hi everyone, I recently went to orlando and I decided to practice a bit "night photography" which's actually just taking regular pictures at night, but when I got home I noticed an annoying glare (or reflection?) in my photos. perhaps you guys know what I did wrong or whats wrong with either my cam or my lens. I was using a D7000 and a nikkor 35mm

Any thought?
 
Were you taking pics from inside something? A car, bus or room?

First one looks like a reflection from behind onto a window in front of you.
 
Do you have, or did you have a filter on the front of lens?
 
...and so does the second one.

I take it you were on a tour when these were taken?
 
I had a similar problem when using a cheap UV filter. I've since moved to using only Hoya Pro filters. They can be pricey but when you've paid all that money for a decent lens, why put a cheap bit of glass in front of it?!
 
That's got the look of a cheap filter problem. If so, take it off. Having an optically flat piece of glass over your lens is always going to cause reflections like this, no matter how well coated it is. Filters and night photography don't get on very well together.
 
I'd have thought the reflection would have a slight curve to it if it was reflecting off the front element? (Nikkor 35 1.8 has a convex front element)
I'm just wondering how the reflection would get to the opposite side of the image and reversed. How would the mechanics of it work, David?

Do these not look like they were shot out if a window with curved glass?
 
hey... thanks for replying! two things:

1- no, I wasn't behind any bus window or anything, they were taken outside

2- YES, I have indeed a cheap uv filter ($10) on my lens just for protection

what do you think would be better, get rid of the cheap filter and use none or get one of those expensive hoya filters?

thank you so much...
 
send them to me via email and I'll use photoshop to remove them if they're of importance :)
But take the advice above, were you on a coach when taking these photos?

thanks! but no, actually they were more for practice... not even my favorite ones of the trip, but I was worried about the reflections. and no, I wasn't... it was outside. I guess it was the filter I had on my lens that day ;/

Yep.

Optically, UV filters do nothing, as your camera's sensor filters will block UV anyway. If it's for protection... well.. use your lens cap :) Unless you're in a very harsh environment you don't need to protect your lens with anything.
 
ive seen UV filters give a greenish cast to your shots as well, as David says just get rid and keep it covered up.
A CPL filter is a good choice though (for the right conditions, ie water, reflections etc)
 
Condoms!



They offer 'protection' but itd be inconvenient to use them all the time.

UV or skylight filters for environments where the lens is at risk. Lens hood most of the time. Lens cap when you're not using the camera.

It's simply a risk assessment we don't wander round the world wearing crash helmets (or condoms)

Nice one, Phil.:clap:

You don't need filters really, unless you're trying to achieve something with them: ND, grads, polarisers etc

You are better off with a hood.

Bright lights reflect off the shiny sensor and then back again from the rear surface of the flat filter, appearing as a mirror image on the opposite side.
 
Many thanks.
