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. | rado wrote: | They have it: https://ramblemaps.com/san-francisco-bay-area-map | TaylorAlexander wrote: | Oh cool! I guess I scrolled too fast or something. Thanks. | [deleted] | benboughton1 wrote: | 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 | sillycross wrote: | It seems like the last "Improving the color" step is what gives | most of the atheistic effects (by comparing the second last | picture and the final result on the top). | | Unfortunately the explanation for that step is only a few | sentences.. | pope_meat wrote: | Bump the contrast and saturation and you'll be pretty close I | reckon. | [deleted] | sillycross wrote: | 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. | jasonwatkinspdx wrote: | 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. | mdpm wrote: | see also felicette. | | https://github.com/plant99/felicette | jubjubbird wrote: | If you just want some nice (public domain) art to hang on your | wall: | | https://www.usgs.gov/centers/eros/science/earth-art | sci_prog wrote: | Kind of related. I used similar data to produce an Augmented | Reality version of the (almost) entire Hawaiian Island chain with | both topography and bathymetry: | | https://youtu.be/m0fB4wrvgeY | jareklupinski wrote: | so cool; seeing the evolution of the piece and thought put into | the process, from sentinel source image to wall-worthy art, adds | a lot | kepler wrote: | It caught my eye and almost bought one but then I realised it's | 2D map. The UX is misleading, at first glance I thought this was | a 3D printed map with relief. | porphyra wrote: | 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. | | http://enblend.sourceforge.net/ | darknavi wrote: | I'd love to request an area (USVI, St. John specifically). | | These look great. I love the insights on the tuning process and | it's nice to know it isn't just a lazy cropping. ___________________________________________________________________ (page generated 2021-08-27 23:00 UTC)
