A fun way to learn about Exposure


Hey, I just came across this app that looks like it’s been around a couple of years but it’s still a great way for you to learn about Aperture, Shutter Speed and ISO.

You get an interface with three tabs Learn, Play and Challenge so let me unpack them a bit and hopefully convince you to check out the site (no, I don’t make anything from this, I just think it will help you).


Here you’ll get some pretty basic explanation of what Aperture, Shutter Speed and ISO are and how changing them will effect your photo in different ways. You also have a link to 101 training and tips which are again basic (for me) but I recommend you have a quick look at least.


This is the fun part. you get to adjust the three variables above and take a photo to see how it came out. The trick here (as with real photography) is to check the needle at the bottom and make sure it’s in the middle and therefore giving a good exposure. That said, why not not deliberately over or under expose a photo and see how it comes out.

You can also change from Manual to Aperture Priority or Shutter Priority modes and there’s a subtle link explaining when and why you might use these options.


If you’re feeling confident why not take the challenge! I’ll be honest, I only got a score of 5 out of 6 lol! Actually, I think they’re wrong and I’ll be telling Mr Canon! Q6 asked me to make the propellor look still and apparently my chosen shutter speed of 1/1000 wasn’t fast enough!!! I think I’ll have to find something of similar speed and prove them wrong… not that I’m competitive but I have my dignity to uphold.


So there it is, have a go and PLEASE let me know what you think by commenting below, and if you take the challenge see if you can beat me, although I’ll want a screen shot to prove it 😉

    cool tip, really helps to understand the relationship between the three main elements of exposure

    It’s a great cheat sheet, for want of a better term.
    When your camera is on your tripod it’s so much easier to mess around with these settings.
    Keep it focused on the same point and you will be amazed at the difference.

    Sunrise and sunsets are my favourite times to do this, with a few clouds to bounce the light around
    I was messing around with all the settings, ISO, aperture and shutter speed.
    I took around 12 gig in RAW, I changed it to the black during the minor editing.

    When I arrived on site at sunrise it was overcast with fleeting glimpses of sunlight through the clouds.

    The colour shot was taken in England back in May after celebrating me mates birthday….. And we were on the way back to the car, had the camera with me, ohh look at that, I have used it as my front cover page on my photo album I had printed up.

    So in summary, just get out and do it, enjoy
    Thanks team

    Hi can I please ask I own a Nikon D3200 how do set it up to overpower ambient light so the only light is from my off camera flash, I have seen a video which said you should set you camera in manual to the sync speed which is 1/200 sec I want to shoot at f8 (using the kit lens 18 – 55) and an ISO of 100 in the video there image was black but in mine i can clearly still see things what am i doing wrong?

    • Have you actually taken the photo at those settings or are you looking at the screen? You will be dark at those settings assuming you’re indoors. Are you sure the ISO isn’t on auto? Please take a photo and post it here. If you’re after total darkness and you’re still getting some light you’ll either have to increase f8 to a higher number or close a curtain.
      If you need help with the off camera flash I have a tutorial here – https://www.udemy.com/flash-photography-101/?couponCode=SLR
