One Photo Focus – November…

One Photo Focus is a challenge hosted by Stacy at Visual Venturing, where we all make edits to the same photo and then we see what we have all come up with on the First Friday of the Month.  You can learn more about this challenge here.

This month’s image was provided by Helen Chen from HHC Blog.

Here is my submission…

wilberGIMP1 Tutorial

The past few weeks I have been playing with Luminosity Masks.  I first learned about them one day when I was reading a tutorial by Pat David.  I’ve created a few of my own tutorials on my take of this technique in my last few posts (Clarity in GIMP, Playing with Luminosity Masks).  I edited this image between those two posts.  Let’s look at my layers to figure out how I did it…layerstutorial

*** I used some of the same screenshots from previous posts because I did the same thing, and it saved me some time while creating this tutorial. ***

  1. First, I brought up the RAW image in DarkTable3.  I made a few minor edits with exposure, contrast & brightness, I picked a black point in levels, and it looks like DarkTable is set to have a preset base curve determined by camera type.  **I’m new to DarkTable and am still figuring it out.**Helen Chen November One Photo Focus--DT_LR1000
  2. Next, I played with Luminosity Masks and the Local Normalization filter (which I go into detail about in this post (step 3)).  Like I did with those previous two posts, I created 9 Luminosity channels by running the script mentioned in Pat David’s post [Filters->Generic->Luminosity Masks (saulgoode)] on the base image layer.

    channelsThen I ran the G’MIC2 plug-in filter Local Normalization [Filters->G’MIC->Details->Local Normalization] making sure to set my input/output to these parameters…gmic-input_outputI used the default settings (ignore the preview – this is the same screenshot from a previous post)…local-norm-gmicThen I made a duplicate of the Local Normalization layer 9 times and added a different channel mask [Layer->Mask->Add Layer Mask; selecting Channel] to each one…mask I ended up liking a combination of three of the layers with masks (channel L at 50% opacity, channel M at 50% opacity, and channel DDD at 100% opacity).

    Once I decided which layers with masks I wanted, I made a new layer from visible [Layer->New from Visible].

  3. I tried several ideas to make the white bits between the tree leaves blue, but ultimately I didn’t like an of the things I did.  Instead, I created a duplicate of the visible layer created in step 2, then I went to Hue-Saturation and played with color saturation [Colors->Hue-Saturation].  I wanted to amp up the red, and I altered the yellow and green too…green-yellow-red hue-sat-rgy
  4. For some reason, I decided to just remove the blue (and cyan) and I ended up liking the result.  I made a duplicate of the hue-sat layer created in the last step [Layer->Duplicate Layer OR Shift+Ctrl+D OR duplicate-layer], then I went to Hue-Saturation again [Colors->Hue-Saturation] and removed the blue and the cyan completely…blue-cyan hue-sat-bc
  5. Lastly, I created a curves layer and applied a mid-tone Luminosity Mask to it.  I made a duplicate of the hue-saturation layer created in the last step [Layer->Duplicate Layer OR Shift+Ctrl+D OR duplicate-layer], applied a Luminosity Mask [Layer->Mask->Add Layer Mask; selecting Channel M], then pushed the whites and the blacks in curves [Colors->Curves]…curves-redCreating my final image…Nic_Anderson-November-One Photo FocusAt some point I played around with cropping the image, I thought I had decided not to crop, but it looks like I did take a bit off each of the sides.

Kind thoughts and comments are welcome!

  1. I, too, love the colors you have added to the photo, and because of that, I think, you also add some depth to it. I like your photo a lot, but your tutorial is not for a beginner like me… yes?
    Thank you so much!

    • Thanks, Helen! 😀 Some of my tutorials are more intermediate, some are more basic. This one does assume that you’ve been checking out a few of my tutorials prior to this one. One of these days I’ll organize my tutorials by level of skill, but I usually link back to the tutorial where I talked about a concept that I don’t want to explain again. 🙂

  2. Wow, I can’t even begin to comprehend what it is you did (despite your wonderfully written explanations), but I really do like your final edit 🙂 I love the realism and the lush green of the foliage just makes me feel as if I’m in a jungle!
