Exposure triangle

 

Using a tripod and a small aperture like F/5.0 can let you focus one single object and blurring the back round

Using a wide aperture allows the camera to have have every thing on the viewfinder sharp and not blurred a specific part

i took this picture of the night sky using a high iso like 3200 . that type of iso can be used in night time conditions that allows more light and detail in the sensors

using a low iso like 100 allows less light and that is what makes the image darker compared to previous picture of the night sky in my back yard

having the camera in manual mode allows you to set your settings as needed for this picture i made a small home made water studio with a cup of water and a pice of paper for a white background i used a shutter speed of 1/200 and i used an iso of 3,200 and a little help from a lamp for extra lighting since i was using a high shutter speed

i decided to do light trails for blurred motion . i took this picture behind my house which is right next to the freeway i used a shutter speed of 4.0 seconds and a tripod for the sharpness
