Frage von alexanderdergrosse:
Hi Folks, I have questions about Graufilter.
(short and short)
I want a Nd / gray filter on / with the Hv30 use:
- What factor? what brand okay? Hama is okay?
Antwort von TheBubble:
How much light should remove the filter depends on where lighting conditions and camera settings you want to film.
Antwort von Debonnaire:
Depends of the amount of light from which you want to get rid of. Pro trim level of the filter wegschluckt, this means a halving of the amount of light which then falls onto the sensor.
Hoya would choose, but is synonymous Hama.
Antwort von alexanderdergrosse:
In normal daylight - that is real light and daylight lamps!
Good ausbeleuchtete scenes (light bulbs), outside (real light).
Antwort von Debonnaire:
In normal daylight - that is real light and daylight lamps!
Good ausbeleuchtete scenes (light bulbs), outside (real light). Yes, please? Because something is hidden there, somebody answer could / should / would like, or are simply very little insightful statements?
What do you really know?
Antwort von TheBubble:
How dark the filter must be depends on the lighting conditions and to achieve what you want to. Very bright light auszuleuchten and then again with a filter to reduce IMO is not really useful.
With the filter in bright light to the next open aperture or exposure time may be extended (of course synonymous a combination of both) without Überzubelichten. How dark the filter must be depends of the individual situation.
Antwort von alexanderdergrosse:
What do you really know? Sorry, it was too short of me ;-)
I want with the Graufilter more depth blur in the images received.
The filter, there are many possible explanations, I want those with good
I can win more s.TiefenUnschärfe.
Myself earlier with a Panasonic worked with a ND filter had dazuschaltbaren (electronic), but I am on the Hv30
changed, for better Ausflösung in HDV want here
before the lens has a filter, this time real.
Have now polarizer, UVfilter and Strenfilter of maxphoto.
Antwort von Bernd E.:
The filter ... there are many possible explanations, I want good ... Make sure you have a "mehrschichtvergüteten" taking his text, at least not inside is silver (both is important wg. Unwanted reflections). For strength is already a lot has been said, but for the beginning would probably be a very good, the three trim levels swallows - the filter can be synonymous with "0.9" or "8x" delineated.
Antwort von alexanderdergrosse:
Are there any more sets with ND filter, you can suggest to me that almost every situation the right hab?
Antwort von domain:
What do you need for any additional Graufilter?
For consumer cameras, as with the HV30 is a car einschwenkbares Verlaufsgraufilter about to trim level already exists. Everything to trim level is in the final picture will s.Sensor completely mixed and dissolved displayed, so why not and it may be synonymous a gradient filter, ie, a glass disc that one of the other increasingly dense "colored" is.
In addition to running the filter is of course not synonymous dust (or even larger chunks) on the lenses before and after the sharp Aperture and the Aperture displayed itself can be synonymous, the strangest form, for example, vertical slot like cats eyes at cheap camcorders.
In the video section is without Graufilter times not at all. Shutter speed and aperture must be placed in such a tight limits that all lighting situations, no other can be handled.
In short, I would be interested to know what you still need additional Graufilter?
Antwort von alexanderdergrosse:
Why ... Better pictures, and wants to better reach the depth blur.
Antwort von domain:
In the HV30, you can but the Aperture manual settings, does not it?
In the normal exposure mode, the camera then pans to open Aperture Graufilter first times the maximum, so that the exposure times are not too short. This should actually mE sufficient for your purposes.
But as early as possible that with additional Graufilter still can achieve an increase.
Antwort von shipoffools:
In the HV30, you can but the Aperture manual settings, does not it?
... In the HV30, you can while the aperture and the manual shutter control, but unfortunately not together, so if you, for example, the manual exposure time to 1 / 50 want to keep, you have no control over the aperture, because then the aperture automatic picks . You can then still in the manual exposure setting, which is logically synonymous influence Gain and Aperture, but a certain desired aperture value so you can not really reach synonymous. Hence the idea of the aperture in bright light from an external Grau-/ND filter for the large depth of field to get not bad times. This really is' not worth consideration.

Antwort von domain:
The completely separate rules of Aperture and Time is always on professional cameras, but then must stop synonymous to Graufilter manual eingeschwenkt be.
In very bright light, I could have a positive effect of an additional Graufilters already imagine would only be honest to me with a camera Consumer far too cumbersome, each time decisions and herumschrauben to have, especially since such a right depth blur anyway only with Tripod and Tele is reachable.
I can not remember s.Profis, the times of additional Graufiltern were reported, mostly from the internal range and much weaker are the filter of Consumer Cameras probably are not synonymous.
As they say, Jedem Tierchen sein Pläsierchen.
But please always remember: synonymous consumer camcorders do not work with Aperture and only time, but crucially synonymous with the third regulation, namely the internal Graufilter.

... That's the price for a "cheap" camcorder. It has a larger effort by professional results. But when the "effort" is worth ... why not? And a tripod is the duty HV30 anyway, this is not a Henkelmann and has no shoulder camera.
...

For a professional camera is the ND filter, so manual alignment. In the HV30, it is auto regulated, so no external control. Therefore I have an additional ND filter, I think make sense.
Antwort von domain:
If yes shippofools ok, but it seems to me that you maybe the automatic Consumercamcordern of yet not quite worthy to know. This is basically trying in most cases, pretty much most of that light from a situation out of which a professional manual synonymous would cease.
The priorities are:
1. Aperture preferably not much over 5.6
2. Exposure time possible, not over 1 / 100
3. these two objectives can often only be achieved with Graufiltern.
Professional cameras usually have pretty miserable Automatikmodi, but basically make their user manual to 90% (times of extreme situations apart) synonymous nothing more sophisticated than the automatics of Consumer Cameras imitate, or better said, the Consumer Cameras emulate, is what pros always already set.
Antwort von alexanderdergrosse:
When HDV Cam hv30, I want little help
with filter, etc., that the quality is even better.
Because I can sleep peacefully, if not synonymous
Professional setting options are (manual).
I am concerned with primarily Technical Quality,
possible that the pictures look good,
because the filter is crucial to help with.
Antwort von domain:
Sorry Alexander, but you are an illusionist.
However, if you clear results eventually could show, then it would be really interested me.
Can they look at a comparative frame analysis provide here.
Antwort von WoWu:
@ Alexander ...
... given domain, I can only agree ..... First, each filter change (and each piece of broken glass) that you are in the optical beam path insert a previously optimized procedure.
They change all the optical elements in the beam path are inserted, the sharpness of behavior, or the sharpness level and depending on the thickness of the filter may be synonymous to come vignetting.
Secondly läufts you with additional ND filter may be in the UV / IR case, because the built-blocking filter is not "sharp" enough filter.
The camera controls so by the non-visible light spectrum.
Your Picture becomes "sluggish". About Such radiation is synonymous with the color spectrum and to blurring the picture, because in the infrared is not identical with other wavelengths focus is mapped.
Even the White balance offers no counter-measure, because it is a shift or spreading of the spectrum is.
The issues raised in the area weitwinkligen further.
With such a compensation of light by the ND filter is a very experienced cameraman deliberately and carefully.
In the calculation of ND's do you use the following formula:
(Extension factor (in f-stops) = density / 0.3)
A density of 0.3 corresponds to a slowdown in half of the light, so a trim level.
Bernd has it already for 3 stops mentioned.
But it is quite possible synonymous several ND filter at the same time be used.
It is the rule that losses multiply Aperture: ND 0.6 2x combined with ND 1.2 4x gives Sun 8 stops.
If your built-in ND filter, now also "strikes" you have it with a cascading, ie a multiplication to be done ... and if the handling of the automatic, which can quite quickly become 'Aufschaukeln lead.
So great caution. ND always sounds so harmless ... but it is not.
Antwort von Axel:
The most effective approach to your camcorder with a small chip with the creative depth of field, is the distance between foreground and background to spread. Precisely because that is one million pixels on a small area drängeln, hast thou with the HV30 DOF in terms of a more favorable ratio of pixel size and dispersion circles.
The condition is that you hold open the Aperture (correctly), but mainly just a large relative distance between the subject and background to produce. Relatively, because close-ups as you realize, a few centimeters to rich. The third factor is the focal.
When shooting in the sun, if the ND filter built anyway Connect, affects a very different phenomenon, the quality of the images: Um, put simply, the "earth" to expose correctly, the automatic in Purchase, that the "sky "(or anything synonymous Bright, which is directly illuminated) = overexposed zeichnungslos is white. These recordings were far more by a ND-filter gain than small DOF.

Thank you, friends, I'm doing tests!
