Tageslichtfilter: Dichroitisch oder Lee CTB-Folie ?

Daylight filters: Dichroic CTB or Lee film?



Frage von KrischanDO:
November 2008

Hello,

'm currently in the process, a bit of accessories for my new Arri 650 Junior compiled.
Does it make sense to Arri daylight filter (around 140 ¬), or CTB full range of Lee - Slides in the filter holder. Not for the 5 x 10 hours studio use, but rather 3 x 4 hours per week.

Regards
Christian



Antwort von Axel:

I would only use natural light filters in order to produce light mixing, not to prevent it. Do you have daylight, which invades through the windows, it is better to filter through this film at 3200K warm and the desired color through the white balance to make. If I just look out the window, the light color more likely to be at 8000-9000K, and 5600K with the mixed results are still an ugly trick.

Do you have only artificial light, the WB also works better to create a situation to simulate daylight.

Only scattered glass filters are the filters of questionable value, since you do not last through the distance nor the dispersion can be dosed. So clearly, the better for 140 ¬, but it is more expensive than the synonymous for 5 ¬.

Now art thou but the luxury of Baustrahler people.



Antwort von Jürgen F.:

Hello Christian,
Take the slides, but not in the filter holder but with clothespins (wooden) s.den fortified gates.
The glass filters are pigs hot, and if you are short on artificial redenominate want, you will have problems the hot glass filter from the verrigelten slot herauszufingern. The only important thing is that the protective glass plate is always before.
For the price of 140, - ¬ würd ich lieber ne collection of filter screens, 50x50cm (gibts synonymous ready geschniitten) order.
Regards, Jürgen F.





Antwort von KrischanDO:

Hello Axel, Hi Jürgen,

thanks for the tips!

Baustrahler: No, which I use only when photographing jewelry, when I make a large-area light diffuser must be given.
In the video, I skipped and me two PAR 64 Reflector Flood 500s and two 300 short PAR 56 Flood pressed glass gegönnt. The first rotary-paid (equal to the first synonymous with the EX-1) I then zurechtimprovisiert to heavily bundled with these parts halfway klarzukommen. Once, after some fine-tuning the editing, the client was really happy, I have a heart and take the credit card, and 2 x 650 W, 1 x 300 W Arri Junior and ordered a case to petrol.

Small Lehrneffekt s.Rande: One should not 500s burner in 650er Arris stuck. In the spot-light position is not uniform.

Today I have in the rendering breaks, so a colorful 10-film set in the filter holder geschnippelt times and then put in the 650er.
The smoke detector is not started, but the films were not good.
So buy it arches and wooden clothespins ...
What can we then ever in the filter holder of Arris stuck inside?
The ND 3 Filters have until now kept.

Daylight or artificial light:
Tendeziell I will be in workshop rooms or small halls turn.
There, the skylights and windows with CTO film abzuhängen. dürte difficult.
Or there are little shoots on the Werkstatthof etc.
Inside, I will then either with more obvious and artificial light to make the WA. The blue background like I have - had perhaps too much Annie Leibovitz - photos viewed.
Or I will Arris with CTB blued slide. Daylight Arris are outside the budget.

Sincerely,
Christian

(Dinner is now ...)



Antwort von PowerMac:

Remember that you are best if the white point to change. Your light still remains from the spectrum artificial light, which a large part of the spectrum was cut off. For one, the technical quality of this "daylight" (which it is not) modest, on the other hand offer you the energy and halbierst light output.



Antwort von Valentino:

So I would just use the foil and CTO at 1 sqm (yes is synonymous smaller) under tension and then on a C-stand in front of the headlights are. The films will do the better because then they will not be charged.
What are Kunstliche has quite PowerMac, with five HMI lights usually never have the same color. When the burners are Klühlicht very änhlich most of the color temperature.
Especially in the video can look very ugly when the HMI is not coordinated.
A homogeneous light but I do not always umbedingt with CTB or CTO slides out, but must be classified as synonymous observe whether the light through trees druchscheint and thus gets Grünsticht.
On the other hand, I can tackle me by the Schwerfer with a 1 / 8 green filter and then in the post-production the green pull down slightly.
If I did not do this, would the green when you try to pull down the light of HMIs slip into magenta.
