Photography 10

Image Critique #4

This is a photo I took for my Story in Three Frames assignment. I was very proud of taking this photo because it is so clear and there is barely any movement from the ball, which was captured at just the right moment due to the high shutter speed. This image is slightly underexposed, and there is contrast from the orange hoop and basketball, against the blue sky. Colour theory was used because both blue and orange are complimentary colours, meaning they stand out when put together. When editing this photo, I lowered the exposure to make it less bright and it almost feels like you’re playing basketball on a hot, sunny day, wearing sunglasses due to the lowered exposure. Hard lighting has been applied because it was very sunny outside and the sun naturally cast hard shadows, which is visible on the bottom of the basketball. Although this photo is nearly perfect, it does have some technical and compositional weaknesses. While editing the photo in Adobe Lightroom, the scratches and marks on the backboard of the basketball hoop could have been removed using the eraser tool. I also wish that the shutter speed was a bit higher because when you look closely, there is slight blur from the movement of the ball, and if there was completely no blur it would’ve improved this image a lot. To improve upon these weaknesses, I would have to increase the shutter speed, and either lower the aperture or increase the ISO because this photo was shot in manual mode. I could also edit the photo and remove the imperfections and marks on the backboard, but that isn’t as necessary because they add character to the photo and keep it looking natural. Overall, I am very proud of taking this photo because of I captured the perfect moment of the ball going into the hoop, and because the image is so clear and the colours look nice together. 

Titration Lab Self-Assessment

A titration is a laboratory technique used to find out the exact amount of one substance needed to react completely with another substance. The purpose of this lab was to use titrations to determine the exact amount of NaOH needed to neutralize HCl. The endpoint of a titration is a point in neutralization when we have fully neutralized the HCl, and we can keep tract of this point using the burette that contains the NaOH. To determine whether the endpoint has been reached or not, we can tell by the colour of the substance. The phenolphthalein in the solution helps us in this procedure, as whenever NaOH is added to the HCl, it turns pink in the solution as bases turn pink in phenolphthalein and acids stay colourless. It changes from transparent to faint pink when the base neutralizes the acid. The light pink color stays for about 30 seconds which shows that the endpoint has been reached.

Core Competency Self-Assesment

Communication

While working with my partners during the titration lab, I used communication to help us stay organized and work efficiently. We discussed each step before doing it to make sure everyone understood the procedure. We also made sure that we were all contributing to the lab. I communicated clearly when reading measurements from the burette and when watching for the color change, so we could stop at the right moment and not end up with a solution that was too pink. We also gave each other reminders to be careful and double-check our results. By working together and sharing ideas, we were able to complete the experiment successfully.
