The Green Field




This is the same green field as the one taken last Sunday, east of town by the Lumix Digital.   It was taken from the same vantage point but because the Lumix offers wider aspect ratios, the film version "gets in less".    But in terms of color tones, the raw digital version was closer to the film version (shot in 400 ISO Fuji Colour).   Both the digital JPG and the (scanned) film version require color/tone corrections.


Rosco felt that the original digital JPG (upper left)  was too dark, so he pushed on "auto color" and "auto levels" to "lighten and brighten".  Because Rosco hasn't gotten around to buying a UV filter for the Nikon, his film pictures tend to have a reddish/yellow tint which need to be corrected (lower right).

Rosco learned a new way to color correct in PhoShop, today. Previously he was fiddling with slider bars individually adjusting the four (or three) primary colors. This was very time consuming.  As it turns out, both the "levels" and "curves" tools have three eye dropper tools which can be used to "correct" the picture depending on what part of the picture the cursor points to.  

Use the black dropper to designate the spot in the picture to be set at "black" and everything else will shift and be set accordingly.  Ditto for the white dropper. For general spectrum tone correction use select the grey dropper and click on that point of the picture which is grey, off white, dark grey (or anywhere else if you want to be naughty).

Wonderful thing is you can spend hours clicking and tinting... sorta like chewing mindlessly on a bone.   There is no right answer.  Rosco thinks that all of the above pictures aren't sufficiently blue.   

Accepting what humans see, Rosco thinks that the digital JPG is too tutti frutti and artificially lime green...although luminescent lime green is nice.  Although the sky could possibly be a tad bluer, he thinks the adjusted film is most natural looking. 

But he's just a doggie and what does he know?
