Question on ISO Setting.......
Hey Everyone!.

I'll try my best to give you all the info to help me out!.

I'm taking pictures of PEOPLE..

I have a Nikon D40 (Not D40x) with 18-55mm lense.I have a home studio with 2 / 500 watt lights/umbrellas. Also 1 backlight..

ISO Sensativity currently at 400.Camera is in Apature mode..

Basically, if I go outside, my apature bumps up to say 125. I'm having trouble maintaining a higher apature while indoors..

Also, I have my models get as close to the lights as possible with them interfering with the photos!.

Any suggestions on ways to bump up the apature inside ? .

Let me know if more info is required to answer.Steven SchuylerSKYLERFOTO..

Try Manual mode at ISO of 200, aperture of f8, and shutter speed of 1/60th and see what happens. You may need to make adjustments from that starting point. I'm an amateur, so maybe someone who has used the specific kind of lighting you have will jump in with better ideas..

I don't think that's your aperture. Sounds like your shutter speed (1/125th of a second)...

I'm not saying this to be mean or condescending, but you really need to learn the difference between aperture and shutter speed before you do anything else..

From there, study up on exposure, exposure compensation and metering...

It's not clear what aperture (lens opening) you are using. At ISO400, if you are getting a shutter speed of 1/125 sec outdoors, you must be using a fairly narrow aperture like f/11 or f/16 (remember a bigger number = a smaller aperture which lets in less light). So it's not surprising that indoors in much poorer light you would get a very slow shutter speed..

Set the lens to it's widest aperture (the smallest number, which will be somewhere in the range f/3.5 to f/5.6 depending on the zoom setting) and try again. With a brightly lit indoor scene, if the lens aperture is wide open it should be possible to get a reasonable shutter speed (say, 1/60 or faster) at ISO400. if you are still getting a too-slow shutter speed you could increase the ISO to 800. I have used ISO800 regularly for indoor portraits and the image quality is excellent..

Best wishesMike..

In some of your gallery pictures you seem to be mixing on-camera pop-up flash with what light the tungsten floods are giving you. Judging by the shadow on the background, the pop-up is winning! When the flash is up, the in camera metering modes change to take it's light into a account, so your description becomes wrong..

There ARE ways of blending flash and continuous light sources together, but until you get past the rank beginner stage, I don't think you should do that..

Do this instead....

1) Turn off the pop-up flash completely.2) Set your ISO to 400.3) Set metering to Aperture priority.4) Set aperture to f/4 or f/5.65) Hold the camera steady or use a tripod, and tell your sitters to HOLD STILL..

6) Set your main light a foot ABOVE sitter eyelevel, and place the fill above camera. Presently you are shining light from under their chins, which is not a good look..

7) Now start practicing like mad until you can really make those lights work for you, and for your sitters!!.

Alternatively, consider chucking out the tungsten lights and getting some studio flash. Alien Bees are well regarded in your part of the world. Flash will freeze motion in your subject and allow you to work with a hand-held camera without motion blur..

You really need to practise and improve before trying to sell your pictures. At present your skills are at stage 2 out of 10.Regards,Baz..

It looks like you're doing some things "right" and have a number of models and clients. It appears, too, you have already received some suggestions and criticism, so here's some more..

Go to the library or various sites here online and learn more about photography and lighting in general..

For some of your portrait work, consider a longer focal length such as 90-110mm..

If you can't learn to spell apature (aperture) then say lens openining.

You either need a lot more light, or you need to switch to a flash set up. 2 x 500 W is nowhere near enough..

I have 2 x 250 W tungsten halogen lights which I use for 'table top studio' work, lighting small subjects with the lights maybe three feet away. I have to use quite long exposures, but it doesn't matter because the subjects are static and the camera is on a tripod. Even with twice as much light, as you have, I wouldn't expect to have enough for successful studio portraits...
