Q: Sentinel-2 range of values, Level 1C (2A) Is it correct that images (TIFF 8-bit, B2, B3, B4 bands, sentinel-2 L2A, high resolution) downloaded from sentinel-hub have very poor range of values? Min value is about 30 and max value is about 60 for some bands. 
Shouldn't histogram be wider or it's normal for Sentinel data with atmosphere correction? Nir band has wider range of values. (Note: region of interest has forest cover; summer period; clouds 0%)  


A: Perhaps this FAQ entry will reveal some information:
https://www.sentinel-hub.com/faq/how-are-values-calculated-within-sentinel-hub-and-how-are-they-returned-output
As @MikkelLydholmRasmussen, these numbers correspond to reflectance values. When visualizing true color imagery we (at Sentinel Hub) often multiply them with 2.5.
If you want to avoid this auto scaling you can use the API:
