Technical Tips

• To change lighting you can adjust the aperture (smaller=more light), increase ISO to max of 3200 or change environment lighting.
• To create chiaroscuro reduce ISO and the distance between the light and the subject and make sure white balance is on auto.
• 90D top end 4K resolution with faster focussing and better low light performance
• Create proxy files to handle large 4K files in editing.
• Set to C1 mode for 4K filming.
• There are 4 types of focus on the canon cameras: face recognition, spot AF, 1 point AF and zone AF. Use magnification with manual focus to perfect.
• Practicals are in set lighting and can help film look more natural.
• Back lights establish depth and provide definition to the subject.
• The gold or silver reflector bounces light.
• The diffuser or sort box provides a surface in front of the light source to diffuse it.
• Aim for -12DB for dialogue to prevent clipping of sound.
• A wide focal length is 10-35mm, a normal/standard is 35-70mm and telephoto is 70-1000mm.
• A human's natural focal length is around 47mm.
• Continuity editing is an editing system to maintain the time and space of a film through shots.
• Parallel action or cross cutting is cuttin between 2 or more related actions occuring at the same time but in 2 different locations or points in time.
• The 180 degree rule explains the ability to do record at multiple angles in a 180 degree arc.
• An establishing shot is a large shot which provides context to the setting.
• A reverse shot is typically used in conversations between characters to show the opposite angle.
• Matching eyelines is a technique similar to a POV shot and involves matching the actor's eyelines when looking at something.
• Cutting on action is when a cut in a film is made in the middle of an action to offer a different perspective.
• The 90D Canon DSLR sensor is 22.3x14.9mm.
• Compared to a Camcorder a DSLR has a mirror, is designed for photo and video. Camcorders have a smaller sensor and zoom lens which is not interchangeable.
• A full frame sensor is the full sensor whilst a small/cropped size sensor is cropped in and smaller. For instance a 50mm length with 1.6x crop factor appears like 80mm.
• A low aperture lets more light into the camera and produces a shallow depth of field with more blur.
• A high aperture lets less light into the camera and produces a deep depth of field with less blur.
