Here’s a summary of my notes during the lighting and camera fundamentals class
Exposure is the quantity of light allowed to reach the photographic film.
Sensitivity,ISO,film speed is the sensitivity to film. The more sensitivity the more grain etc.
Aperture is the hole that allows light to reach the sensor.
Shutter speed is the amount of time the light is allowed into the camera. 1 over 50.
When aperture is low, shutter needs to be longer in order to catch.
Human vision vs camera lens
40 degree lens create more human presence than a wide angle lens. Therefore adds a more viewing.
Lmask allows you to see the viewpoint when scouting.
Focal lens allows you to zoom in and focus on an area.
Colours become more intense when you bring the aperture down. When working with textures such as pearls and velvet they will suck the light to them.
Look at lab colour language. Universal colour language. Raw is lab. Look at black magic cameras.
Depth of field. Aperture changes the depth of field. A quicker shutter and high aperture creates a stronger depth of field.
Funel light ➡️ same light I use to create a rim light effect.
Cant change aperture without compensating in shutter speed.
The longer the lens the more shaking you’ll see. Wide angle lens can create barrell effects and are best used from below looking up. Tilt shit lenses.
Compression in photographs based on angles as you move up and down. Don’t focus too much on zoom always walk around the subject to figure out which one is best. It’s a better disapline.
Using the space to compress things in best way to capture the action. Eg. Wide angle might work to catch the vast openness of the scene.
Soft box creates a soft light unlike a flash which is a harder light. Bouncing is the softest type of light eg. The use of a reflector. The use of work lights that hang can be used to capture eye makeup. In some cases the shape of a light is important in cases of reflective textures.
Lighting wotage determins the colour 4300-4700k is roughly neutral light. 800k is red. 12-20,000k is more violet and blue. This should be considered when artificially lighting a set that all bulbs are the same voltage or else the use of coloured gels to keep consistent. If not neutralised colour will fill the colour of the shadow, if a red tinted and blue tinted are the used the lesser of the light will tint the shadow. If the blue is the bigger light the shadow will be a red tint unless reflected back out.
All of this will apply the same when rendered properly out eg. In Arnold this will be effected.
Spot lights and flood lights. A funnel lens focuses the light this narrows the spill of the light. Spot light is a direct circle of light but a flood light is a larger circle of light.
Bouncing - can be used with umbrellas (like me!)
Diffusing - using a white diffuser to slow the light down as it travels. Can then aim the light at the object overall making light more focused and much softer looking.
Coverage - different heads can be used to create different coverage of light.
Intensifying - adding a black reflector will increase the shadows.
Size relative to the subject. Closer light sources become softer. Sunlight is harsher because it’s direct not diffused. Closer light sources illuminate the subject more evenly.
Annie libwitz - photographer that can create even light sources. She uses a massive light box. Fills and floating lights, Matthews lights.
Light closer can create a really lovely contrast in the image.
Shapes of light
Polarise makes light move through reflection. It takes reflection away, intensifying shadows and reduces highlights.
Martin parr - super important photographer
Reflexive draws attention to the fact the camera was there.
