Shutter speed at 1000 sec and Aperture at f/1.8 for Portraiture,was that right to use this matter?

Answer 1

What did your camera's light meter indicate? I gather you have no idea what that is, otherwise you wouldn't have asked. There is NO way of me determining whether that was a proper exposure for the available light given I wasn't there and have no idea what your lighing conditions were. Read your camera's owner's manual. Reading is fundamental, you'll answer your own question.

Answer 2

ISO is a length of the sensitivity to easy of a easy comfortable floor, no remember if action picture or digital sensor. The decrease the huge type the less comfortable; the better the huge type the extra well-off. interior the lens there's a diaphragm this is made from skinny movable blades that could nicely be opened or closed to type the aperture or f-provide up. The smaller the huge type the bigger the hollow. So f1.2 could be very great and f22 could be very small. The aperture controls how a lot easy is admitted so f1.2 might admitt each and every of the available easy and f22 might admit little or no. The shutter speed controls how long the easy is authorized to disclose the easy comfortable floor. that's controlled by utilising the two the ISO used and the f-provide up chosen. The shutter speed additionally has a place in combating action. the quicker the shutter speed the a lot extra possibly that a runner or shifting motor vehicle would be "frozen" without obvious blur. that's a hypothetical occasion to coach the ISO-aperture-shutter speed relationship. For our applications we are going to be shooting on a sparkling, sunny day*. ISO one hundred f2 @ a million/8000 f2.8 @ a million/4000 f4 @ a million/2000 f5.6 @ a million/1000 f8 @ a million/500 f11 @ a million/250 f16 @ a million/one hundred twenty five ISO 2 hundred f2 @ a million/16000 f2.8 @ a million/8000 f4 @ a million/4000 f5.6 @ a million/2000 f8 @ a million/1000 f11 @ a million/500 f16 @ a million/250 As you could actual see, our shutter speed decreases as much less easy is admitted by utilising the smaller f-stops. f2.8 admits a million/2 as a lot easy as f2; f4 admits a million/2 as a lot easy as f2.8, etc. considering that much less easy is admitted our shutter has to stay open longer to allow the easy to disclose our action picture or sensor. * this occasion relies on the time-commemorated "Sunny sixteen Rule" which states: "On a sunny day, set your f-provide as much as f16 and your shutter speed to a million/ISO." So once you're utilising ISO one hundred your shutter speed at f16 is a million/one hundred twenty five. It replaced into created back while shutters have been mechanical. at present's electronically controlled shutters are, in result, "stepless" and can certainly gain a shutter speed of a million/one hundred or a million/2 hundred while needed.

Answer 3

for a portrait you may want to use a higher aperture as to be sure your subject is completely in focus. A 1.8 has a very very very shallow depth of field. If you are off of focus by a mere 1/2inch on a macro shot then you are in big trouble.
I'm not saying use f 22 or anything. That would make everything in focus and a bore to look at. Unless you are shooting landscapes..i.e. Ansel Adams.

Also you must have been shooting a very low low low film speed to get 1000 sec at 1.8. it looks as if you are shooting 100 iso.


maybe try 250 sec at F4.

good luck!

Answer 4

You must have been outdoors in bright sunlight. Are you happy with the results? Is your subject happy?

Answer 5

Impossible to tell.

Depends on lens, camera, distance, and the effect you wanted.

depends on the light you are using, if its strong enough then the images will be ok, maybe a grey card will help you
