He wrote that a lot of people thought his work was illitations [misspelled mean doing work for Magizines to show something] and not work of art. He did a lot of the Cuba war and stuff like that. Plus people say he used the same colors in all his work. If you look at them it is mostly the same colors in the shadows and sunlight too. He say he use them like this for that is how the colors are in the west. He wrote down what colors to use and where. The colors I guess he could have change when he was in Cuba for the colors would have been diff? I guess at this for the land would be more greener.  When i was out west for the two weeks I did noted the colors was the same as Reminton's. 
I saw this on the Doc. channel one day. That channel have a lot of shows on painters and photographers   and film makers
In other words I guess he listen to what people say about his work. I know you need to listen but sometimes you need to do what your heart tells you

what you see is not what you know; it in your face
