Shooting the other night - I noticed that I was getting images from my K-x that looked very saturated.
Now Pentax dSLRs used to have a reputation of giving very saturated images on their default "Bright Color" setting
eg: from
dpReview on K100D:
"
The K100D's color response was quite similar to that of previous Pentax digital SLR's, that is quite highly saturated (vivid) in the default 'Bright' image tone, as can also be seen earlier in this review, it can lead to color clipping in certain situations (such as red flowers in direct sunlight). Switching to the Natural tone calms color saturation to more typical levels (compared to other digital SLRs). "
On the K100D I have Natural Color set.
However with more recent Pentax dSLRs like the current range of K-x and K-7 -
from
dpReview on K-x -
"
The K-x produces an almost identical color response to its bigger brother, the K-7. As we've seen in other reviews the standard hues are also very similar to most other SLRs in this class, with minor saturation and brightness differences but essentially the same color response. "
So with the current Pentax dSLRs like the K-x and K-7 the saturation is in line with most other competitors.
Having experience with the K100D - the first thing I did was to change the default Bright color setting on the K-x to Natural -
but the reduction in saturation was enough that I soon switched back to "Bright" as it gave me pictures more the way I wanted them.
OK back to the other night - here's an example of what I mean:
EXIF still attached (caveat - PhotoBucket often mysteriously drops metadata) -
only adjustments was to resize, brightness/contrast and standard sharpening -
this looks way over-saturated to my eyes -
so much so, for my posted version I had to reduce saturation by -24/100 in my photo editor PhotoImpact 8 (-100/100 would produce a black and white photo - ie: all color is removed) -
That photo was overall over saturated - however other than magenta (please see:
Modern LED Stage Lighting & photography problems ) - I think a lot of problem stems from saturation of Red -
compared to a shot taken only seconds apart on my Canon G10 compact -
notice the face of the bass player on the right of the picture, and drummer in front of the red lit screen in almost merged with the screen.
The Canon G10 seems to show reasonable details in the faces - yet the K-x picture appears to have over-saturated on the red leaving very little detail in the faces.
I tired to reduce the saturation again by -24/100 -
it is better, but the faces details are not really revealed.......
A shot from further back show a different treatment of overall red -
K-x "as is"-
Canon G10 -
K-x reduce saturation by -24/100
some really strong lighting -
K-x "as is"
G10 -
K-x reduce saturation -24/100 -
again the red in the face of the drummer on the right is never revealed -
due to the over saturation in red.......
I also tried using "Natural Color" setting for reduced saturation - but it did not seem to help that much - at least when reviewed on the K-x LCD monitor.
