I am facing difficulty converting between Sentinel GeoTIFF file and JPEG file. I used below command i.e.
gdal_translate -b 4 -b 3 -b 2 -of JPEG -scale inputimage.tif outputfile.jpeg
The problem with this approach is, that if I convert 32*32 TIFF file into JPEG and if the same patch is from 1000*1000 TIFF file and I convert that file into JPEG, then in both cases the same patch looks different in both JPEG files.
