I took my D4 out for a walk yesterday. Out of nowhere it started to rain heavily. Of course I did not have any cover or whatsoever with me. I walked about 20 minutes with it through the rain back to the car. I was not worried too much since I had used other Nikon DSLRs in heavy rain multiple times in the past and they never let me down. Back in the car I turned on the camera to check if everything is okay and the camera did turn on. I did not take a picture, I just checked the upper display. I let the camera dry over night. This morning I wanted to use the camera and she did not turn on. The upper display was indicating the battery was empty so I took out the battery to charge it. In this moment I realized, that the battery was a little bit wet. I immediately got a hairdryer to get possible moisture out of the battery compartment. A few hours later the battery was fully charged and I placed it back in the camera but the camera wont turn on. When I put in the battery the upper display shows an empty battery symbol. I also tested a second battery which wasnt in the rain with me yesterday. When I turn on the camera the green LED on the back lights up for a second as normal and also the backlight of the buttons and display work fine but I cant use the camera. Of course when nothing helps I will have to get the D4 to a dealer but maybe you have some suggestions for me. Please let me know. EDIT: I sent the camera to Nikon and they sent it back immediately without even opening it because they dont have replacement parts for it. However I wont give up on my D4. I cant accept to sell it as defective. I opened the body and just like I assumed there was corrosion on the power board:  I cleaned everything from all sides with alcohol but camera still doesnt turn on. Do you know a place/person where I can get a replacement for this board? I cant find anything on ebay. If I cant find anything I might get down to component level repair. Im pretty sure the rest of the camera is fine. I guess there is a tiny transistor or cap that might be blown.

I had an unfortunate accident where my DSLR camera (and me) briefly ended up in a river. The camera wasn't fully submerged but it did get very wet. It still works, sort of, although the electrics are doing some random things. I'm hoping that's just a bit of dampness doing that, that will fix itself when it dries out fully.  More concerning is that the documents exposure metering seems to be all wrong when using the viewfinder. Pictures are extremely overexposed and nearly white. But if I use live view, then they are fine.  Why could cause this? I assume the light is routed a different way when using the viewfinder and maybe it is going through something with water/condensation on it?

The LCD on my Nikon D3000 is displaying the following error message:     Error. Press shutter release button again.   I have pressed the shutter release button but the camera still does not work.

I'm far away from civilization thats why I need your help guys. My problem is: MacBook Pro 13" early 2015 is not turning on and charging and the trackpad is also dead.   Charger's LED does not shine by any light(red/orange/green) . But I tested my charger with another MacBook and charger is working. I tried to connect another charger. First 1-2 minute I can see green light and then LED turns off. Trackpad is not react to any action (like double click). Right now this is just some plastic area Turn off and turn on battery connector also didn't help me.   The laptop did not receive any damage and was not flooded with water. Day or two before I got it from safe and checked my email then closed it and put to the safe again(hotel standard safe) (everything was okay but I didn't remember battery charge percent at that day) then I open and figured out that MacBook is dead.

Why does a flash freeze a picture even if I use a shutter speed like 1/10 sec?  I don't understand it, because the light will hit the sensor the whole time, not just when the flash is fired.

I'm considering purchasing a DSLR for the first time here in the next couple of months. The two "big boys" seem to be Canon and Nikon. I've looked at both companies, and I can't really see significant differences between the two.  Are there any?  (Please don't go into a flame war here -- I'm looking for factual differences between the cameras, not "I enjoy X because of Y...")    Also see   for another important part of the story.

When I press the shutter release to focus, a message on the viewfinder displays F--.  Any photos snapped turn out black.   I switched the camera off, took out the battery and memory card and rested it a while, and then it was ok.  But again, after a few days, the error occurs again, and it seems it will keep happening.  What should I do?

Hello recently I went to best buy and played with a Nikon B500, it was great. I was able to focus on the smallest things, close or far, zoomed all the way in and all the way out. So I went on the internet and found out that the B700 shoots in raw so I got it instead thinking it was better. Only I cant get it to focus on anything close up, weather in macro or not after like 25% zoom it no longer focuses on anything no matter what settings I put it on leaving me to think that I should have gotten the cheaper B500. It may not shoot in raw but at least it would be usable. I am fairly new to photography I had a friend with much more experience come over and try to figure it out. He told me that my camera has a range that it is able to focus on. Only the cheaper B500 focused on things way more zoomed in and with the camera much closer to the object so it doesn't make much since to me. So my question is why wont my camera focus on macro shots (weather in macro or not)?

I have recently tried to take pictures of stars using my wife's D7000, but I couldn't get it to expose for more than 30 sec. In my old D70 I used the wired remote to do long exposures, but now I have only the wireless one. How can I get it to work?

I took some shots recently and I noticed that I'm getting a lot of little black dots in my images.  I cleaned my lens thoroughly with the Nikon camelhair brush and retook the pictures but once again, the dots appear.  I'm shooting with a Nikon D7000 and using a starter lens. I've attached an example (notice the black spots on the chairs, on the ceiling, etc).

I'd love some advice in repairing a water-damaged laptop.  My girlfriend spilled a glass of water on her Sony Vaio and now it doesn't turn on...at all...dead! What steps should I go through to work out where the problem is and which part(s) I'll need to replace?  I can't seem to find out what has happened by just looking at the circuit boards. I'm new to electronics but could buy relevant volt-meters etc. I'm just looking for a decent trouble-shooting guide.

I just bought Nikon 18 - 55 mm f/3.5 - 5.6G VR AF-P DX Nikkor from .  When I connected it to my Nikon D5100, the autofocus didn't work. There was nothing about this from the original seller's website.  Is there anything I can do short of returning?

I have a fairly new Nikon D7000 (I've taken about 2000 pictures).   Something happened during my last trip, where thew viewfinder never gets sharp anymore. It always looks out of focus, regardless if i am in manual or automatic mode.   Pictures still come out sharp, and when I switch to the LCD screen I can see the focus, but not in the viewfinder.   Is there some sort of tuning that needs to be done?

I know there have been a lot of posts on this topic, but I haven't found exactly what I am looking for.   I noticed some dust spots on my sensor for my D750 after I took a picture with some sky in it and then was playing around with "dehaze" in Lightroom. Okay no problem, I have owned the camera for a year probably time to clean the sensor.   So I do a bit of research online and land on the fact that I can do this myself. I also want to learn how so I don't need to spend $50 or $75 each time I need this done. I decide to buy .  What I do is close my aperture down to F22, put my ISO on 100 and then set my shutter speed to 2 seconds or so and take a picture of a well lit white piece of paper.   I then go into Lightroom and jack the dehaze and look for dust spots. I see a ton. Okay, so now let's clean it. I wet the swab with a few drops to get it just saturated on the top of the swab, apply some pressure, wipe left to right, turn it over, wipe right to left and done.   Then I took the same picture and although the dust spots are different, they are still there! What the heck? Okay maybe it just needs a good blow out. I took my  and blow out everything I can inside of there, then I do the same cleaning method as the first time, except this time I start with a dry swab, throw it out, then get a new swab, wet it and clean it again.  I take the picture again... and they are STILL THERE. Okay let's get out the high power flashlight. I wouldn't say I scrubbed it, but I went back and forth with the swab on what seemed to be a stubborn spot (I know, sketchy). Then I clean it again with a normal swab and take another picture.   This went on and on and I have basically ran out of swabs. I still see spots. I used the same swab a few times (I know, also sketchy) because I just couldn't figure out why it wasn't getting clean. I even tried a can of air (although some don't recommend that because they have solvent in them, but I was desperate and some people on youtube did it). That actually seemed to help, but in the end I still have spots.  So obviously a lot of you will tell me to just "take it in! you're going to break your sensor", but I really want to learn how to do this. And now I am just stubborn.  The spots are at the top and bottom of the frame mostly.  Any ideas? I ordered  today, and I was going to try it out very carefully. I also ordered .       EDIT: I tried the gel stick. It did seem to help, but on the second try something else got on the sensor so I am going to wait until tomorrow to get the swabs and then try to do a swab cleaning + the gel stick again... we will see.  EDIT2: Well it looks . I think the gel sticky stick helped but it's still not spotless. I ran over it one more time. I also included a photo above to the people are nervous about cleaning their own sensor. Obviously I can't guarantee you won't screw up, but I ran a swab over this sensor at least 15 times and it still shots great.

I have a most vexing problem.   I have a Nikon d5100 (roughly a year old) which up until two days ago handled exposure and metering just fine. However, at night, in a well lit room (florescent bulbs) in which I NEVER had problems capturing images at reasonable shutter speeds, apertures and ISOs (&lt; 400), here's what's happening now:   In Manual, even at low shutter speeds (1/90 and lower) and relatively open apertures (3.5) - ISO 640 and less - my pictures are almost completely black. Pointing the camera at a bright lightbulb just barely captures the light with heavy shadows all around it. Exposure compensation no longer has ANY effect on the exposure Shooting in Aperture Priority mode at f/3.5 at anything lower than ISO 1000 reduces my shutter speeds to 1/2 or lower to compensate.   Yes, I know. ISO. Keep in mind, the room is quite brightly lit and I never had this issue prior to last night. That being said, the only way I can capture a reasonably exposed picture here is at ISOs 6400 and above. But even a picture at 1/125, f/5.6, ISO 6400 (manual) is still ridiculously dark.  I have taken the following step to troubleshoot, to no avail:   Turned exposure compensation up to the max +5.0 - no effect Turned shutter speeds down to 1/40 and below - extremely limited effect Turned ISO up to 6400 and beyond - limited effect Update the camera's firmware (1.01 > 1.02) - no effect Reset the camera using the buttons with the two green dots - no effect, multiple tries Messed with the metering modes - no effect Turned it off and on again - no effect Stared pointedly at the camera - camera didn't even flinch   I am at an absolute loss here and I really, truly, need help.  Images:  ISO 100, f/3.8, 1/3   ISO 100, f/3.8, 1/90    ISO 1000, f/3.8, 1/90

A good friend of mine has a d5100, which was working perfectly fine yesterday. Today, however, it refuses to autofocus at all - it makes no effort to move the focusing ring etc.  I have tried everything I know, from the obvious (making sure it's set to auto, not manual focus), to the less obvious (changing AF-L settings, trying Live View), to the downright desperate (trying every mode, random setting, and a menu reset) among others. I have also tried changing lenses, but the problem is the same.  This points to the problem almost certainly being in the camera body. The lens contacts are clean, the lenses were correctly fitted and it was bright enough to autofocus.  Currently I have no ideas other than a faulty shutter release button, broken circuitry (unlikely), or some bizzare instant-burnout of the lenses' AF motors.  Please, does anybody know anything about this? Thanks in advance, I will be eternally grateful (and owe you a beer/wine/tea/soft beverage if we ever meet!).

So I just got this Nikon D3100 Camera.  And I am trying to take a picture using autofocus with the kit lens(18-55mm).    The system is in Auto mode, AF-A, single frame and the lens A-M switch is on "A",  VR is "ON".  When I press shutter half way down, focus confirmation light in lower left corner of viewfinder neither lit nor blinks(hear clicking). When I press the shutter all the way down, the shutter seems locked (hear clicking, but shutter not released).    The manual says the shutter will lock itself if it can't get focus. But the place is well lit and have distinct color and I can easily focus using my old Canon.    The camera works fine in manual focusing, but I can't get it to take picture under auto-focusing.  I wonder is there something wrong with the setting that I don't know or is that I got a lemon?  Thanks

I just got a new (to me) Nikon D70s to see if the DSLR world is right for me. My dad took this picture of me:    In the middle of the bottom there's a rather large semicircle of shadow. Is this caused by the built in flash? If so, how can I avoid it (if I keep using the flash). Interestingly enough, when I shoot portrait instead of landscape, the semicircle doesn't appear.
