Aperture priority and reciprocity

Aperture priority and reciprocity
Hi Sudhir,
gd evng. just wanted to seek your help in understanding the reciprocity in a situation of taking a building elevation shoot. I tried this morning about 7 for a project of building elevation (my business) and I did it all in aperture priority mode. The aperture was kept at F8 and ISO was in 100 as I was outdoor, shooting the building. Every-time, the selected shutter speed was 1/8 or 1/16 and I knew that, the slower speed will hamper in the quality of images as there shall be shaky images. I should have used a tripod otherwise to get a good and sharp image. Now, in the theory of reciprocity as you say in your class, can we play increasing the ISO to get a desired faster shutter speed to create a sharp image. Don’t you think the images shall have more grains or noise with the increase of ISO? What should I do please suggest out of your experience.

Hi you didn’t mention what focal length you are using on what type of sensor, which decides DoF for selecting f stop.

It’s 16 in APSC sensor (Nikon z50). So it’s 24.

Hi. You’ve to enter the right iso to get your desired shutter speed. If the subject is Statics, no movement is there. Then shutter speed 1/50, or 1/10 or 1/2000 shutter speed get you same results with the constant exposure value +/- (must use tripod for very low shutter speed like 1/10 or 1/50) and if the subject is moving then you’ve to increase your shutter speed by increasing the iso. When you get the the desired shutter speed what you want then stop the increaseing iso. Yes, high iso creates more noise. Every cameras have their different iso performance. Crop body creates more noise compare to full frames.

There’s two way you can increase incoming light in aperture priority increase ISO or lower the f value. play around with this.
Test your camera ISO noise level then you can judge ISO settings for different lighting condition’s.
still not getting clear pic, set ISO to auto.

Yes, to achieve a faster shutter speed, you have to increase ISO. Depending on what is happening the scene, you can decide what shutter speed you need. Using a tripod is the best thing to do.
In my course I explain about shootable ISO from a camera. You need to find out about that for your camera and decide till what ISO you can go up.
