That whole mess of information is not super important at this stage. It just shows what settings the camera was using when you made these images.

The first thing I would like to note is that you have achieved what the assignment asked of you. That is you’ve made something boring more interesting using your camera. So that’s really fantastic.

You’ve managed to get really close and you’ve composed the image in an interesting way.

Let’s take a closer look at the images now.

You might notice that when you look at the photos closely they look a bit noisy/murky. This is because you had your camera on Aperture priority mode on the same settings for both photographs. In this case with an ISO of 6400. The ISO is one of the easiest things to understand. Assuming all else is equal a higher ISO number just means your camera is more sensitive and a lower number means it’s less so. Why would you want your camera to be more sensitive? When it’s dark you’d want your camera to be more sensitive so it can see more. And the reverse is true when it’s bright you don’t need it to be as sensitive.

There is a tradeoff here. The higher the ISO the more noise you get. If you look at either of these photographs at 100% you’ll see they look kind of like sand. This is because you ISO was 6400 (very high).

Either you had set your ISO that high or your camera did it for you.

A workaround here would be to use a tripod and shoot at your lowest ISO given the subject matter is not moving.

Don’t worry as you learn more and practice more all of this well make more sense. For now just understand that getting close to your subject almost always makes your images better and that super high ISO means a really sensitive camera and lots of noise in your images.

You’ve done quite well here.

I would encourage you to play with your camera’s settings a little bit. Take photos of the same thing at different ISOs and you’ll see how it can impact your images.

Also remember that anything worth doing (like learning photography) takes practice. Olympians don’t become olympians just by buying the right equipment nor do great painters become great painters by buying a nice brush and canvas. It takes hard work and practice to become a good photographer.

Good job and see you on the next assignment!!!

Thank you
