Description

Exposure Assistant is a handy photographer's utility that helps calculate correct exposure settings for those times when the in camera exposure options are not flexible enough. It is primarily beneficial in two situations:

- DETERMINING LONG EXPOSURE SHUTTER SPEED VALUES: Most modern cameras will not calculate shutter speeds greater than 30 seconds. Most of the time this is not a problem, but what about those times where you have set up your tripod at dusk to get the perfect shot, you've set the ISO to 100 for maximum quality, and the aperture to f/16 for maximum depth of field. All of sudden your camera is flashing "30" meaning that the shot will need a shutter speed longer than 30 seconds, but your camera will not do it automatically. In this situation, with Exposure Assistant you can switch to a full auto setting, input the values that the camera calculates and then enter your desired F-stop and ISO. Exposure Assistant will calculate the appropriate shutter speed. You will have to use the 'bulb' (B) setting (and a remote switch of some sort), but you will not have to guess how much longer than 30 seconds the shutter speed should be.

- USING AN OLDER CAMERA WITHOUT A BUILT-IN LIGHT METER: Though most of us primarily use digital cameras these days, inexpensive medium or large format photography using older film cameras is still a very viable (and much less expensive than digital medium format cameras) option. But many of these cameras do not have a built-in light meter for determining exposure settings. An easy way to overcome this is to use a small digital camera to determine the correct exposure settings for the older camera. Unfortunately the available settings on two different cameras (especially cameras from different decades) often do not neatly line up forcing one to do some quick calculations to adjust between the two. With Exposure Assistant you enter the basic exposure settings as determined by the digital camera and then it transposes those settings for you to values that are available on the older camera.

Nice app, needs improvements

:
I got this app to use with an old Yashica rangefinder that doesn't have any automatic mode and you need to calculate correct exposure based on EV number that the camera provides you.
This app lets you change all the values, aperture, shutter speed and ISO, and it gives you a EV based on these parameters. Sadly, the software doesn't let you select the EV number, so you basically you have to keep changing the values until you get the right EV, the same that my cameras gives me.
Some light meters gives you only the EV value, and it would be great to have the option to calculate the right exposure based on the EV value.
Still this app does the job, but I'm looking forward to and update that gives me exposure based on EV.

5/5 stars

Excellent for night photographers

:
Imagine this situation: you're in the middle of night somewhere out there and you want to take technically quality photo of that stuning night scenery. You will probably need to find out how set the exposure setting on your camera, because it'll probably be exposure of one minute or longer... so, how to find out the right time to got correctly exposured picture?

First of all, you have to compose and focus. Then set the highest ISO and lowest apperture and try exposition of 5 secs in BULB mode. Pic is too dark? OK, go to 10 secs. Exposured correctly? Right, but you have ugly (because of low apperture) and noisy (high ISO) picture. So how to get a better one? Easy!

Run Exposure Assistant. Put ISO1600, f3.5 and 10 secs into 'current camera settings'. Then set ISO100 and like f8 in 'value you want to calculate'. App will calculate you time of exposure 14 minutes. Oh, maybe this is too long, so set ISO200 and f7.1. Now you got five minutes exposure, but still no noise and good technical quality, so put your camera into this settings, set five minutes on you timer and shoot!

This is how I use this app and I rate it 5/5, because I was looking for something like this for very long time.

Less stuff to cart around

This is great I no longer need to cart around a chart to help figure out what settings I need on my camara
