EDIT:
This lot are all intended to be user configured,
Code:
LockChan = 1 # Chan for lock to Ave, 0=R, 1=G, 2=B
# -1 = Use LockVal below.
# -2 = LockVal=(RedAve+GrnAve+BluAve)/3.0 for LockVal.
# -3 = LockVal=Median(RedAve,GrnAve,BluAve)
Th = 0.0
LockVal = 128.0 # Only valid if LockChan == -1
Show = True # Metrics
Verb = 5 # Verbocity FULL
DITHER=FALSE
x =0 # Coords (for dc Detection Clip)
y =0
w=-0
h=-0
omin=0 # Output channels minimum (footroom for manual editing).
omax=255 # Output channels maximum (headroom for manual editing).
#Return GamMac(DC,x=x,y=y,w=w,h=h,Coords=True) # Show Coords only
Scale=2
RedMul=1.0
GrnMul=1.0
BluMul=0.95
Scale=2, is a very ferocious setting,
you could also try eg Scale=1 (or Scale=0), and recommend change BluMul=1.0 (0.95 was specific to the Church image result which is too blue).
EDIT: You could also try Bernardd's automatic White Balance script:-
