Thats better friend,
As for the filters asked above, with a 35mm and using artificial light, 80b would be a better choice, even so, it wouldn't be perfect. With a digital, these filters are in fact (Or should be) built in to the camear, all you need do is programme it. A much better way to take photo's in a railroad room with either 35mm or digital is to have Daylight Fluorescent Tubes. Not Cool white, as these are not good enough. My tubes are Phillips TLD 58watt, and I have 8 on the ceiling. These are a perfect match for daylight at around noon. Colour temperature changes with the Sun from morning till night, but around Noon it's ideal for photography outdoors, and a little overcast. Direct Sunlight will burn out any photo's unless the Sun is behind, and even then I would use a flash for fill in.
