Aperture and Shutter scenes in standard



Frage von haenjuin:
Juli 2008

Hello,

I actually come from the photography and have a question regarding Aperture and Shutter standard scenes:

In photography, it is so that I be when the sun shines much light, that I aperture 8 and a shutter speed 1 / 250 can use (at ISO 100) - or hold different values, the EV value of 8 and 1 / 250 correspond, for example Aperture 4 and 1 / 1000.

What is here now in the shooting, which would correspond, for example in the sunshine, what values we should take in order to properly exposed film to get (or what would the camera set on automatic if it would).

Is already determined by the frequently asked question, but I have found nothing about this ... maybe I look synonymous with the wrong search words ...

Is it synonymous not just try it ... when the weather ... :-(

Thanks and greetings
Marc



Antwort von tommyb:

In general, one always turns with a shutter of 1 / 50 and the exposure is via the Aperture regulated.

If you with professional lenses works, then it always Aperture 5.6 to be - here, an s.besten Lens.

And if it becomes too bright, it usually takes ND filter (either in the camera itself or in front of the Compendium Lens).

If you do not have ND filter are available, then just take the shutter. But has an impact on the moving! A shorter shutter (1 / 250) leads to higher Bewegnungsschärfe - in photography is not different.

As for the exposure and the values:
As long as screwing up the picture looks good, or 70% on the zebra skin.



Antwort von haenjuin:

Hello,

Thank you for your answer ... much of it I already know from the photography ... But what I really went:

It seems the film is not to be here in sunshine Aperture 8 and shutter 1 / 250 is used ... oder doch? So I really only wanted to know whether the film behaves exactly like the picture it does ... or just what exactly the values need to be set in the sunshine to a correct exposure to get (real values, ie aperture and shutter). ;-)

Thanks and greetings
Marc

Since it standardized sunshine synonymous with standardized values in the video does not exist, nobody can give you the right combination always betrayed. You will see your photos certainly not synonymous with all 1 / 250 Aperture and 8 record?
Forget for the first time during the exposure Shooting: It is - unlike in the photograph - not so freely varied without unsightly image effects. The method of tommyb is the most sensible way to really get exposed to videos.

Antwort von haenjuin:

Hello Bernd,

no, of course, I do not take all the pictures with Aperture 8 and 1 / 250 on .... But I know that I am in the sunshine Camera always so, that aperture and shutter speed 14EV result, so as I said, for example Aperture 4 at 1 / 1000 or Aperture 2 to 1 / 4000. I think this is physics and it is no way out.

I would just know (regardless of the various effects in the small / large aperture or a long / short shutter occur): Even with video cameras (synonymous here regardless of the model) but there must be values, which I can judge. .. because the sun and blue sky is blue sky and sun and it can not, I think, that I at once Aperture film cameras 4 at 1 / 100 and 8 at once Aperture 1 / 100 must be used - as I said, always provided that the quantity s.Licht remains the same ...

Or is it really so synonymous with video cameras, this rule applies - that is, 8 and Aperture Shutter 1 / 250 ... might be synonymous?

Greeting
Marc

Longer shutter meinst du 1 / 250 produced only in Formula 1 motion blur.



Antwort von Schleichmichel:

He meant "motion sharpness." Would gestolpert almost synonymous.

Maybe something we talk to each other, because what I mean is this: sunshine as a natural phenomenon is not just sunshine, but be of varying intensity - depending of time of day or geographic location, for example. Thus, at a shutter speed of 1/250s (was not at video as a standard to be recommended) once Aperture 5.6 is correct, then times 8 or synonymous 11, bringing the exposure value EV also change accordingly.

For the same amount of light is of course synonymous imaging camera for the same same, only the amount of light in a blue sky and sun is not always the same - see above. Moreover, adding another point: Just as with film cameras or different sensor sensitivities, it is synonymous with camcorders. Some are light and some lichtschwächer, which requires different aperture settings. All of that is your desire for a universally usable exposure opposite.

This rule applies for the above reasons, not in photography, but much less in the video section. As my own 30 years of experience in the photo mogul had before I first worked with a video camera, I needed something synonymous to me the other way of working to adapt, but you'll see: In practice, it is then but a lot easier than it may sound. As I said: Look s.dem of tommyb described approach, it works already.

Antwort von haenjuin:

Hello Bernd,

Thanks again for the answers, I think now is so slow to me clearly what you and the others think.

I guess I will need some time to rethink. But after more than ten years of photography, the old "rules" (or whatever you want to call it) will probably only be s.acta times (well, not quite, because I will be photographing still synonymous ;-)).

Thank you (synonymous s.alle other posters) and greeting
Marc



Antwort von Jan:

"If the sun is shining - nimm Aperture 8" - at that time was synonymous for beginners and beginners. A long time ago, it was not always possible to stop with the exposure meter rumzurennen, some models had not yet built or where you could not trust.

It takes you only have experience next, at what time & what Lens Aperture with any pictures exist.

Let's suppose you have a 50 mm Lens (Full) and use the Aperture 8th Do you want but the person is exempt, so a portrait. At 5 m distance from the person is the depth of 2.8 m to 23 m - for a portrait - dung. At the same distance, Optics in Aperture 2.8 is the range 3.9 m-6.5 m - sounds even better.

For video I make it exactly as described above, 1 / 50 notes (1 / 25 is not enough for liquid movement representation, much faster than 1 / 200 sec results in a choppy motion.

No open aperture (ie, often f1, 2 & f1, 6, or F 1.8, depending on the camera in wide angle), since there is rarely a lens has its maximum (vignetting and sharpness losses), but not synonymous to high, because many of the diffraction Consumer devices sf 8 completely collapse. An average is good, when you need Lowlight eh but often open aperture to fall back, except you can illuminate well.

To stop exposure compensation then Graufilter use if you have a beautiful semi with 2 device has built-filters. ND 2 we often need very good weather with sunshine.

Still image so that you can only compare with video.

@ Marc

If you come from the photograph, you bring it with all the conditions to know what inflection, an Airy disk, the wavelength of light, the size of image sensors, pixel pitch and an ND filter is.
The combination can calculate the optimum exposure.
For those, which is too laborious, I have in my book display a chart from which you can ersehen that depending on the pixel pitches in most currently marketed in the video cameras out of an Aperture have no other choice left, if sharp would like to create images. Manufacturer leave it for this reason are often no longer to the Aperture manual to choose, because they have auto alignment ND filter or regulate according to the shutter to avoid in bonsai-sensors is not directly involved in the diffraction to come.
Tommyb it has been beautifully described .... forget the Aperture in the consumer devices and to see that you're somehow with ND's in the field of supportive haelen Aperture ... and if you have a lot of light, to see that you're not in the IR / UV tappst fall.
Synonymous Forget the "Crop" by the depth .... with a 5mm lens you have virtually no depth.
If you all want to know very well ... see below.
Still a lot of fun switching to video .... nothing is so easily and it will probably come a time where you nachtrauerst photography.








Antwort von haenjuin:

Hello,

s.alle thank you again for the answers.

Of course I have in the field of photography has a lot of accumulated knowledge ... synonymous with that of the diffraction is in photography no different s.Aperture 11 or 13, with my camera diffraction blur added, nor next, there will always be grayed out worse.

But I'm just out of the photography used to set everything manual (other than the Focus), so I wanted to know which factors in addition it plays video.

Likewise, I know of course, ND filter, etc., but that I need in photography rather rare, because the 1 / 8000 of my Camera auszureizen need it quite as much light (even when Aperture 1.2 is enough) ... ;-)

I have the Canon HV20, if I understand correctly has been so synonymous ND filter is installed, depending on the amount of light used car ... this automatic bothered me and I wanted to see how this works or how I can possibly influence. Unfortunately, I can so synonymous with the HV20 is not fully manual exposure, as I have lived in photography'm ... s.all I must me getting used ... or just buy a better camera, where I completely manual intervention options.

Sorry, but the photography a (very) expensive hobby and I have first preference with the HV20 take - but I think it is already synonymous is a good camera (which I incidentally due to the many praise here in the forum have purchased! ).

Greeting
Marc



Antwort von WoWu:

@ Marc

To ensure you have purchased is not a bad camera, but the big difference here is that the video producer through its continuous efforts to reduce production costs, to increasingly smaller chips, while higher resolution is always gripping.
Problems arise, from which you do not know photography allowed.
Inevitably Manufacturer thus can no longer allow manual intervention because they have every opportunity to exploit themselves in order the images be kept reasonably bearable.
Such Einstellerfahrungen So will you in the video area did not make, unless you switch one day in the Pro-Sumer area in which some of the cameras again allow.
Still a lot of fun with the Camera ... and welcome to the forum.



Antwort von Jan:

I had of Full and Still Image talk in the small video sensors is the case even harder. The depth or synonymous depth values for a 5 cm lens would have to agree in Full.

I just wanted to announce that the Aperture Case 8 experienced photographers brings nothing.

Antwort von WoWu:

I can well understand, but the transition of Still image video will photograph people but many times bad regurgitation, because with Still Image in every respect relatively to the fullest and it could draw in the consumer video technology with relatively "mere" offer to do have s.allen the corners and edges with a compromise situation.
All the more surprising, I find it really always that some really are trying to 5mm in the lenses (and there are really only 5 mm Focal), with depth of field to work.
When pixel pitches down to 2¼ kommst Du not even in the non-diffracted field, even if your blend is completely open.
If no compromises are ...
