The exposure triangle is made up from the shutter speed, aperture and ISO of a camera, which all work together to give us a perfect exposure. The aperture is the size of the hole which light is passed through in the lens, the smaller the number the larger the opening. The shutter speed also allows us to august the amount of light coming into the camera, the longer the shutter speed the more light is allowed in. Finally ISO control the sensitivity of our camera to light, the lower the number the less sensitive therefore the less light. however the when more light is let in the image can become grainy, we call this noise. there is a meter in our camera that can automatically adjust one of these if you change another however this can change depending on the quality of light available. we usually set two of the three manually and the mere in the camera will change the other for us. we can chose which we would like to adjust depending on the type of photo we are taking.
Contact sheets are a vital and visual way of showcasing the work done both in and out of lesson, they can be created and displayed in many ways; here is the way I find most appealing and suitable.
To begin, open up Adobe Bridge and import the desired photos into the ‘content’ section.Select the photos you wish to use using Ctrl+Right Click On The Images then go to Tools<Photoshop<Contact Sheet II, this should open Adobe Photoshop in a new window.In Photoshop, you should be greeted with this window, from here you can adjust the amount of rows/columns desired and consequently, alter the final outcome.This is the outcome, I could choose to stop here and export the file as a png or jpeg or I could alter the background and spacing manually.By using the Rectangular Marquee Tool, I select the row of photos and Layer Via Cut (what this essentially does is separate the rows into layers that I can alter and move). I repeat the process for the remaining two.I then moved the layers closer and, using the Rectangle Tool, created a shape layer that serves as a black background.This is the final product, although it’s not much different from the original contact sheet the colour of the images is much more vivid and they look much more presentable.
Normally, after contact sheets are created favourite photos are selected and taken to the next stage. Contact sheets are helpful with this since you can compare and discriminate between many images at a time.
A contact sheet is similar to a negative but in positive colors. Contact sheets contain thumbnail images of all the photos from a previous shoot. This makes it very easy to look at your favorite photos that you have chosen and want to use and would possibly chose to develop or print out.
How do we use contact sheets?
You can make a contact sheet by opening Adobe Bridge and selecting the photos from your previous shoot. Once you have selected your photographs, you go to ‘Tools’ and then click ‘Photoshop’ where a drop down box will appear where you will need to click the ‘Contact Sheet 2’ option which will then open Photoshop where all your selected photos will be presented on the page in the options you have chosen.
