White balance is all relative. Light (natural or artificial) varies in colour and your eyes are used to adjusting it. It's amazing how an image can seem fine until you see another image with a different white balance and it suddenly looks wrong. Even the background colour of the page holding the image or frame can influence how colour balance is perceived. ...

I think if you look through pictures you'll find quite a bit of difference, but I suspect much of it is illusory. Specifically, you'll almost certainly find more pictures of really spectacular sunsets than sunrises. I'm not at all convinced that this is because an average sunset is more spectacular though -- it's a simple matter of the number of pictures ...

The Photographer's Ephemeris is a great software package to get started with these sorts of calculations. There is a free desktop version that you can use at home before your trip, and if it turns out to be really helpful, there are paid versions available for iOS and Android. This tool lets you mark a spot on a map and then calculate sunrise, sunset, ...

Since most visitors come to New York City and refer to it as New York, I will base my answers on the assumption you mean New York City (we can be pedantic around here :) ). Manhattan Island runs lengthwise essentially Northeast to Southwest, such that if one were standing in Midtown (say Times Square), sunrise would occur roughly east of Central Park ...

From my (family's) observations, generally sunsets have a larger spread of light. Also sunsets have more colour depth. For example: Sunrise (from Wikipedia) Sunset (from wikipedia) This is from our own observations, NOT from any documented sources.

The effect is known as Rayleigh scattering. Blue light has a wavelength of around 400 nano meters, which is more likely than red light (650nm) to be absorbed by particles in the sky and radiated toward the ground, leaving the red light to carry on and hit our retinas. The water vapour in fog, however, are much too large to scatter individual wavelengths and ...

The pixels are not overexposed in any channel, and applying a heavy curve will reveal the darker edges and some dark spots. What you have is an exposed-to-the-right image of how the sun looks like - it is a big shiny ball. IMHO you should have enough data in RAW to tweak this into a usable image.

Most P&S I have used does amazing jobs with the built-in presets (Scene modes)! Though most people think the presets are targeted towards amateurs, but trust me they are not! The companies have invested heavy amount of research and money to configure these presets often using real life feedback from very experienced photographers. So I'd not ...

It is indeed difficult, if not impossible, to tell at times. Here's a list a strategies I might use to tell the difference: Look for contextual clues. Even a tiny recognizable feature could reveal the cardinal direction. Atmospheric clarity. During a sunrise, the dust has had time to settle at night, making the sky clearer than at sunset, where there is a ...

Noise is only peripherally about ISO. What really determines noise is the Signal-to-Noise Ratio. The reason we assume high ISO is noisier is because we normally use high ISO when the signal (the amount of light falling on the sensor) is weak. But shooting at high ISO when there is plenty of light in a scene will produce less noise than shooting at low ISO ...

In low light on a phone camera with little in the way of user-adjustment, your primary objective is to keep the camera still. Find a wall you can rest it on, & if possible use a delay timer, so you're not actually holding the phone as the picture is taken. If there is nothing suitable to rest the phone on find a wall/fence/tree to lean against. Keep ...

At the equator, you would get 1 minute extra sun at either end of the day per 1.5km of altitude, according to this page. Using trigonometry, for every degree north or south you travel, the extra time the sun would stay above the horizon (per 1.5km altitude) would be (1/cos (latitude)) * 1 minute per 1.5km, giving the following values: 10° : 1.02 min = 1 ...

Dust in the atmosphere is the main cause of colorful sunrises and sunsets. According to wikipedia sunsets tend to be more colorful due to the presence of more dust in the atmosphere at the end of the day compared to dawn. Dust scatters (Rayleigh scattering) the small wavelengths of light (blues and greens), leaving the reds and oranges to come through. But ...

A circular polariser filter will reduce reflections from the surface of the water, making it appear clear. Here a good example of this:

On Android there's a great app called Sun Surveyor. This will tell you sunrise/set/golden/blue times, as others do. But it's got the map view (as shown elsewhere), and another unique feature, which is an "augmented reality" view where you hold your phone up, and it uses the camera to overlay on the real scenery the path that the sun is going to take during ...

I just got a new camera, a Canon EOS Rebel xti Congratulations! New gear is always exciting. ;-) Also, welcome to Photo.SE. I am still learning what it can do. First thing to do: Read the manual. I know that sounds obvious and maybe condescending, but I get the strong impression that lots of people never read the manual when they get a new camera. I'll ...

The Photographer's Ephemeris (http://photoephemeris.com/). The desktop version is a web app, and they also have iOS and Android versions. I plan every 'proper' shoot I do with it.

As mentioned in comments, it's lens flare, caused by the sunlight just managing to hit the lens, even with your lens hood on. Exacerbated by the HDR process. You might not notice it as you're taking the shot, but if you wave your hand in front, above & to the side & see if you can spot any point where it changes the light balance in the viewfinder ...

You can also use a free tool that I've developed with a colleague. It computes the actual sunrise and sunset times for any location worldwide, accounting for terrain. The example in the image is for Chamonix in France. Go to suncurves.com to find your own location. Hope you like it! I'm using it for all my outdoor shoots.

I've found Sol to be not only an excellent sunset/sunrise app, but it looks great too and I like the visual representation of the length of the day. Sol also has relative alarms that will alert you X minutes prior to a sun event (sunset, Golden Hour, etc). It can also be set to adjust for your location if you travel. Also check out SunCalc - it's not ...

The simplest way to do what you want it to make HDR. Bracket several exposures with +-1 or +-2 stops then use software to combine in single image with light and dark areas exposed closest to your vision. In such very high contrast scenes this can help a lot. Of course you can try with single RAW file and try to compress high contrast to acceptable level. ...

First of all you need to understand the concept of "dynamic range". (Maybe you do, I don't know) The dr is the ability of your camera to render as much darktones and highlights at the same time. Have a look about this concept on youtube. You have to be aware that the human eye has the hability to render a better DR than most of digital cameras. On average, ...

Sunsets vary greatly as I'm sure you know! Sometimes just being in the right place at the right time can help but you help yourself here sometimes. Luckily we live in a time of digital and you can see what you took instantly so just tweak from there. Start with a base exposure then slowly underexpose or expose as bright as you can then develop the rest ...

As one of the developers, I feel compelled to tell you about our photography app, GoldenPic. GoldenPic doesn't just give you the sunrise and sunset, it also provides you the blue and golden hours, moon phase, moonrise and moonset times, weather, GPS coordinates, etc. It even lets you save your GPS coordinates to recall at a later day/time and integrates ...

I use SunCalc. Probably one of the prettier browser based ones out there.

Yes, there is a form of spectrum distortion: At sunset the light from the sun has to pass through more atmosphere, which scatters the light, but this scattering effect is strong the higher the wavelength of light, therefore the blue end of the spectrum is scattered a lot more than the red, therefore the red end of the spectrum remains stronger at sunset ...

The moon can be tricky since cameras will meter for the moon and all the black sky around it. This will fool the cameras lightmeter. Since the same sun falls on the moon as on the earth, the basic starting point would be 1/ISO @ f/16. Usually the density of the air surrounding the earth and any particulate in it will require you to increase the exposure ...

I live in a place where I get to see and film sunrises over the Cascade mountains, and I like to make timelapse movies of those sunrises. After a lot of experimentation I have found that setting the meter exposure down two notches really helps to capture the color. I set the aperture somewhere between F22 and F16 depending on the lense, the light and how ...
