Hi, I used 1/125 f-5.6 for indoor of portrait with normal room light, and I just got my photo and it turn into yellow colour so is that because of my setup wrong way??
Thanks

The yellow color on your photos was caused by the interior light, not the f-stop of your lens. Most regular film was 'balanced' for daylight and flash use. If the film is used under fluorescent light, the photos will get a green cast. If use under tunsgen light, a yellow/orange cast. You can use flash to lit your subject. You can use available light by putting your subject close to a window. You can use filters if you do not want to use flash or there is no available light. Use the FL-W filter for under fluorescent light and 80A for other lightings. When using filters, you have to open up the aperture to compensate for light lost. Read the instructions that come with the filter. Hope this helps.

I almost forgot. There are films that are balanced for tungsten light from Kodak (usually with the 'T' postfix). Look under the Kodak web site and you should find them.

A couple additional notes: Household incandescent lights have tungsten filaments, hence they are a form of "tungsten" lighting. However, if you use a tungsten-to-daylight filter, or tungsten film, it corrects most of the color balance but not quite all of it. The filters and film are intended for studio tungsten lights which are much higher wattage and have a little more green and blue in them as a result (comared to 60-75 Watt household light bulbs). Even so, Andy's suggestions about filters and film will make it much easier for your print processor to get a much better color balance in your prints. The only tungsten balanced color negative films I'm aware of are ISO 64 and ISO 100. They're all professional films. This is rather slow for indoor household use with 60 or 75 Watt incandescent lights. The fastest tungsten film I know of is Kodak's Ektachrome 320T, a slide film. Even this speed is at the low end of being fast enough to use with household lights. Additional suggestion:
You can shoot B&W film under tungsten and fluorescent lighting and not worry about color balance. The shades of gray rendered by some colors will shift slightly, but not much, and they will still look natural. There are some fairly fast B&W films too. It's an alternative to consider. -- John
