       | Looks nice! I noticed that at the bottom of the page there is an
       | e-mail sign up box that says: "Don't See Your Favorite Place?
       | Know when we release new maps." Now I know e-mail sign up forms
       | usually come canned in a bit of javascript, but it sure seems
       | like it would help if people signing up could also include a
       | place they would like to see. I'm not in the market for this kind
       | of thing but I was hoping they would have the San Francisco Bay
       | Area on there. Santa Cruz and the Monterey Bay would be cool too.
       | Definitely want the bathymetry on those ones. I thought the
       | bathymetry was a nice touch.

       | I had an idea to sort of automate this process or even a user
       | aided wizard as a product but never to round to the mvp. Still an
       | ok idea I think as satellite imagery on wall is great talking
       | point. It can be beautiful, dramatic, always changing so makes
       | for sets of images showing changes etc

       | picture and the final result on the top).
       | 
       | Unfortunately the explanation for that step is only a few
       | sentences..

         | Bump the contrast and saturation and you'll be pretty close I
         | reckon.

           | As someone who don't know how to use Photoshop, it's
           | interesting to learn (as you said) that, most the difference
           | is only contrast and saturation.
           | 
           | The final image just looked so much better than the second
           | last one for me.

             | Photoshop gives you a lot of tools to tweak beyond simple
             | contrast and saturation sliders. The curves UI has been in
             | it in some form since very early versions in the 90s. It
             | lets you dial in a transfer function for each color channel
             | (or luminance) as a bezier curve. The UI shows you a
             | histogram so you can easily understand what's going on with
             | the actual numerical values, avoid clipping, etc. There's
             | plenty of smart tools in the more recent versions too.
             | 
             | Another simple but subtle advantage is you can do these
             | corrections in a perceptual or near perceptual color space
             | like CIELAB, rather than simple RGB. Particularly when
             | you're pushing saturation this gives more natural looking
             | outcomes.

       | Blending the colors in Photoshop manually seems very tedious.
       | 
       | The open source Enblend/Enfuse, which ships as part of the open
       | source panorama stitching software Hugin, does it automatically
       | and seamlessly.

       | These look great. I love the insights on the tuning process and
       | it's nice to know it isn't just a lazy cropping.
