@pentaxpete Pete, does a Y/G filter in such a scene make no difference so isn't needed or does it make some things worse and if so what is worse here or to put it a less negatively, what would be better without that Y/G filter? Thanks
Some folks are fussy about little things... In my case I knew that Yg was pointless...
In the the rush of the moment, I was not going to lose time removing the filter and adjusting the camera filter compensation bias. Shoot it while you can... simple & fuss free...
