You don’t like grey, cloudy days as a landscape photographer. VIEWFINDR calculates the contrast in a landscape from cloud cover. Is the sky free of clouds, you will find the most contrast while shooting landscape. Bring out the colours and structures in your images. Download VIEWFINDR App today.
From the weather parameter drop down menu choose photo contrast. The more transparent the map is visible, the higher the chance of a clear sky.
Tap on the photo spot icons inside the area with a high probability. The photo spot preview opens up. Tap the preview. Scroll through the images of the photo spot. If you like what you see, just visit the photo spot by the time shown on the scroll bar.
For the best outcome, only visit if the probability is close to 99%. If not, the chance for clouds blocking the sun is high.
This parameter guarantees a cloud-free sky with high-contrast direct sunlight.
Like any parameter with a gray color overlay, this is a template parameter. Areas where the map is clearly visible have a high probability. Areas where the map is grayed out have a low probability.
Based on the visualization we use, the “Streets” and “Outdoor” background maps provide the best contrast to see the color overlay well. The background map can be changed at the top of the menu bar.
The scale can be used to translate how high the probability is. Simply compare the map with the scale and read off the value. Please remember: a probability of 20% means that you will come up empty in 4/5 cases!
By scrolling the time scale you can change the date. An up arrow marks the sunrise, a down arrow the sunset on the respective date.
In the highly visible areas of the map, the probability of occurrence of the weather phenomenon is particularly high. Pick out photo spots in these areas. The weather overlay covers the photo spots up like a template. The better a marker can be seen, the higher the probability for the weather phenomenon to occur at this specific photo spot.
By setting the filter in “Views” to “Weather specific”, only those photo spots will be displayed that can be photographed with the selected weather phenomenon.
The weather forecast in VIEWFINDR is a computer simulation that very realistically forecasts the coming weather. However, the forecast is not exactly the reality and there will be deviations.
In VIEWFINDR new weather data is provided every 3h. For example, if you check for the probability of afterglow after sunset in the morning hours, the forecast will change several times over day. This is perfectly normal and that’s a good thing!
The closer the deadline, i.e. the sunset in the evening, the smaller the deviation of the computer simulation from reality becomes. The forecast becomes more precise. Before you finally set out to take pictures, you should therefore take another look at the current forecast.
You should therefore check the forecast again before you start your photography tour to see, if the probability is still high. Don’t be mad if the forecast probability changed into worse, it probably saved you from a bad outcome!
The weather forecast in VIEWFINDR is limited to 24h for local weather models and 72h for continental weather models. It is not useful to look into the future for a longer period. The forecast becomes inaccurate and is not reliable. Weather apps that allow forecasts of more than 3 days but do not provide any indication that the forecast is extremely inaccurate are a disgrace. This gives the
Just as the resolution of your camera is limited, i.e. it cannot take an “infinitely” sharp photo, the resolution of the weather model is also limited. This is 2.8km for Central European weather data and 7km for European weather data.
Structures and features of the landscape that are not that large are averaged by the model. For example, if a mountain is 800m high, and the valley next to it is 400m high, then the landscape for the weather model in that “pixel” is 600m high, corresponding to the average altitude.
This means that small structures, like narrow mountain valleys or local small river valleys cannot be properly captured by the model. This is not a problem, you just have to learn to deal with it. If a valley in the mountains is much smaller than the resolution of our weather model, then you have to interpolate.
Small valleys always end in larger valleys. You can therefore use the weather in the next larger valley as a good reference for the weather in a smaller, adjacent valley. In the example, you can see that the large valley is filled with fog. It is almost certain that the small valley is also filled with fog.
Due to the limited resolution, it makes sense not to use too much zoom. It is important that you look at the overall context. Therefore, consider the weather forecast not only for your location, but at least for the entire region where you are shooting.
This example show how the weather model sees the landscape. It is pixelated because of the limited resolution.
Due to limited resolution, this layer of low clouds/fog will not indicate fog in valleys with a size below the resolution.
When uploading a new photospot you guide other photographers. Connecting a photospot to the photo contrast parameter is not “making a wish”. Only connect photospots which actually can be photographed with a direct sun light. Look at our example images.
The idea of this weather parameter ist to give landscape photographers a tool to see if the sky will be cloudy around their chosen photo spot or if not, the sun will shine with a contrasty light. We use 3D cloud data to not only check the cloudiness at the exact location of your photo spot, we also calculate the surrounding clouds close to the horizon. When the parameter shows a high probability, there won’t be any clouds on the sky around your photo spot.
