Question For Taking Night Pictures.

Fri Dec 13, 2002 1:00 pm

Hi,

My question is: what can be done to that yellow shine when taking night pictures?
Or...is it just normal when you shoot with a longer shutterspeed?
Maybe a filter or so?

I uses a Olympus C2100UZ.

some examples:

it depends on the lighting. Most airports use those awful yellowish lights, but some, like YVR, use the really bright white type, I think they are mercury vapour lights. Anyways, the color tone of the picture should be dictated by the color of the light source.

So you think the yellow shine isn't disturbing the rest of the picture?

Thx,

Indeed some airports use mercury vapour lighting while others use sodium vapour and some still use fluorescent. You can buy a number of filters to remedy this problem, however these can be a pain. I suggest using Photoshop or whatever imaging program you prefer and correct it there.

Xenon,

You asked for help so I spent a moment in PS.



Converted the picture to CMYK

Went into curves

Pulled down the top end of the yellow to where the picture looked right.

Converted back to RGB

Resized it

One thing that you can do in camera so you don't lose dynamic range, set your white balance.
At worst, you screw up and die.

So the yellow on the tarmac is gone but so is the yellow from the plane...
You think A.net would accepted the picture like this?

Thx for helping,

Daniel

PS: What with that white balans

I notice your Olympus has the same problem as mine...it has that green dot in the same place on every picture. I clone them out with my photos though. Its visible in the lower right quadrant, somewhat close to the center.

White balance sets the colors tones for the lighting types, weather it's red tint of light bulbs or the slight blue tint of speedlights. As far as being accepted you lost alot of dynamic range by not setting your white balance in camera, so maybe not.
At worst, you screw up and die.

You need to change the white balance setting, and experiment with whatever the C-2100uz has (tungsten ??).

I used to own a C-2100uz but actually got rid of it because it wasn't able to take 'right-looking' night shots however ;,-(

"Converted the picture to CMYK"

Why would you want to do that and loose alot of colorinformation?
RGBs colorspace is ~16 million colors while CMYK is only a couple of thousand.
That means all colors not printable will be converted to printable ones once you choose CMYK, giving the image a faded, greyish look.

I would suggest keeping it in RGB and choose Adjust-->Selective Color.

Well, here's how I deal with that yellow-cast "problem":

1. First of all, you need to have a RAW capable camera to do this.

2. Take a picture with auto white balance/tungsten settings and the resulting image looks something like this (yuck  Sad):


3. Bring the RAW to somekind of a converter where you can set a custom white point.

4. Select a white point from the picture (usually planes body is good unless the plane is not white)

5. The resulting image should look somewhat nicer:

If you don't have a RAW capable camera then I suggest to try some color-correcting filters. 81A, 81B and 81C are good filters to start with...

I just played around with a shot which was similar to yours in tungsten colours.

Used ACDSEE auto balance and wallaa...

Love the texture the snow gives to the "sky" with the shining lights. Well done shot.

Janne...great shot and amazing the difference between the two shots...don't let Vasco see all this editing, like his World MD11 shot...all shots should represent the actual conditions so if the shot is ruined by horrid yellow lightsthen so be it and upload anyway Big grin

Jofa,

I send most of my stuff out to print so working in CMYK is natural for me. Besides the selective color interface seems a little slugish, it's much easier working with the curves. But you know what I have never seem any major issues with picture quality after converting to CMYK, which I do routinely for shots that I need that extra bit of control.

But the easiest way would be to just set your white balance so you don't even have to do any editing.
At worst, you screw up and die.

Converting to CMYK and then printing makes sence, but converting them back to RGB and using for the web decreases the quality whether your eyes see it or not.
Since everybody is striving towards better quality i think it's important to point this out.
