This week’s Graphics and Design tutorial focused on Noise Light and Shade Techniques. Noise in photographical meanings is the undesirable variation of brightness or colour information in an image, it is something that every photographer dreads in a shot it can be prevented with a few simple techniques. We were also taught ways in which to prevent noise happening in our images, the main one being to crank up the iso setting before you take the shot, but also to make sure the shots are well-exposed as underexposed photos are more likely to contain noise in the image. In Photoshop however, you can easily hide the colour noise contained in the photograph by making a copy layer that has been blurred, and then set its blend mode to colour, then eventually blur the detail on the layer. Possibly however, the most effective of the methods we were taught was to use a program called Lightroom with a RAW image as it addresses each different aspect of noise (Colour, Light etc) that can be found in an image.
Overall, I found this tutorial to be fairly easy to understand, as the tutorial was with taught step by step instructions. I feel that these techniques will prove to be very useful to my work, especially as a lot of the photo-shoots that I do are usually in pretty dark locations (for example, gigs and nightlife photography). Looking back at the photos I have taken, I can see that a lot of the images contain noise in one way or another, but this tutorial has taught me that it can easily be prevented with a few simple precautions. The shading aspect of this tutorial again has shown me that I can achieve a much more higher quality in my photos by making them have more vibrancy in colour, something that I will definitely use in future editing.
