Question about Nikon N70 35mm SLR Camera

1 Answer

Photos are coming out foggy.

My nikon n70 works fine, but the pictures are coming out looking cloudy or foggy. Is there a chance of a light leak, or is it something that I could be doing wrong?

    I have a similar problem with a Nikon Pronea 6i which is very like your N70 except that it takes APS film (What's that?)

    Assuming you have eliminated the possibility of light leaking in
    through the film back then chances are your problem is the same as mine.

    I have traced my problem to light leaking in through the viewfinder and spilling onto the film "around the mirror".

    I find that if I fire off 2 or 3 shots in quick succession, only the first shot is noticeably affected by the leak.

    I think this shows that the effect of the leak builds up while the part
    of the film at the is in position at the focal plane waiting to be

    The longer I wait between shots the worse the leak appears to be and
    again I think this shows that the fogging takes time to build up.

    I traced the source of the problem as follows:

    1. Remove lens.

    2. Set camera to Manual and BULB

    press and HOLD the shutter so that the mirror locks up

    3. Shine a high intensity LED torch in at the view finder

    4. Look into the camera body.

    5. Turn the torch ON and OFF a few times.

    If your problem is the same as mine you will see small pin-***** size
    rays of light appearing around the mirror as it sits in the locked up
    position. Sitting in a darkened room will help here but will also raise
    some comments from your partner or strange looks from your cat.

    My reasoning is, if the light leaks around the mirror when locked up
    then the chances are it will also leak while the mirror is covering the
    film in the normal position.

    Sorry I don't have a fix for this. I only finished 'diagnosing' the problem last night.

    I think paying to have the N70 repaired would be worthwhile as it is a
    very good camera. I'm not sure yet if I will pay good money to have the
    pronea repaired.

    If you want to do it yourself then Jon Goodman has some very good
    information and products for repairing light seals on older cameras at:

    Maybe there will be enough information there to get you going.

    Good luck.

It could be. One way to attempt to find out would be to take a picture with the lens cap on. You'll have to go to Manual mode and take a guess as to the exposure. I would also investigate the possibility of a dirty lens. If you have another lens, try that and see what the pictures look like.

I assume you're not using expired film, nor subjecting the film to extreme heat or humidity.

I have a sonny rear proction tv its very foggy the piture

Three things you need to do:

1) Take the back cover off and clean the:
a) Mirror with glass cleaner
b) The dust that collected on top of the CRT lenses

2) With tv unplugged, use a flashlight and look down the lense of the blue, green CRTs. There is fluid in there. If the fluid is not clear, then it needs to be replaced and the tv re-aligned. Not recommended for anyone without experience.

Cloudy fluid is typically indicated by a foggy picture. THis is assuming you have a standard 3 CRT rear projection TV.

Pictures are very foggy even on lcd screen

It is possible that your CCD is damaged and could have resulted from high exposure to very high intensity light or sunlight. This has resulted in imager having very poor resolution and so a very foggy picture. The best option is to approach or send the camera to the nearest Nikon serrvice centre- log on to find out with a search of the location- call the call centre and send the camera by post for an estimate before you can decide to go on. This is better that to open and run around for the spares. Hope you try and get help . Good day.

Image through nikon f80 dark and cloudy

I'm unfamiliar with the F80 but on models like the f65 and f75 the viewfinder screen has an lcd overlay and when the battery is exhausted or removed the viewfinder goes dark and blurry.

Looking at a picture of the f80 it looks like it's just an update on my f75 so it strongly suggests that you just need to insert a fresh battery. The lcd does draw power from the battery even with the camera turned off.

I hope that you found my answer useful, once you've tried another battery to confirm what I've suggested I'd appreciate it if you return the favour by rating my answer.

The problem is hard water and jet dry will not solve that. There is a new product out called The Dishwasher Filtration System. It filters the water going into your dishwasher leaving your dishes spot free with every load. It is very affordable and fits right under the sink. You will be amazed how sparkling your dishes look just after one load. You will love this product. Get it at

Phillips Magnavox 60 inch Projection Tv

That model is famous for having bacterial contamination in the CRT coolant causeing halos, and dim pictures with bad overall color issues. You can look into the lens of the CRTs when the set is laying and if the coolant looks cloudy or has any growth there you will notice it right away, and changing the coolant will restore color, clarity and brightness.

Mitsubishi VS-50703 Picture Foggy

Open up the back and look for coolant leaks in the CRT's. If you are curious as to what it is, it's the same type of stuff they use to make antifreeze. If you see something wet, it should feel slippery if you get it on your fingers and rub them together.
