The Snake River has begun its annual runoff with the resulting high water, tons of debris carried down river and so on. I went to the actual Falls of Idaho Falls yesterday afternoon to see what photographs I might take of the runoff.
From the bridge crossing the river on Broadway Street in the downtown area I spotted this Cormorant swimming along the river before it went over the falls. I got a decent photograph from a long distance with my Sony RX10IV using 600mm. I took some other photos far off up the river of the Mormon Temple and then took a look back at the Cormorant. It was standing on top of some log debris with its out stretched wings doing the Bald Eagle routine of being our National Bird. Then came numerous photos of this Cormorant doing the Bald Eagle routine. I hope you like these.

My point is that in geneeral when one reduces the size of an imalge, one loses pixels and therefore loses information. This loss of pixel information means that reducing the size of an image always leads to reduction in detail if the photo has detail to begin with. Only in rare cases of blank areas of a given color will nothing be lost.

Note that this loss of pixels can never be rreconstructed with accuracy since there is always many combinations of pixels that can result in reduced pixels.

Here is a simplified illustration, an 8 x 1 pixel image, showing this loss of information from the reduction in the number off pixels. --Richard
