[Play Raw] Daylight haze


(Timur Davletshin) #21



I do not want to be problematic (just a little), but could we have them de-hazed?

I may be wrong - but I do not see 11 windmills. But of course, your monitor could be better than mine :frowning:

Have fun!

There you go


(I think I’m cheating :roll_eyes:…)

DISCLAIMER: I took a printscreen from darktable zoomed at that area (very bright), pasted it on Gimp, exported to tif, opened it on DT, and applied filmic (auto tune, then tweaked black relative exposure)


Good evening, @gadolf,

No, I do not think that you cheated – more or less any method would be OK in order to reach the correct answer.

BUT: You forget to answer the question!!! How many windmills are there?

Have fun!

:slight_smile: That is what I also think :slight_smile:

But the 11th, which Tamur found, might,
perhaps, be there as well (number 3 from
left in his foggy image).

Have fun!

Sidenote: Nothing against gimp, on the contrary, but I didn’t need to take a so complicated tour. I could have used the very easy duplicate manager from DT to make a copy, then crop it and apply the same filmic I did before… anyway…


RawTherapee (shamefully not upgraded to latest - so no dehaze tool for me!)
Mainly the graduated filter and a very custom tone curve, plus a bit of tone mapping to add back some local contrast.

and to satisfy @Claes same as above but no resize and at 100%


Ten. I believe these ten windmills are near the Miradouro do Pico da Vara atop Sao Miguel in the Azores of Portugal.

Here’s a clearer view:

The shot could have been taken {18}{1\over4}\ \mathsf {km} away at one of the lookouts near Santa Iria:

An images.google.com search using my jpg with the descriptors sea coastal cliffs fjord led me to this wallpaper of a similar shot. The author had used the keyword Azores; modifying the search took me to Sao Miguel Island, so off to earth.google.com I went.


Nice sleuthing. I saw 10. :slight_smile:


Looking at the historical data in Google Earth Pro, it looks like the windmills were built sometime between 2009 and 2013.

@HIRAM, this picture was geotagged manually, so location is not very precise.


Reading the gps tag online… http://exif.regex.info/exif.cgi?url=https%3A%2F%2Fpixls-discuss.s3.dualstack.us-east-1.amazonaws.com%2Foriginal%2F3X%2Fe%2F2%2Fe23f9ee5d9673110bf08f54726b853b4e7bf493a.jpeg

Looks to be tagged a couple of towns away in Ribiera Grande.

Fixed it… in my collection ))) BTW, it would be great to show GPS heading information in maps mode. Those pictures tagged with GPS device have this information.


@timur Thanks for uploading this image!

It gave me (as well as many other forumers) great joy! Also, it made me test other modules in order to conquer the haze, which means that I had a chance to learn something new.


… and to satisfy Claes…

Thank you. After all, the topic of the thread was to kill haze, wasn’t it? Not to hide the windmills :slight_smile:

Have fun!

With Rawtherapee 5.5 - branch newlocallab, with 2 process

  1. dehaze on all image
  2. Retinex on top of image with local adjustement
    Of course I could refine the work, enlighten the image, play on the contrast, but I wanted to do what we can do by adding “local” to the global

I tried to give the hazy top some extra definition. Some haze is nice :slight_smile:

EDIT: Here is the sidecar (darktable 2.6):_DSC0653.NEF.xmp (18.3 KB)

Same image as the first, but with local adjustement at th bottom , increase exposure
