I do not know what your green background looks like
your bottom picture is bluish green whereas your photoshop is yellowish green ( I painted on silk for 8 years )
If this is the true color (your photoshop) then you have a blueshift due to whitebalance problems
If your camera can do whitebalance calibrating you should get a 7% greycard at any photoshop ( brick and mortar one)
I was too leazy so I bought 3 full spectrum light (saving) bulbs in germany with a known daylight of 6000K
I set on my canon 6000K and couple the canon to the computer for vibrationless release ( by mouseclick) and immidiate viewing
I use creative auto ( this means the camera proposes a shutter opening and a time like 1/100 seconds at 5.6 dia and allows then to rotate thru all equivalent settings ; for dept I allways go to the highest number preferably 11 diafragma if I still get 1/30 seconds
- the camera is on an alu stand - )
I think the last picture ( full auto ) would sell best on ebay
In my personal opinion all pictures could do with more contrast ( black and white balance ) but that is a given for
all coinpictures before photoshopping
So point and shoot looks best
