Hi /p/

I want to know what causes this overall white effect in long distance photos.

Thanks!

I took this pic, most of my pictures look like this. It was taken with a film nikon camera with probably some standard cheap lens. Just wondering.

Thanks.

Polarizing filter would help

Thats what I thought, thanks. It's not my camera, i borrowed my brother's 10 year old, and it was used when he got it, camera. Was thinking about getting into photography as i've noted I took about 4,000 pictures in the last 5 months with my canon sd800 is.

Looks like my assumption wasn't far off. Looks like my learning is not going to shit, at least so far.

That shows up at any distance, either whitish or light blue. It isn't your camera, it's physics, something about light refraction, I don't remember right now. Polarizer or uv filter can help, polarizer moreso.

The atmosphere.

You can fix a lot of it in postprocessing, I've found.

Not gonna ask you to hold my hands through it, but anywhere I can find out a good way to do so?

Play around with the "Levels" control.

its just haze, pretty much dust and pollution etc in the atmosphere blocking light over a long distance, like ppl said before a polarizer would help a little bit

levels (or curves...) is the first step. it helps if you load an alpha channel or just make a quick mask of a vertical gradient, to match the actual depth of scene.

you guys are awful
ITS CALLED A UV FILTER
"as you gain altitude, for example by going up a mountain, the amount of UV increases. Under these conditions a UV filter can prevent a blue cast in photographs." -photo.net
it'll also protect your lens glass.
do it, trust me.

Who doesn't have a UV filter?

If you don't already know this, it's essential that you buy a UV filter for every lens you have.

Cost of replacing a scratched UV filter: 15 bucks maybe?
Cost of replacing a lens: fuckload

The math is quite simple.

It gets beaten to death, but I'm replying anyway.

The math isn't so simple. If you use good lenses, you need to use good filters, otherwise what's the point of the good lens? I once figured the cost of outfitting a 70-200 f/2.8 lens with a quality multicoated filter, it was very expensive. I then called the manufacturer and found out how much it would cost to have the front element replaced, it was not much more than a good filter- about 20%. Given that in fifteen years as a photographer I have never seriously damaged a filter or front element of a lens, I decided it's worth the risk of slightly more expense to maintain the highest possible optical quality.

$15? A good once costs more like a hundred.

What the fuck kind of UV filter are you buying? 300 mm or some shit?

At that price it won't even be optical glass. You are retarded.

Cost of adding a filter where its not needed: decreased optical quality, increased flare.

Value of a great photograph: Priceless, but if you make enough of them you can get rich and famous.

Cost of a metal lens: $~5-~15

Advantages of a metal lens hood: Looks nice, cuts down on flare, virtually invincible.

That's a 77mm front. I'm looking on Adoramas site and they sell a single pure UV filter for more than 100.

I'm used to buying things for small lenses, both mine are 52mm. I'm sure I didn't pay over 30 for either of the filters.

What brand are you buying then?

I have a Quantaray and Hoya. Both are multicoated. I never have a problem with flare, but then again one lens is a 60mm and the other is 35mm.

The most you can spend on a 52mm filter from Adorama is for and IR/UV filter that costs 84 bucks.

You should be aiming for B+W filters or Hoya Pro ones at a minimum. Don't buy the cheap ones from anyone, even Hoya. Hoya's green filters are shit.
