Range Finder can find real size or distance of objects in your digital camera photos. After a trip and when you are looking at your travel photos, sometimes you want to know the distances or sizes of the objects in there. It is somehow possible.

If you can find some objects in your photos whose sizes you know, you can measure their distances and if you know the distance of an object, you can find the size of it. For example if you know the height of a special building (e.g. Pharos or a tower) and you are some kilometers away from it, you can measure your distance using a simple photo.

But the rules are the same for a single lens or a group of lenses. There are four variables that are important in our calculations;
- The size of the object
- The distance of the object from the lens
- The size of the image on the sensor or the film
- The distance between the sensor and the lens

When you are talking about digital cameras, the first thing you may consider is its Megapixels. Usually people think that more megapixels are better but there are some issues in this megapixels race that manufactures dont admit.

When the sensor size is the same, more megapixels not only dont mean a better image, sometimes it makes a lower quality. For making more pixels, the manufacturers have to make smaller pixels on the sensor, it means each sensor’s pixel collect less light. In this situation, the ability to process on light is less and noise of each pixel rises. And you have an image with more pixels and more noise. This issue shows itself especially in low light situations.

If you want to pay more money for your digital camera, spend it on its sensor size. A digital camera with 8 megapixels and 1/1.7" sensor size is preferred to a 12 megapixel with 1/2.5" sensor size. 8 million buckets of water are more than 12 million cups of water.
