What is white balance?
This is when you balance the temperature of an image. Using setting such as auto white balance and Tungsten e.g.
what is colour temperature?
A colour temperature is the main focus when white balancing, which is measured through Kelvins. The colour temperature changes, however, it depends on where the light source is coming from to what the contrast in colour will be and it’s about altering the temperature for the image to look correctly.
How does the white balance function on the camera work?
So there a three simple steps
- there is are varied selection buttons that are placed in a circle which is next to the screen, what you do is press the one that says WB this is another words for white balance.
- Then what happens is that a ray of different options in a line come up for example daylight,shade e.g all of these are the types of light that can be shown in a photograph and the source for example if you used daylight it will be a blue filter because this is usually used outside, comparison to shade it which is mostly used for duller lighting which will then create a different white balance the reason for this as explained beforehand is that it is measured in Kelvin which tells you the difference between each type of lighting that can either create it to blend in within the image.
So during today we done a practical task which we done through practicing ourselves how each different light changes and why we use this when filming.We used three different locations which each one had to cover each of these specifications interior,exterior and internal.
Auto white balance – Most people use this one as it is easier control because the camera does it for you and alters it to the certain colour temperature needed. I think the external one works better than the others because it is more natural looking than the others i had taken a picture of this might be because there is more light coming through the area i had taken the image from.
Daylight (5200K) – This for when there is more light exposed of that it is bright this is why some of the images I had taken had a blue tint such as the exterior and external as these are the ones that have the most brightness which then tries to match with it but can not.
Shade (7000k) – This is to use in low light to it has more of an orange temperature to dull down the scene and match it with the light around the shade. I think this went well with the interior this maybe because this is was a lower light contrast to the others.
Cloudy (6000k) – This is mostly used in exterior locations as this gives the location an equal light temperature from having less light than you usually would have without the clouds.Comparison between the temperature shade and cloudy in the external, it has no difference rather than the others only have a slight change like the interior it is a little bit lighter but not much.
Tungsten (3200k) – Tungsten is the source that lites up our light bulbs so this is the reason why it has an orange tone to the colour rather than a blue so it’s there to make the scenes lighting equal when there is the light source of tungsten in it.
Fluorescent (4000k) – fluorescent is if you want to put cooler tones to the image in daylight.
How I found the task –
I really liked doing the task so then i would be able to feel more comfortable when filming and enjoyed working as a group and trying different angles to represent each of the white balances. However at the very end when trying to upload them onto my very blog it ended up turning corrupted I’m not sure how,so instead of showing the photos me and my group created in that time, i decided to create some myself from my very home so then at least I can still show an understanding and examples about the topic.
during this task we used the knowledge we gained from the Introduction into white balancing and so we were learning more about lighting but this time about light and how it’s produced and shown through the equipment used in film and tv.
What is light?
Light is based around the electromagnetic spectrum which shows how many meters the it can go as the spectrum is between 400 – 700 Nano meters and it’s about what type of light is and isn’t visible to the human eye.
3 point lighting –
There is also something called 3 point lighting this is the design of the lighting so where each piece is going to be placed this is used to carry out different effect you have got the backlight,key light and fill light.
Backlight – This is mostly used when wanting to bring the subject out of the background with having slight light to the right or left or the subject.
Fill light – This light explains itself in the name it one of the main lights that you use to fill in the shadows instead of leaving them in with a key light.
Key light – This is the main light which is used for creating silhouettes so whether that’s filming a dramatic scene or interview.
The practical task was to practice on how lighting works with different positions of lighting through using a reflector which bounces of light to create a similar effect to what the 3 point lighting does. This was to be tested in both interior and exterior locations around the college.
Exterior – Gold
The first one is using the gold side from the reflector this gives the subject more light towards the face when placing it on the side.
This is using the same side of gold. However, positioning it from below there is a little more shadow but not much difference to the one photo taken beforehand.
The shot shown here is an above shot this gave the shot more brightness when it is above i think it doesn’t reflect as much the first as this gives you more light because the reflector is exposing it more.
Exterior – White
I believe the white side wasn’t as effective as the gold i gather this is because of the foil that creates a reflection more which allows the sun to reflect off from more comparison to the white.
This shot shows that there is quite a lot of light show on the face, however, makes the shot look equal within the light exposed. This is most lighting is probably the most balanced out.
From the side, it gives a very similar effect to the gold i used before this might be because of the position, but it does give the subject shadow.
As this is used from about this is more darker to the face than most of them this may be because below the sun wouldn’t be able to reflect off the reflector.
Interior gold –
Although this is out of focus it still show the difference between the lighting such as this creates a shadow onto the right side.
This one is using the gold reflector with it below the subject, in my opinion, I believe it make the subject pop out more from the background instead of the previous one. It did work but I prefer when the subject is fully lit up rather than having a shadow on the face.
This is very similar to the one above,it only has a very slight change in the shadowing and I feel like it doesn’t work as well as the first one which was using gold onto the side.
Interior White –
The white reflector is definitely most brighter using it inside rather than out this maybe because the area we shot in was very limited to natural light which maybe made it easier for it to reflect onto.
Above is too dull to just about see the subjects face because of how much the reflector it covering the light.
I think this photo is a bit too similar to the one above . it may have worked if there was another light so then the light on the subjects face will be more equal rather than having quite a dark shadow on there instead.
Conclusion of the task:
Overall I believe the gold side of the reflector is better to use this outside gives more brightness to the scene especially is the scene is in the shade, comparison to using the white this was good in both situation but I would mainly use this below if i was inside just so then I can let the light in a bit more.
