ArcGIS Pro 2.6: Why a raster of 3 band resulted by the “extract band” function is different from the original layer when displaying it with same 3 bands?
ArcGIS Pro 2.6: Why a raster of 3 band resulted by the “extract band” function is different from the original layer when displaying it with same 3 bands?
For example, in the screenshots below, the original raster has 4 bands. The “extract band” function is applied to extract 3 bands (band#0, band#1, band#2) from the original raster.
Now, as the original raster is displayed with 3 bands (band#0, band#1, band#2), the visual context isn’t matching the extracted raster with same bands (band#0, band#1, band#2).
i.e, why the original raster that is displayed with 3 bands (band#0, band#1, band#2) doesn’t look like the extracted raster with same bands (band#0, band#1, band#2)?

Hi Jamal
It is most likely that the two images are just being rendered differently.
Do check whether the same stretch type has been applied (this is probably the culprit). But also ensure that Dynamic Range Adjustment (DRA) and resampling are also the same.

Thanks Mervyn
Right. They got different stretch type. The extracted raster comes with “percent clip” type while the stretch type of the original raster is “none”. Unifying the “stretch type” gets the two rasters identical in terms of visual context
