# [Play Raw] Daylight haze

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

There you go

(I think I’m cheating …)

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)

#24

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!

10?

#26

That is what I also think

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.

#31

Nice sleuthing. I saw 10.

#32

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.

#34

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

(Timur Davletshin) #35

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.

#36

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.

@james

… 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

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

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
