Good Evening!
00:02.1
00:04.8
For this video, i had to wait for complete darkness outside
00:04.9
00:09.7
as for this video, i need completely artificial lights
00:09.8
00:14.6
to adress the second topic of critic me
00:14.7
00:19.5
which was lights and camera.
00:19.6
00:26.5
I did find it interesting, that critic me admitted, my lights weren't really good
00:26.6
00:33.5
because who ever have seen this can't really claim
00:33.6
00:37.3
"Okay, that is doing allright. Your lights are great, everything is fine!"
00:37.4
00:41.5
No. My lights aren't great.
00:41.6
00:48.0
You see a seemingly slightly blurry image
00:48.1
00:54.2
This is caused by a glaring light source that seems bright
00:54.3
00:56.5
but actually isn't enough for this webcam.
01:00.0
01:04.3
Let me show you some thing.
01:05.5
01:08.0
Right...
01:08.1
01:15.1
What you see right now are default settings.
01:15.2
01:20.3
This is what the webcam makes out of what its "seeing".
01:20.4
01:26.1
Its complete automation - let me set the white ballance to automatic as well.
01:26.2
01:31.3
This is what the webcam does by itself.
01:31.4
01:35.7
It has - uh, still - a slight blurr to it
01:35.8
01:41.2
because the webcam simply cannot make anything better out of it.
01:45.8
01:55.1
On top of that - if you take a look at the ceiling - it now has a strong visible noise to it.
01:55.2
01:59.8
This noise is caused by not enough light being present in this room.
01:59.9
02:08.9
What the webcam does like this is to counteract the low light by adding artificial amplification to the light
02:09.0
02:21.1
This also causes especially the left of my face to be almost blown out by too much light.
02:21.2
02:25.0
It's even worse with the T-Shirt i am wearing.
02:25.1
02:29.4
It's - for the most part - completely lost in brightness.
02:30.0
02:35.4
So what can we do about it? Lets try changing the settings manually.
02:35.5
02:42.9
I started by disabling the automatic white balance, removing the "default" autocorrection.
02:43.0
02:47.8
I replaced it with a setting that i know to be roughly correct.
02:50.2
02:56.0
This is the result. Yea, i think that's about right.
02:56.1
03:01.7
The tone of my face's skin looks halfway healthy i guess.
03:01.8
03:08.2
The background has a greenish tint to it on screen, but honestly, thats exactly what my room looks like.
03:10.6
03:16.5
This should give you a good impression of what to actually expect of this allegedly warm-white light.
03:16.6
03:26.2
Cameras will show you. Cameras will alway expose the inconsistency between the companies claims and what you will actually get.
03:26.3
03:31.4
The issue is the human eye, which is easily deceived.
03:31.5
03:34.3
But - oh well, I digress.
03:34.4
03:41.1
I'm disabling the automatic exposure. I'm disabling the low light compensation.
03:41.2
03:50.0
All of these settings. I changed the exposure to a manual setting of -5.
03:50.1
03:55.1
I am lowering the gain.
03:55.2
03:59.5
And you might have noticed: The camera tried to focus.
03:59.6
04:03.4
I'm disabling the auto focus feature.
04:03.5
04:09.0
What you can see right now is - in my oppinion - the best you can get out of this camera.
04:09.1
04:17.5
Let it be just a tiny bit of gain left in the settings, if you really need to (the artificial amplification)
04:17.6
04:24.9
But for the love of god, don't overdo it or you will end up with an unusably noisy image.
04:26.0
04:35.9
So what you can see right now is simply the best I could get out of the cam like this - using manual settings.
04:37.5
04:40.5
You can't get it any better.
04:40.6
04:47.4
I could now start any try setting the gain even lower, from -5 to -6.
04:47.5
04:54.4
But this would cause two things: 1) It gets darker. 2) As you can see, it flickers.
04:54.5
05:04.9
And now get this: If i raise the gain even further, the flicker gets really nasty!
05:07.8
05:18.5
The flicker you can see is visible, even tho I did sett the power line frequency correctly.
05:18.6
05:28.0
And changing this to 60 hz doesn't do it any better. It changes the frequency of the flicker a little, but it's still there.
05:30.0
05:41.9
As you can see, there is no changing this. And this flicker has to be unbearable for you so let me change this real quick.
05:42.0
05:45.4
It was only for demonstration anyways.
05:45.5
05:48.4
Right...
05:51.9
05:57.4
So this is simply the best to be expected out of this webcam
05:57.5
06:02.3
With this light - like i said - this is the best, this webcam can do.
06:05.6
06:15.3
You can also notice a certain blur on the image, which is caused by too little light.
06:15.4
06:25.4
Well... Yea, you've seen what I did. I tried tinkering with the settings already. That is all. You can't do better.
06:25.5
06:33.1
These are idealized settings. There is no way, you can do it better.
06:33.2
06:39.8
And this - for example - is just one reason for me to decide: I am interested in the Logitech Brio.
06:39.9
06:45.4
Yes, I do and I admit it! And let it be its 160 Euros.
06:45.5
06:51.1
Actually, i'd have to admit: It is interesting to me, BECAUSE it costs it's 160 Euros.
06:51.2
07:14.1
It was 250 Euros when it first launched. And to this i got to say: Sorry, but No. Just no. I'm a cam nerd, but: No!!
07:14.2
07:28.5
And that's because i've seen YT Videos of guys who actually have a DSLR and proper light, who tested this Cam against a DSLR.
07:28.6
07:40.6
So we're talking Brio VS DSLR Monster. And they compared the lower tier models as well, like the C922 and C920.
07:40.7
07:47.2
What can I say? The lower tier models got completely annihilated.
07:47.3
08:02.4
At too much light, They did exactly what I have shown you before: Everything becomes too bright too fast, the highlights get blown out, the highlights get lest in brightness.
08:05.8
08:11.8
The Brio was able to cope much better. It also was sharper image.
08:12.8
08:23.2
It also had a better contrast. The only thing it could not do and there will never be a webcam than can do it
08:23.9
08:27.5
- at least as long as they are built the way they are now -
08:30.8
08:44.4
you cannot blurr out the background. For that it needs a lot more light incidence, a stronger lense, a bigger sensor.
08:44.5
08:49.5
And this simply is not possible with a webcam.
08:49.6
08:56.7
But apart from this - like i said before - for that money, especially, if you consider what you still need.
08:56.8
09:03.0
You need the DSLR, you need a lens, you need some sort of mount, you need cables.
09:03.1
09:10.6
You probably need some sort of dongle to run the DSLR on a power adapter at a power outlet to not kill the battery.
09:10.7
09:18.3
As it will never survive a stream. You need a capture card to output to a PC.
09:18.4
09:23.6
That is... complete overkill.
09:23.7
09:33.2
You can't... No... for the kind of money you spend on that, its not worth it for anybody, who just does a live stream for fun every now and then.
09:33.3
09:38.1
Even if he is a tech nerd as me.
09:39.5
09:48.2
Because of that, i got to admit, the Cam (Brio) is interesting to me. But then again, its not *that* important
09:48.3
09:57.0
because - again - I believe, because i've seen how sharp the image of my cam can get on a day,
09:59.0
10:05.0
that i simply need good light - that is the most important to me right now.
10:05.1
10:11.3
I need brighter light and you did see it yourself:
10:14.1
10:22.0
Let me show you again - just a sec.... Here.
10:24.5
10:40.8
My current setup as is. I got one spot clamped to the microphone arm, the other one is leaned to the back of my keyboard.
10:40.9
10:44.8
I told you the reason: It's broken and im to stingy to get a new one.
10:50.3
11:09.4
With really good lights, really good LED lights, that have an effective diffusor on them, i could do about the same than with a soft box
11:09.5
11:22.8
I'd get soft light to get rid of those lines all over my face. Those are a there and.... right?
11:25.0
11:33.3
The thing is, those aren't half as bad on daylight, as daylight is much softer.
11:38.5
11:54.7
And Like I said, i need brighter lights, to run the cam at a lower exposure time without having to add gain to the image.
11:55.8
12:01.0
I need soft lights, i need daylight white lights.
12:01.1
12:05.8
(i got confused here tried to correct myself tho there was nothing to be corrected actually)
12:06.0
12:14.5
I've given you a demo on the differences, at least indirectly, when you were able to see, that in parts the image was way too orange.
12:14.6
12:30.8
That is, if i used manual settings. The issue is: Right now, i had to tune down the white balance quite a lot, so it gives me a halfway natural light.
12:30.9
12:40.5
Of course, as long as all lights were artificial, their white color doesn't matter as much, as you can always readjust them.
12:40.6
12:50.8
The thing is: These lights cannot be readjusted. This is what you get. Some sort of warm-white-ish light.
12:50.9
12:57.9
Of course, i could get myself daylight white bulbs for them, but do you know how expensive those are? I could never justify them.
12:58.0
13:04.9
Especially not, knowing the live span of those things. They break pointlessly fast!
13:05.0
13:10.9
And those companies wanted to tell me, they live longer than regular light bulbs?
13:17.3
13:27.1
Another issue is: At daytime, i'm getting daylight coming through the window right next to me.
13:28.4
13:33.2
Over there it gets dark. Let me show you:
13:34.9
13:39.3
If i place my cam like this....
13:41.8
13:45.5
(fumbling with a light) yea, thats about right...
13:46.6
13:53.7
You get the following effect you'd also see at daytime. From one side, light hits me
13:53.8
14:00.4
- this one right here - That would be the light coming from the outside.
14:00.7
14:07.6
Without additional light, the effect i'd get would be something like this exaggerated example.
