how can i calculate the sun rising time for a specific point on earth?
i'm looking for a tool, application, etc. that allows me to calculate the sun rising time for any specific point on the earth. i've found a lot of such tools, but all of them do not take mountains, etc. into account that will block the sun. to clarify: i'm interested in the time when i'll be able to see the sun.


i'm asking this, because when traveling i like to take pictures during sunrise.
you might try the noaa site: https://www.esrl.noaa.gov/gmd/grad/solcalc/
the straight distance between two place on a map can be measured by a strip of paper and divider.use a ruler to measure the distance between the two places. if the line is quite curved, use a string to determine the distance, and then measure the string. find the scale for the map you're going to use. it might be a ruler bar scale or a written scale, in words or numbers. Photography is the process of making pictures (graph) using light (photo)...  
Light takes the most important role on produce nice pictures  
  
There`re no fixed rules about photography, it`s an art so nobody have rights to say that the photo is good or bad...  
  
During rainy day, you should prepare camera`s water-proof jacket or an umbrella to protect it against water. Some expensive cameras have been equipped with water-proof material. clock - in the same app, you can set alarms, see what hour is and count down. a simple and useful app that always is welcomed. alarm sound can be personalized. the schedule for tree of life awakenings is usually announced just a couple of weeks in advance. its timing is dependent on sundown as darkness is really needed to enjoy this amazing show on the tree of life. be sure to keep an eye on its page in the coming weeks to find its beginning time, which i expect will be around 8:30 p.m. flying insects use the sun or the brightest light source as a reference for navigation. the sun or moon work nicely since they are a great distance away making the light rays, for all practical purposes (like navigation), parallel to each other. the insect observes the angle of the point of light as it starts its journey and returns simply by flying the reciprocal or opposite angle for the same length of time.

the problem for the insect comes when it uses a nearby source of light such as a light bulb as it navigates. the rays from a bulb are no longer strictly parallel since light is emitted from all points of a relatively large global surface of the bulb. as the insect tries to maintain a constant light-to-eye angle it has to make constant corrections by turning in flight. this results in a spiraling flightpath bringing it closer and closer to the bulb until they are, shall we say "overcome by the heat", or they run into the window glass. on some cameras, there is a setting in the menu screen to adjust the brighness of the screen. i would also suggest just using the viewfinder to take pictures as well. google map is detailed enough for you to find ur way. it is the best that is available online especially with sat photos hi ron. the rain duration value is the number of integer minutes that rain was detected for the “local day”. it is not available in the api yet, but will likely be made so in the future. There could be a variety of leaderboards. Like one of top points overall, and another for the most points gained in the previous 4 weeks or something. I may never top to overall leaderboard, but I have a chance of getting on a monthly leaderboard. After 5 hours of learning I have compiled these:


Mindset



1. **Make sure the placed image ratio is good** to make it more realistic. This can be attained by checking with the other object in the output picture, like trees, or other peoples' height. You are not going to place human with the size much smaller than the other human at the same picture. Similarly, you also must not place a person with the height higher than a tree.
2. **Get the right perspective**. Sometimes, when an object is placed in an odd perspective, image is going to look very bold that it has been photoshopped or copy pasted.
3. **Lighting**. It is important to pay attention to light source, like the sun, and make sure our object is appropriate with output background light source. This can be done by adjusting the lighting of object and adding shadow with referencing other shadow in output image.


Tools (to make edges more realistic)



1. **Layer masking.** If moving people, hair can look awful if just plainly moved. Masking allows us to further tweak our selection.
2. **Refine edge.** *This tool allows you to control many aspect of the edge of your selection* (desired object to move), like Edge Detection (brushing the edges of object and let photoshop do its job, usually around dog fur), Feather (Soften the area of selection), Smooth (reduce pointiness of your selection), Contrast (somewhat opposite of smooth), and Shift Edge (moving feather far or nearer the selection, usually to remove excess background color near the edges). *REFERENCE: <https://www.youtube.com/watch?v=5lDr2Nd8Yl4>*
3. **Layer Matting**. Inside we have many sub-tools to work on, like Color Decontamination (spread out soft mask around the edge, usually for hair to catch other hair that accidentally masked or can be used similarly to Shift Edge), Remove Matte (soften edge of sharp graphic or pixalated, raster look). *REFERENCE: <https://www.youtube.com/watch?v=N6K_htNQPPA>*
4. **Image Calculation**. By playing with the blending, we can make the background darker; thus, helping us making mask. *REFERENCE: <https://www.youtube.com/watch?v=0zf-H9RoCNk>*
