Great post, good for us newbies who are trying to explain simply what the different elements are 🙂


Nice infographic. Perfectly summarizes the basic exposure settings a newbie should understand.


Thanks for the post! I just bought my first dSLR and it’s all Greek to me!


Best advice given to me when I wanted to learn exposure- set your camera to M- Manual Mode and keep it there. Go out and shoot the same object with different exposures to see what a difference the ISO, f-stop and shutter speed can do to your image. Also, invest in a 50mm lens if your DSLR has a full-frame sensor, so you can learn how distance can distort your perspective, especially if you plan on photographing people. 🙂

ISO has nothing to do with exposure. It certainly doe not increase the sensitivity of the sensor. Only shutter speed and aperture determine the exposure i.e. how much light reaches the sensor. The sensor has only one sensitivity, the base ISO. After the shutter closes and the photons in each sensor well create electrons. The signal gain can be increased before it is digitized. Of course this can not increase the exposure because the data recording is step is over. Both the signal and the noise are increased by the amplification. Increasing ISO does let you under expose which can… Read more »
