Getting a new camera it takes some time to find out what works and what doesn't. I've watched so many videos shot with the AF100/101 that looks unexciting, flat, blown highlights, chroma clipping, bad skintones and some even noisy. So does this make the AF101 a bad camera?
I know many had their hopes set very high since this one was suppose to be the DSLR and DOF adapter killer. When you have high expectations you're bound to be disappointed. Many of us, me included, have made some really nice looking videos with both the 7D and 5DmkII despite all of their shortcomings and artefacts. Why do they often look great and the AF101 not?
I've narrowed it down to these facts about what makes a good looking image or if you prefer a "cinematic" image:
Soft, warm look, crushed black, soft highlight clipping, shallow DOF, rich colours without bleeding or clipping and warm skintones. All of these things are trademarks of a DSLR. Then you have two things you create with proper lighting and that's to avoid a flat looking image, mostly to do with having the background breaking any flatness. The second being creating a dynamic looking image with selective focus and contrast. Sounds simple right? So why aren't all of the AF101 images like this?
When I have a 7D or 5DmkII on set I use my Marshall 7" monitor to judge exposure. False colours is a great invention and it makes it so easy. Just stay out of red and you are safe. Avoid to much dark blue on people and you are safe. Choose the colour temperature and you get the right skin tones or mood. If you try to follow these simple rules on a AF101 it might work and it might not work. There are a couple of things that doesn't work like DSLR shooting.
You must be extremely careful when selecting colour temperature. Having white anything other than spot on and exposure higher than 85% will make yellow/orange to clip. It's one ugly clipping so you must avoid it no matter what. Blue, red and green are not as sensitive but watch out for yellow and orange. Under daylight balanced bulbs clipping is not bad. It clips but really nothing ugly about it. It's under tungsten one can run into problems. One way to make it work is to lower the colour temperature in camera and make it warmer in post. Then you can get rid of much of the ugly yellow/orange clipping and halo. Under mixed lights it can be difficult to balance the camera. I did a short video under a mixture of streetlights and it was really a trial and error in each shot to make it look good. But I could so it's not impossible.
A shallow DOF can really help to make clipping much more pleasing by making it smooth. So even if the camera itself don't have a perfect handling of colours the user can make it look good.
Exposure works the opposite if you compare with a DSLR. I seldom have any problem with highlight clipping on either 7D or 5D. It clips and looks pretty smooth. But blacks are always crushed on these cameras. I don't think it's a bad thing since it does get rid of noise and makes the image looking contrasty. The AF101 is just the other way around. You have plenty of detail in shadow areas which is great and not so great. By itself it looks way flatter than the crushed black of a DSLR. This is not a problem, lower black level to crushed and you have the same contrasty image but rather than being a "feature" of the camera you now can choose to crush it.
As long as you are spot on with white, highlight clipping is okay. Not as smooth as a DSLR but still okay. Get it slightly off and all sorts of ugly colours starts to creep into the clipping. I really can't stress white balancing enough! If you look upon a DSLR working in the upper spectrum up to 100% white I would rate the AF101 to work in the lower end at 85% white. I also think white looks best when it's off white as compared to super bright white. This is also one thing that sets a "cinematic" image apart from a "video" image. White is seldom pure white in a block buster.
Updated 12 February: It seams the chroma channel on the AF101 is prone to clipping using the default Chroma level at 0. Reducing this and choosing a flatter gamma curve like HD norm or like the flattest Cine D does make it possible to have higher exposure without chroma clipping. The default setting is very saturated so having this below -5 helps alot. It's not a real fault in the camera just the high level of chroma coming from this camera. Reduce and be pleased.
On a DSLR you are limited to a small number of settings, sharpness, contrast, colour and colour temperature. On the AF101 you have many settings to tweak the camera. You can create one setting that will be a middleground setting that works pretty good in all situations or more likely, create several to suit different kind of shots.
You can get this camera to look bitingly sharp or very noisefree. It's really up to you and it makes this camera very versatile. My goal is to make this camera look as good as possible and really the tools are at my disposal. Looking at what some of these settings do this is a shortlist:
Detail: Makes the image more or less detailed. At 0 it's very sharp so to make it softer I would step down a couple of steps at least.
V Detail: It affects only vertical details so has less impact than detail.
Coring: This is noise reduction. Higher smooths noise and lower makes it more coarse.
Gamma: You can select different curves to tailor gamma. The flattest looking is Cinelike D and the most contrasty is Cinelike V.
Knee: Set where highlight roll-off starts. Low starts earlier and high starts later. This is invalid when using Cinelike D or Cinelike V.
Matrix: Sets how colours and mostly noise is perceived. Cinelike is the most noisy and Norm2 is the least noisy. But it comes with a tradeoff since Norm2 smears the image and this can be seen in peoples faces sometimes. Fluo adds magenta to compensate for fluorescent lights and their green spike and Norm1 is a middle ground between Cinelike and Norm2.
Going back to the trademarks of a 7D or 5D that manage to mimic a 35mm camera very well - Soft, warm, crushed black, soft highlight clipping, shallow DOF, rich colours without bleeding or clipping and warm skintones. Okay let's start to tweak the camera.
Soft. I would step down on detail to between -4 and -7 to make it softer and more pleasing.
Warm look and crushed blacks. These goes hand in hand since you can colour correct with lowering gamma and achieving both a crushed black and warmer colours.
Soft highlight clipping. Get your white balance spot on and stay below 85%. Set lighting as smooth as you can.
Shallow DOF. This is one area where I think many are using to wide angles. Stay at longer focals, make the shoots tighter. Lenses makes all the difference with this camera since the sensor is smaller than an APS-C one that we are so used of seeing. Go for 50/1.4 and 85/1.4 whenever you can.
Rich colours without bleeding or clipping. Get your white balance right and never go above 85%! Lowering gamma makes the image richer.
Warm skintones. Now this can be achieved in many different ways. If you can I would set up a very soft 3.2K light as key for the face or making as neutral colour in camera as possible and colour correct in post. Set exposure for the face at max 60-70% or even lower to get a rich warm look.
These are the things I would do to make use of the AF101 to it's best. So far besides shooting many tests I've done one daylight cloudy video, one under 5600k light with deeper blacks and one at nighttime under mixed lights. I've also shoot interviews in mixed shade/sunlight and indoors under different light conditions.
Remember, in the end we do make videos that are an artistic presentation of the real or imaginary world. Not something that is exactly like the real world. But getting the camera to work within it's limits helps to give you something worthwhile.
