For my part, the top have of the image below is the output from Rawtherapee while the bottom half was done using Photoshop. The colors in the RT version are more natural and thus closer to reality which is what I want. However, I like the heightened contrast of the Photoshop version.
One thing I’d like to point out is that the Photoshop auto contrast tool produces dramatically different results depending on whether you are working in RGB mode or LAB mode. In this case I used LAB mode to make contrast adjustments as well as initial color adjustments - then finished up in RGB mode.
Hi Ingo, wonderful job. The best of all the ones done so far and better than the Google Earth representation at the same level of resolution - which uses images from Digital Globe rather than Landsat.
Hi Ingo,
Thank you for that excellent overview of the steps you took in processing the image. I’m going to follow your outline and see how close I can get to your results.
Hi Tobias,
In order to download the full set of data for this image you need to create an account at Earthexplorer.usgs.gov. Each observation is a zipped tarball and will be on the order of 0.8 to 1.0 GB.
The easiest way to find the image is to use the path and row selection criteria. For this image the path is 171 and the row is 026. Then click the SHOW button and it will automatically fill in the lat/long parameter - as shown in this image:
The data set that you need to use is Landsat 8 OLI/TIRS C1 Level 2. Note that the GUI takes a little getting used to. You should also install the USGS Bulk Download Application for managing the download of your orders.
