the first one. 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. grafting – layering 4/5 early photographers relied on the outdoor use of sunlight/daylight to expose light sensitive paper. photograms were able to be created in a darkroom, first with an oil lamp and then an electric bulb. 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>* information is below. Ok, well the very first thing I found was this link:
