can do this adjustment for you. In the case of Norwegian flight, the cabin crew sets the level 3, which is not enough for good pictures. Passengers need at least level 2 for it.

In the result you have got a view like this:

It makes taking good pictures outside very difficult. Basically, you cannot make other colors apart from blue. Images require further processing, which takes quite a long time.
You can do the image processing using obviously Photoshop, Photoshop Lightroom software or even both. Personally, I use OpenSource image manipulation software, which is GIMP and Darktable.
My results can be still out of question at some point, but I haven’t spent much time with it. Anyhow if you experienced a similar situation to me I would like to make you feel a bit better, having a decent opportunity to get your pictures right.

These images have been taken during my journey to the United States from Oslo to Oakland San Francisco. I was flying above Greenland alongside with my group. Seeing, that weather above glacier sheet was pristine I was meant to enjoy the formidable view of this wintry area. I got a blurry blue hint instead!

First examples come from GIMP. GIMP has quite a few color correction and alteration options, that can help you retrieve the natural view of the image.

There is a lot of stuff in the Web, regarding each step, which we should consider when processing our image. I will omit them right now and jump straight to my ready examples below (Pic. 4 – 9):

Similar processing you can do in Darktable, free opensource software, which is a perfect counterpart to Adobe Lightroom. The result looks slightly better, although you must work on it for a longer time.

Finally, you can get pretty nice results, which looks like old photography (Pic. 12). I believe, that you can make a much better result when sacrificing more time for it.

To do it quickly you can always make your image monochrome. That won’t take such a long time, unlike colorized pictures (Pic. 14, 15).

You can always use both programs to make your image as best as possible (Pic. 15).

At the finish, I am showing you the comparison between GIMP manipulation and Darktable image processing (Pic. 18).

In the end, I would like to say, that my image processing was done very quickly. You can do it better for sure. I just wanted to show you the way, how to manage this problem, when you will want to get some pictures of beautiful areas, which you are flying above.
