Sentinel-2a rgb satellite image of area around Lochinver in NW Scotland. New tool was using new #gdal application for initial process then #GIMP for colour correction, saturation and sharpness. New discovery that GIMP can save GeoTIFF images. Images show before and after. I think I need to work harder at colour correction - it's too green and still rather dark.
Data downloaded from Copernicus Browser - https://browser.dataspace.copernicus.eu/.
#30dayMapChallenge Day 17: A new tool.

RGB satellite image of area around Lochinver, NW Scotland after colour adjustments in Gimp. Colour correction, saturation and sharpness. Clearer than unprocessed image but I need to practice more.

To follow up - this video by Jess Zimmerman is where I found out about GIMP preserving metadata for GeoTIFF - https://www.youtube.com/watch?v=92XvGHKnqVc
Basically, Export as tif and click the Save GeoTIFF data box.

GIMP for QGIS (especially GeoTIFFs!)
