    Just practicing with a home made gel. I cut a 4x6 square out of a yellow Forever21 shopping bag. Then i loosely taped it in front of my 430EXII and put it in a softbox.

    The "gel" was pretty thin and light diffused pretty well, but it just made the picture totally yellow. Like something I could have totally done by changing the WB.

    This is my first time using a gel so i expect the typical OT rape without lube.
    But what I am doing wrong? I'm thinking more ambient light with a lower flash power? Or do I need a 2nd light source that's clean (without artificial color)?

    I think you miss the point of a gel.

    The purpose of a gel is to match ambient color temperatures with your flash temperature, so that when editing you have a direct match of color temperature to change the white balance as a whole instead of two pieces.

    What i mentioned is the primary use of a gel. there are other uses, but none that are directly required for the outcome of a photo, you can use gels to add colors here and there etc.

    anyways, what is the purpose of you using a gel? why do you want to use it?

    do you have two flashes?

    if you use the gel on the whole scene the whole scene will be gel colored.

    try using it on only part of the scene

    Maybe you should do yourself it by putting it on different parts of the light diffuser so only some of the light is affected by the color. Either that, or will just cast a slight shadow/dark area.

    you can still light the background with the gel and use ambient for the main exposure.

    just control the light so it doesn't hit anything but the background

    gels are either for color correcting, you use specific colors to balance your lights to existing.

    or you throw up whatever color you want, usually this is done on the non-subject part of the scene, like the background.

    since you only have one light, try this:
    throw a deep red gel on your flash, put it behind her, rake it sideways against the wall. try 1/16 to start.
    bring a lamp close to her face, up high about 45 deg, but out of the frame.
    set your white bal to whatever the lamp is. expose for the face, and then dial up/down the background about 1 stop more.
    keep this a head & shoulders shot
    post the result.

    What were you expecting to happen, the light turn purple? Yellow gel + flash = yellow light.
