Chris,
I decided to experiment. I set up the E-510 with the 14-54 and put up an image of a blue iris on the screen. I then photographed the screen (hand-held) in normal program mode. I then selected Picture Mode and used Black and White, Orange Filter, and Red Filter. My only post processing was cropping and resizing. Here are the results:

This only works with jpeg images.

Hope this helps.

Chris,

I just pulled out my E-510 Manual to check the filter comments. On page 61, under Picture Mode, the uses of the built-in filters are covered, but very briefly. While it is not specified in the text, I believe that the Picture Mode is just like any other art filter, and can only be used with jpeg images. I recall playing around with this some years ago, but have not used the E-510 recently.

I believe that, if one goes to the RAW image, the filter effect is gone.

Shooting manual doesn't mean anything with respect to WB. Or maybe I misunderstand what you mean. Did
you adjust the WB by hand using a card?

No, I simply used the preset 5300K setting. You can change the colour temperature to compensate for excess yellow (setting sun) or excess blue (clear daytime sky) internally, similar to using 81 (warming) and 82 (cooling) glass filters. I've used both but I prefer the glass as my judgement is oriented in that direction.

Anyway, a color filter on a color sensor will be a challenge for the in-board and the post-processing
software even when shot in raw.

OTT What on earth is an internal red filter if I may ask ??? Is it physical filtering? Red glass between the sensor and the lens?? We had one of these E510s (stolen) and I never saw anything like this on it.

No, it's a software process between the sensor image and the memory. Something in that process is not working as it should.

Well I think it all boils down to : What do you actually want to achieve?

I want to be able to use the internal emulated colour filters with the same ease and judgement as I've used glass ones with film in the past.
