Cameraman Francesco Gola 1981 year be born in Italy, its own job is an engineer, the composition of a picture of work of coastal long exposure that its film is rigorous, boundless atmosphere, very tall person energy of life is had on 500PX.
I (point to Francesco Gola, similarly hereinafter) on all seminar that offer in Italy, I can make a small investigation. I let all attendant people when seminar ends, before attending class oneself most the 3 photography mistake that often makes is written in a piece of paper to hand in me. Accordingly, I decide from all collection in the material that come up, choose give 10 most the mistake that often makes in long photography exposing to the sun will undertake demonstrative.
Mistake one: Prevent shake systematic setting to be open condition
A few very lovely technologies can help us acquire keener image, and because airframe shakes a brought faintness,decrease, this kind of technology undertakes weak smooth memomotion in us when very useful. Although differ,the brand differs somewhat to the appellation of this one function, but their action however very much the same (Kang Hejia resembling the Buddhist nun can what they use watch for an opportunity is camera lens is prevented shake a technology, and what Suo Ni, Aolinbasi and guest must use is airframe prevent shake technical) . But in the final analysis, technology of this kind of damping can be in maintain a picture to pledge changeless circumstance falls, reduce speed of 4 archives shutter to undertake filming again.
Prevent shake a technology to use sensor to diagnose shake, and pass series of model of mobile camera lens or sensor itself will undertake compensating. If camera is in relatively stable tripod to go up,the problem is (if you are in,have a time exposure of course, your camera is certainly in the) on tripod, so produce quaky possibility very small. Probably you know this, but your camera does not know however, so even if did not move, this kind is prevented pass lens of mobile camera lens or shaking a system to also can try is sensor will undertake compensating to shaking, and this kind of circumstance was caused actually shake (ambiguous perhaps) is not to eliminate them. So, if your camera stays smooth and steadily on tripod, still let us prevent shake a function to put out!
Mistake 2: Forget use glance board rise beforehand
Camera is turned over in sheet in, the light can carry scene, be glanced next board in reflexing viewfinder. Should press of shutter flashy, glance so that make the light direct and projectile arrive on sensor,board meeting is packed up. This kind of floating conference causes the little vibration of airframe, bring about photograph faintness thereby.
Shake to avoid this to plant, you can activation glance board rise a function beforehand. After activation, in press first when shutter, glance board meeting is raised, and press when you the ability when shutter can undertake filming again. Fasten the interval that looks down upon this trifling a few seconds, it can let airframe avoid to shake! Of course if you are used, is to not have turn over camera, become me this proposal is gibberish!
Mistake 3: Because impoverished and did not use lens of gradual change filter
Fall in a few circumstances (light comparing is not very big place) , in using only, grey density lens can let you get wanted result. However, below a lot of circumstances, radial condition asks we are used in lens of grey gradual change will maintain exposure to balance. If you are using lens of filter of ND of mouth of a snail, you can think the only way of lens of use GND filter is later period PS probably, but you are wrong!
You can hold filter mirror completely with the hand and before be being put in camera lens. For the shutter speed that is as long as a few seconds to a time of exposure, your only question adjusts the filter lens in the hand correctly namely. And to be as long as photography of a few minutes, although your both hands is not so firm,be like huge rock, final result also is met satisfactory (if do not believe try) personally. Filter lens is worn or need of course, below the environment that uses many filter lens at the same time in need especially (perhaps become you when the hand is jerky) .
Mistake 4: Install aperture F/22 to lengthen time of exposure
Regulation is very simple: If you reduce aperture, you will gain longer time of exposure.
Drive regularly in this below, you think can innocently to be moved merely probably move finger to adjust aperture to F/22 from F/11, can lengthen time of exposure to dichotomy bell from 30 seconds. Theoretic tell, this does not have a fault. But unfortunate is to phenomenon of a kind of physics is called optical diffraction, be less than F/16 when aperture namely when, the acutance of image will be reduced considerably. If you had used F/11 and the shutter rate with slower longing, reduce ISO or be using lens of the filter that decrease light will be better choice.
Mistake 5: Forget adjust speed
Speed is long when exposing to the sun help strength greatly, sometimes you may forget to undertake adjust and takinged care of aperture and filter lens only to speed. Remember every camera has limits of a speed, in its output inside this limits quality is identical almost. In advanced watch for an opportunity, this limits is ISO 50 normally to ISO 200. This means you to adjust those who have two grade the space, and the time of exposure that growing the two archives in photography exposing to the sun to mean a few minutes.
Mistake 6: Film like be used in atelier
Be in comfortable room when you or be when undertaking filming in atelier, without the outside the element can affect your picture quality. But if you stand erect is on the rock of the seaside, facing gallant maritime storm, how long does your filter lens meet have more than is needed complete " wet body " . Did not forget to li of mount is being wrapped to brush lens cloth neatly together before before leaving, want to know filter lens even if touchs the least water, can cause very tall diffractive appearance, let a photograph destroy thereby at once. Do not underestimate the force of nature forever, even if is clear sky 10 thousand lis, change of weather also is the kongfu of a tea nevertheless.
Mistake 7: Choose inferior filter lens
Augment mirror of a filter before camera lens every time, the integral quality of our optics system can be not had can avoid the ground to be reduced. Really, the filter lens trademark with a few well-known far and near is very costly, but are you at ease really an a few filter looking glass to put before your camera lens? Not, absolutely not! Pay close attention to quality so: Pledge again to filter lens not weight! You do not need all type of collect neat ND and GND filter lens. Try to understand you most what often use is which filter lens, the ISO that remembers wanting to use you next and aperture will complement filter lens. Be sure to keep in mind finally, the filter lens of much high quality is very close actually civilian. Want to use good Internet.
Mistake 8: Underestimate the power of wind
When you expose to the sun into the president, your camera also can be come from the influence of external environment because of the exposure that is as long as several minutes, even if now and then wind of a few seconds of presence, can yield your fail in a great undertaking on the verge of success. Buy a stable tripod, had found a place for its appropriate next. If be necessary to hang additional heavy thing on tripod link up with, will increase the stability of tripod. Avoid to use the rod in tripod, the axis in rising will reduce the stability of tripod.
Mistake 9: Without the viewfinder on the lid
Good not easy exposure 3 minutes, when previewing, discover the photograph was full of strange violet edge and halation however. Is this why? Although camera wants to let be entered through camera lens solely only, but unfortunate is the picture that still other and potential by way of can harm you. And the famousest in them is viewfinder. Enter from here to prevent the light, be opposite anxious adscript hood it. If your camera does not have you to provide a cover, you can use black adhesive plaster, if do not have adhesive plaster unfortunately, so has chewed chewing gum also is excelled a little without. The most typical outcome that viewfinder causes into light is occurrence halation. Right, if you have,do not have turn over camera, so disregard me again please!
If you use system of tab filter lens, so another light leak way that exists possibly is the aperture between filter lens (this namely why a lot of cameraman like) of lens of snail mouth filter. Below this kind of circumstance, best means of settlement uses black tape namely. The expressional form with filter lens the most typical light leak is to appear violet edge.
Finally if you are used, is to move axial camera lens, or was to install camera lens to turn receive annulus, light leak problem can appear on camera lens probably. The best method that settles this kind of case uses scarf hood namely it.
Mistake 10: Manufacturer of credulous filter lens
When you work laboriously purchased a mirror of filter of 6 archives ND, and think it can give you the effect of 6 archives really innocently. Unfortunate is, you wrong. Have in me unripe year, I never have discovery to lens of a filter can keep absolutely and consistent with manufacturer conduct propaganda, of course this differentia different is very small normally, but even if the difference of half archives, also mean mistake of a few minutes in the time exposure.
To avoid these mistakes, can try following move:
Choose a room, open the lamp to close a window. (You need the place that a light stabilizes absolutely)
Wear good watch for a chance to film the photograph of a piece of room, until get a perfect histogram. Below the record all filming data (speed / aperture / shutter speed) .
Bring looking glass of mount ND filter, adjust airframe parameter to install next, make exposure and the photograph before consistent.
Taking ND filter lens to take a piece of picture
Hand-in-hand travel compares the histogram that watchs two pieces of photographs, if they are identical, the filter lens norms that explains filter lens manufacturer is tagged is accurate. If new histogram slants left, your filter lens wants tall; with respect to the norms that alleges than him conversely, if slant right, the real standards that shows filter lens the tagging under manufacturer.
If histogram cannot enough coincide, that films again with respect to change shutter speed a piece, will obtain with this can film with the lens that do not have filter the histogram of prospectus coincide.
After you discovered gratified filter lens, try to build oneself shutter speed conversion table. And another possible method is application software of PhotoPills of the installation on the smartphone in you, it can let you be below the circumstance of use filter lens, get correct shutter rate quickly.
10 mistakes need above to avoid when undertaking the time exposure photographs. (the article originates network, thank extremely, tort will cooperate to delete immediately)
