Alex Photography Workshop Notes and Tests

FILE TYPES:

RAW – uncompressed, large file size, must be processed after shooting, less digital noise, lossless, greater dynamic range – more colour information, deals better with contrast

JPEG – compressed file, smaller file size so faster than raw, loses data every time a change is made, noisy. Good for emails/thumbnail images

RAW PROCESSING:

When editing RAW files, changes are recorded in the metadata and saved as an XMP file.

The XMP file is saved in the same folder as the original RAW file. (The original RAW without edits can be opened without the XMP if moved to another folder or deleted.)

EXPOSURE

MANUAL MODE: PHOTOGRAPHER IS RESPONSIBLE FOR THE EXPOSURE

Exposure describes how light or dark the photograph is.

Exposure is controlled by balancing ISO, aperture and shutter speed.

ISO, shutter speed and aperture are all measured in ‘stops’.

ISO CONTROLS HOW SENSITIVE THE CAMERA IS TO LIGHT

The higher the ISO the more sensitive the camera is to light meaning you can take photographs in lower light conditions without a flash. But… a high ISO will increase visible noise in the image

WHITE BALANCE

Different types of lighting cast different colours, for example tungsten lights, the kind used in the home cast an orange colour over the subject. The white balance setting will counteract this by adding a blue to the image.

The focal length is the distance from the centre of the lens to the sensor.

SHUTTER SPEED

Shutter speed is the amount of time the sensor is exposed to light. It controls exposure: how light or dark the image is.

APERTURE

Aperture is the hole inside the camera􏰀s lens, it controls exposure: allowing more or less light into the camera and…

DEPTH OF FIELD How much of the foreground, centre- ground and background is in focus.

These past two workshops have been undeniably helpful in honing my photography skills. I have been experimenting deeply with the DSLR, learning how to control Aperture, Depth of Field, ISO, Shutter speed, lighting, framing and much more. These photos are a few examples of some different skills and techniques I’ve learned such as Rembrandt’s Triangle, which I’ve tried in multiple shots, as well as broad and outdoor lighting. I’ve also attempted some shots in the rain, night time, and with some other forms of light sources.
