@gadolf (Gustavo Adolfo) posted a new topic, subject "[Play Raw] Watermelon". It read:

   I tried to bring out a bit of detail from the shadows and to that I relied mainly on filmic.
    
    As usual, extreme noise from a very old and cheap camera. (Please, be patient…)

    @anon41087856 I must say that the new filmic presets (still on dev) are more than welcome and save a lot of time tweaking the filmic settings. I've done a couple of edits in different images and most of the time they nail it. Thanks for the effort in trying to improve this tool.  
    In this photo, I used 16EV:

    Hmm, where is the link to the raw (dng)?

    Fixed, thanks!

    **Edit** did more adjustment

To which @shreedhar (Shreedhar Inamdar) replied

    A crop that focuses more on the watermelon.

    Morning, @gadolf
    
    Tricky task!  
    It is very easy to bring out much more from the shadows.  
    But those blown watermelon highlights are more problematic.
    
    Hm, I wonder what'll happen if I … … …
    
    I'll be back!
    
    Have fun,

    Oh , my watermelon was overexposed. Did some adjustment…

    > Oh , my watermelon was overexposed. Did some adjustment…
    
    Just in case you don't know how to do that, I would do the following:
    
    1 - Uncheck Clip out-of-gamut colors box  
    2 - Check Highlight reconstruction box  
    3 - Move the Highlight compression slider to your taste.
    
    I'm a Darktable user, but when it comes to highlights recovery, I get better results with Rawtherapee: after recovering in RT, I just export a 32-bit REC 2020 tif, then I do all the rest on DT.
    
    You've got some pretty nasty artifacts on that region, but the overall edit that you did is pretty close to what the scene was, in terms of lighting and colors.
    
    My edit was purposely dark to represent my vision of that scene: the watermelon and specially the light reflection beneath pop up in front of me.

    There is something wrong with your highlight reconstruction.

@DxO-user (JegMeg) replied

    @DxO-user Could you please upload the pp3 file of this last edit?

    Strange… I opened the raw file and applied your last pp3 and got this:
    
    image986×491 450 KB
    
    Still blown out but not bad, and totally different from your jpg.
    
    And if I check Highlight reconstruction I get this:

@gadolf (Gustavo Adolfo) replied

    @DxO-user also open my pp3 (below), go to the Advanced Tab and look for the Wavelets section.  
    There you have much more control on noise reduction.  
    My settings in there are just an example of a very quick tweak to reduce noise, but FAR from good, just a starting point. I couldn't reduce almost any luminance noise, but, at least, some chrominance noise has gone.

    gadolf:
    
    > Are you editing the raw file (.DNG)?
    
    Yes , I'm editing the RAW file - But I have to use local adjustment to get control over the blown out highlights in the melon.  
    As a newbie to RT , I have to use to this kind of adjustment.
    
    If not using RAW , I have to save as a tiff and do the rest in Affinity ( have never used Affinity in this forum)

So @Carmelo_DrRaw (Carmelo Dr Raw) replied

    @gadolf  
    My first take with PhotoFlow.  
    I have been testing some experimental tone mapping code on your image, and this is the best I could achieve so far… I will add the photoflow .pfi file once the new code is committed on github.
    
    CRW_4166-phf11606×1200 514 KB
    
    P.S: I made no attempt to reduce the noise for the moment…

@gadolf (Gustavo Adolfo) replied

    @Carmelo_DrRaw Looks promising.
    
    Glad to see that my watermelon can be useful to your development process

    Sorry, what is this screen about?
    
    I really don't know Rawtherapee…

Then @DxO-user (JegMeg) said

    I have made 3 control spots ( appears as an elipse )  
    Inside each elipse there is a small round circle. Hit this small circle and you can move the control spots up/down - right/left to your likings.  
    In this case I used thwe control spots to adjust the exposure …
    
    Don't mind the straight line.

To which @Claes replied

    And what would the result be?

    Local adjustment comes in handy. Once you get used to it - you can't live without it

After which, @chroma_ghost added

    @gadolf, fellow users, watermademoiselles {cap's off}
    
    Best result I managed was rawpeeparis' sacrificing natural looking (contrast) highlights to a Log munch scream puddle in exchange. Where is? I could swear I've been there.

    > Log munch scream puddle
    
    This was hard to decipher  and it fits perfectly!
    
    I also didn't like the resulting geometric shape after highlights recovery, so I choose to find a half term and reduced a little the recovery effects. (now looking at my edit I realize I should have reduced it more, the shape is still there)
    
    As for the location, well, it's the Glória neighbourhood, a small and very crazy and exotic place in RIo (but you have to live here to fully realize how strange it is, it's not so evident at first sight). On Sundays, cars and buses give place to this market. So this is Feira da Glória (Glória's market).

Then @Joan_Rake1 (dumb) said

    Butterworth bandpass, unusual curves, warping and odd layer blending.

    Hi.  
    Is it my impression or are you going less abstract in 2019?

To which @Joan_Rake1 (dumb) replied

    Definitely not!

So @afre (Alan) replied

    Nothing like watermelon on a hot day… but it is cold where I live. Lately, I have been burnt out, so my processing has been a struggle. Lots of steps this time! Did some dodging of the watermelon in GIMP, which I rarely do. _My dodging skills are non-existent._
    
    **1.** `PhotoFlow` → HL mode (blend) → AMaZE → linear Rec2020 (no clipping) → tone mapping → reduce oog (curve 0→1) → linear sRGB 32f (one with tone mapping [ **A** ], the other without [ **B** ])  
    **2.** `gmic` → crop (1.5:1 **A B** ) → filter pixels ( **A B** )  
    **3.** `enfuse` → merge (contrast **A B** ; probably should have chosen exposure)  
    **4.** `gmic` → remove alpha → filter pixels → filter noise (hot pixels, guided)  
    **5.** `pnmclahe` → enhance contrast  
    **6.** `gmic` → boost shadows (curve) → adjust brightness, contrast (curves)  
    **7.** `GIMP` → dodge (select dark areas of watermelon, blend)  
    **8.** `gmic` → increase chroma (curve) → sharpen (LoG) → resize
    
    Zoom 100% and enjoy!
