相機cmos沒你想的那麼脆弱 髒了就要清理

無論你如何切割它,攝影是一個非常昂貴的職業 你有沒有加上你整個攝影套裝的費用? 這不包括你過去用過的錢,你已經沒有了 無論如何,我們用攝影機花費了很少的錢 所以我們必須盡全力去延長攝影機的生命 我下個星期會在意大利的Dolomites舉行春季工作坊 我通常會去清潔攝影機 在我離開之前,我必須確保攝影機正常運作 在這部影片中,我會詳細介紹我進行攝影機清潔和準備攝影機的過程 我把這部影片分成四個部分 我會在下面的連結中提供,以防萬一你錯過了其中一個部分 那就是攝影機,攝影機,攝影機拍攝器,以及一些防禦措施 以避免未來的問題 我們來看看,關於清潔攝影機的問題 我最喜歡做的第一件事就是確保攝影機的機箱是乾淨的 不含污垢,在我清潔攝影機之前 因為我想確保沒有任何污垢,在我清潔之前會掉到攝影機上 我會拿一把導彈噴槍,把所有東西都噴到攝影機上 確保攝影機都乾淨,這些小的攝影機清潔筆也很不錯 我先把導彈噴槍拿走,把導彈噴到攝影機上 這是一個小的柔軟的刷子 這些攝影機清潔筆也很不錯,可以清潔攝影機的焦點和焦點 確保攝影機都乾淨 當你滿意後,你可以用毛巾清潔攝影機 當你滿意後,攝影機的整個身體都乾淨了 我會開始清潔攝影機的前面和後面 我會先清潔前面,主要是清潔前面 主要是清潔前面,要確保前面能夠清潔得很乾淨 你可以想像一下,如果你的攝影機上有一個小塊的沙 然後你開始清潔,你會把那塊沙刷到攝影機上 這會造成永續傷害,我們要避免這個 所以我會先清潔前面 我記得這攝影機價錢是多少,我會放在下面的連結 為什麼我喜歡這些攝影機,是因為我以前會用這些 我以前會用這些,我會用這些 我會用這些,我會用這些 這些只是軟的細膠布 但是我喜歡這些,尤其是旅行用的 因為你不需要再拿這些了 但是這些小小的小包裝 你打開它們,打開這個小包裝 我會用中間的 然後我就開始弄曲 從中間開始弄曲 然後就慢慢地向外 就像這樣,慢慢地 直到我去到攝影機的外邊邊緣 也不要做太多 就像這樣 又弄一圈 然後再弄一個圓形的線 And that usually will get the lens or the front element crystal, crystal clear right there And then the only real difference between the front element and the rear element is the rear element has contacts that you want to clean So pop it off, lift it upside down, spray, shoot the rocket blower all around here Hopefully any kind of debris will fall down Definitely want to get the outside area here and definitely want to blow out any kind of debris that is on these contacts Get that really good And then I take a microfiber cloth and I'll wipe those contacts really good Wipe along the edges right through here as well And then take another one of those ZEISS cleaning wipes and go through that same motion to clear the rear lens element I do want to mention, I don't, I very rarely clear, clean the rear lens element It's almost always the front From my experience, there's very little debris that really ever gets on the back But I do every once in a while, I will clean the rear But it's usually the front But that's the process that I go through when it comes to just cleaning the actual lenses itself Now as far as the camera body is concerned Cleaning sensors is definitely something that makes a lot of people nervous Used to make me very nervous, but I'm hoping here in just a few more moments, you will feel much more comfortable So first things first is to clean the exterior of the camera Same process as with the actual lens barrel You just want to make sure you blow everything off on the actual camera itself Through every single crevice and all the little dials and all the buttons below everywhere In the viewfinder, I like to flip up the flippy screen right through here Get underneath it and all those little kind of moving parts that enable a flippy screen to flip And just basically try and get it as clean as possible Wipe everything down Because ultimately just like with the camera lenses When you open up your camera sensor here or the cap You want to make sure that there isn't any kind of debris that could fall inside of it So getting the exterior of your camera body As clean as possible is definitely important Now as far as just kind of, you know, blowing off the sensor I should say that is what I do much more often I actually rarely clean the camera sensor And I'll tell you why in just a moment But to blow everything off, just open up the center cap here Of course, lift it upside down Take your rocket blower on an angle And just blow all the way around it like this And then any kind of debris will fall straight down Definitely want to blow off the little contact right through here But putting everything on an angle And of course keeping the camera body upside down Is very, very important Now as far as camera sensor cleaning is concerned The most important thing is to determine Whether or not you even need to do it And from my experience You don't need to do it nearly as often as you might think So a great little test to determine Whether or not you need to clean your camera sensor Is this right here So what I like to do, put a lens on your camera body Doesn't matter what lens it is Focus on something that is like a single color I like to use white I like to use my computer screen Mainly because you can make your computer screen much brighter So just find anything white like this And then you stop down your camera So if you're using like an APS-C or full-frame camera Stop it down to F22 I'm using a full-frame camera So I stop mine all the way down to F32 And I set the ISO as low as I can really So I always like to do at ISO 100 You can bump it up a little bit to 200 if you have to But I'm able to see sensor spots much better When the ISO is very low So stop down your aperture low ISO Set your focus on infinity So you want to switch your focus to manual mode Switch it to infinity And then go ahead The shutter speed really doesn't matter And then you just want to take a photo of your screen So what you do is this is the photo that I took Just looks like a white photo It doesn't look like there's anything there at all But if you come over here Inside of Lightroom And you click this little band-aid icon And you open this up You come down here And you select visualize spots And then you can drag this little slider All the way over to the right And all of the sensor spots will be revealed That is zoomed in all the way That's why it looks crazy like that But all those sensor spots will be revealed right there And you can see there are quite a few Let me just make this Let me fit this on my screen here There are quite a few And you can see the camera settings that I use One second exposure F32 ISO 100 And this is the photo that I came up with then So when I look at this right here This sensor really is not that dirty But I wanted to go ahead and clean it anyway It's been over a year since I've cleaned this camera sensor And it is a simple process And what made me feel so much more comfortable Is knowing that You're not actually cleaning the physical sensor itself There is a thin protective layer of glass In front of that camera sensor So you're really cleaning that glass You're not necessarily wiping the camera sensor When I realized that I was like Okay, you're kind of cleaning the window to the sensor So that kind of reduced a little bit of my anxiety associated with it But I bought some of these kits right here Buy them off Amazon They're pretty inexpensive The most important thing is You want to get the sensor swab size That matches your sensor So this is a medium format camera This is a medium format sensor size swab If you have full frame camera get a full frame size If you have APS-C size sensor Get the one for APS-C size Mainly the reason that's so important Is because you just want to be able to do one swipe You don't want to be swiping over and over and over again So this kit right here Comes with a bunch of these little swabs You open them up This is the swab that I used this morning And then you use the little sensor cleaning solution You definitely want to read the directions on your kit This one right here Had you drop just two little droplets One on the left side One on the right side And then you basically just very slowly Just take the sensor swabbing kit And then you just do a one stroke one direction And another stroke the other direction And that's it Want to apply a little bit of pressure You know these kind of You can see it kind of bending just a little bit I always like to see to where that There was just a little bit of bend But you definitely want to be careful Because most cameras today The camera sensors are stabilized In body image stabilization And you can damage those mechanisms If you're you know If you're putting the tension like this On your camera sensor There's probably too much But if there's just a little bit of curvature to it That's kind of how you know that you're applying Applying an appropriate amount I'll show you the after image here In just a moment Actually I'll show you right now So this is the after image So this is before There's definitely more here now Or before I should say And this is the after So before and after You know obviously there is still a few spots left But it did greatly reduce the amount of them The thing about this is You're never going to get it completely clean ever I've never done this before I wish I did But when you take a camera out of the box For the very first time I would like to go through this And see if that sensor is absolutely perfect I have a feeling it's not So it's natural to have a couple little spots on there So don't drive yourself crazy Trying to remove every single spot Because more than likely You will probably not be able to do that And at the end of the day You're not going to see most of these cameras These sensor spots anyway You know how often are you stopping Your camera all the way down And taking a photo of just a white object This doesn't happen too often You know every once in a while You might capture a photograph Where there's a bright blue sky And you might see a small sensor spot But if that happens to you It's super easy to remove that In whatever kind of post-processing software That you are using So now as far as tripods are concerned Tripods get super super gunked up and dirty Especially if you're photographing it Near any kind of seascape Sand is like the culprit But a lot of times If you open up the joints of your camera You can hear that kind of grinding Mine sounds a little grimy But tripods for the most part They all might be a little bit different But the general idea is pretty much the same Where you unscrew the legs completely Like this And then you just pull them apart Take off that little plastic thing I like to take an old toothbrush Definitely not my current toothbrush But an old one And just kind of brush in between all these grooves Rinse it out really well I like to take all of the tripod parts apart And put them inside of the shower And just kind of clean them off that way And then you just kind of assemble everything I would just definitely make sure That you are taking mental note As you are disassembling your tripod As to how you put it back together again It is pretty straightforward But if you're not paying attention You can get a little bit tripped up But the overall process is pretty simple And that's the number one thing that I do That's really the only thing that I do When it comes to just kind of Cleaning for my tripod If I'm photographing seascapes And I get hit by a wave And my entire tripod is covered with salt water As soon as I get back to my hotel room I will fully extend the tripod And put it in the shower And just let it run water on it for a few minutes Just to kind of get off as much of that salt water As I can because that is an absolute killer And then preventative measures So changing your lenses in the field Is definitely a hot topic I think that the overall consensus Is that most people do it A fairly similar way But I think everyone's got a slight little nuance to it And this is the process that I go through And I think it's been pretty successful for me So I'll have a lens in a bag And if that's the lens That I'm going to be putting on my camera body I'll make sure that the lens cap is loose So it's just all I have to do is just take it off And then I want to make a note To where the red badge is Because you know you line up the red badge With the red badge on your camera Put those two together And then you twist and then you're on On my camera and I think on most cameras That red little dot is somewhere Right at about 10 o'clock on a clock So I always want to make sure That I know exactly where the red dot is here Take it off put it right on And you're good to go I like that because it's one it's quicker And two the quicker you're able to do it That means the less time That your camera sensor is exposed to the elements So the quicker that you can do that Is definitely the better Now as far as tripods are concerned A preventative measure this is huge Is that and I see this all the time I used to do it constantly Is if you're photographing in water Whether it's the ocean or a river I would always unscrew the very first joint Extend it out and then put all of this underwater And that's the that's a recipe for disaster Because you're going to get so much Sand and gunk in these joints What I do now What I would definitely recommend Is to unscrew the bottom leg And extend that out and put this In the water right through here Because there's no joints through here Nothing there's no moving parts in this section So put this section under water Try and keep those joints above water That will definitely help you To not have to clean your tripod near as often Because when those joints get Really gunked up with sand They don't really lock down very well And your tripod legs can slip And then the last thing hot shoe covers So hot shoe covers I used to lose them constantly But there's a ton of electronic Things inside of these hot shoes And if you don't have a cover on it You're not using a flash or a microphone And it's completely exposed to the elements Even if it's not raining It could just be fog or mist Moisture can get into these electronic components And short out your camera I've seen it happen time and time again I lose these all the time Most people do I have a bunch that I bought off Amazon If I ever lose them I put one right back on So I want to keep those hot shoes Completely covered Because that is a point of failure on all cameras Is an exposed hot shoe So I definitely keep those covered If you have any questions About anything that I mentioned In this week's video Regarding caring for your camera gear Please leave those in the comment section below And
