Today i’m gonna do a short video on color profile settings for my CanonM50. By default there are some stock color profiles that come loaded on the CanonM50,

• Auto: Sharper, more contrast, more saturation, will adjust the colours to look vivid, especially blue skies, greenery and sunsets. As such it is particularly good when shooting landscapes and outdoor sunset scenes.
• Standard: Provides crisp, vivid images with increased saturation, contrast and sharpening. Default on EOS DSLRs.
• Portrait: Optimizes skin color tones and saturation. Reduces edge sharpening for smoother skin texture.
• Landscape: Produces punchier greens and blues with stronger sharpening for crisper-edged mountain, tree and building outlines.
• Neutral: Has lower contrast and saturation than Standard. It is therefore ideal for images you intend to post-process by selectively adjusting the color, saturation, contrast and sharpening of individual images. 
• Faithful: Similar to Neutral but produces images that are colorimetrically almost identical to the actual colors when shot under standard daylight conditions (i.e., an average color temperature of 5200° Kelvin.)
• Monochrome: For black and white photos. Also includes four optional B&W contrast filter effects (yellow, orange, red and green) and toning effects (sepia, blue, purple and green).
• Fine Detail: The default [Saturation] of “Fine Detail” is similar to “Standard” but the default [Contrast] is set lower than “Standard”. “Fine Detail” has Sharpness’s [Fineness] and [Threshold] both set to the minimum of [1], so even thin and low contrast edges can be sharpened to produce an image emphasizing fine edges and patterns. Unlike “Neutral” and “Faithful”, “Fine Detail” is intended for images that will be used straight from the camera, without post-processing (however we suggest you to take RAW images to enjoy the maximum post-processing flexibility).

After looking at these color profiles in the video, I noticed that sharpness is different across color profiles. This was something I did not expect, i expected only color and saturation to be affected. So if doing an overhead sketch shot, you would want to increase the sharpness to catch the fine detail. Or this could be something you do in post processing. I am unsure how to do sharpness in post processing and how it will affect the quality of the videos, or if this is something you want to do as you film. It’s very different from shooting RAW photography and video.

I do think for the film look, you want softness and a flat color profile. This way you can color correct/color grade the footage after the fact. Then you can apply sharpness to only certain parts of the film. It’s also possible to load in custom color profiles which you can create yourself or others have created. This will give you additional effects. The other thing to notice is that different color profiles have different color settings that are outside of the stock sliders that come on the camera. So play with the color profiles and see if you can find a look you want for your shot.

When filming a video one of the common words you will hear is the word aperture. Most people care about aperture to get a very beautiful blurry background when shooting a subject. This blurry background is known as bokeh and it can either be good or bad. Typically the blurrier and creamier
it is when the background is out of focus, it’s called good bokeh. When setting up a shot, it’s part of the triangle of settings I keep mentioning. ISO, Shutter speed, and aperture. Aperture is a tricky setting, because it actually adjusts things in two ways. It changes the amount of light let into the sensor and the depth of field. Let’s talk about what happens when you adjust the aperture on your camera. When you open the aperture,
you are opening a diaphragm which lets more light into the sensor. You can picture a circle getting bigger the more you open the aperture. Opening the aperture is usually referred to as changing the f-stop (full stop). The lower the aperture (for example f1.8), the wider the opening is letting in more light. The higher the f-stop setting is, the smaller the opening, and it let’s in less light. So you might be asking why would I ever want to let in less light? Isn’t light KING?!?!

Well when you are adjusting the f-stop, you are also adjusting the depth of field. The lower the f-stop,the shorter distance of what is considered in focus. So at f1.8, the depth of field is considered shallow and only close objects will be in focus, and your background will be out of focus. This is how you produce good bokeh. If you raise your f-stop all the way to something like f/11, then things further away will be more in focus. If you wanted to capture your subject and clearly all the items in the background,
then this would be the setting that you want. The best way for me to describe it, is to picture an alligators mouth. If the mouth is barely open, the aperture is barely open, there’s barely any light getting in and the focal length is very far. If it opens up really wide, it lets alot of light in, and the focal length decreases. If this is hard to visualize, i’ll walk through some tests now showing how the aperture impacts your video.

Video Parameters:
Canon m50
f/2.0 to f/11
30 fps
1/30
iso 200 (800 at f/11)
15-45mm f/3.5 lens
22mm f/2.0 lens

Let’s go over what we saw from looking at the footage. As the f-stop was lower, we let more light in, and the focus was very shallow. I don’t know if you could tell, but with a shallow focus, it’s possible that someone’s
eyes can be in focus, but the ears or top of their head is not in focus. Sometimes this is what you want, depending on what shot you’re going for, but sometimes going too narrow isn’t what you want. Another thing you need to consider is all that light that’s being let in. If you were outside in the sun, f1.8 will usually blow out your image and overexpose it. This means you might have to crank your shutter speed very high to compensate, but if you are going for 2x the frame rate, this isn’t possible. You will have to find a way to make things darker by adding an ND filter (which i’ll cover in another video.) So just consider that when working at lower apertures. As I
increased the aperture towards f/11, you’ll notice it let in alot less light, and things in the background became more and more in focus. For a cooking show or maybe a group picture, I could easily see myself increase the aperture to make sure I don’t miss out on any details. However with less light being let in, i’ll most likely need to tweak the ISO which will inevitably add noise.

So to summarize again, aperture controls how much light is let in and the depth of field of a shot.If you are wanting to get that nice bokeh, then set your apeture on your shot, then accommodate the shutter, iso and lighting to accommodate the look you are going for. Getting this right takes practice, and setup, setting up this shot took me along time to get the look I was going for. Hopefully this was helpful and provided you with some insight onto how aperture works.
