The F number or F stop means focal length of the lens or you can say that measure of light gathering ability of an optical system. F stop number in DSLR camera depends on the camera lens . It does not depends on Camera Body. Your camera lens has define minimum aperture value or F stop focal length on lens . F stop Number also prefer for light optimization and how much light you allow inside the sensor of the camera. Also F stop or Aperture low value and high value makes different in Image in focus parts. Low F / Aperture value like F/2.8 make sharp image only on focus part and rest part in blur and high F/ Aperture value like F/20 make sharp image all focus part . When you Increase and decrease the aperture value or F number in camera you might be increase and decrease in Shutter speed and as well as ISO too.
Understanding F number or Aperture with Shutter speed and ISO :
As shown in main image you can easily understand how aperture or F stop works . It shows that when you use wider aperture like F/2.8 the aperture is wider and more light comes through your lens so the image will be brighter when you use low aperture value. As opposite using high aperture like F/22 the light comes less through your lens and the images are darker. But the main difference in using F number is focus part. It means that when you use aperture at low like F/2.8 your focus image only be a sharp rest part of image will be blurred. And in F/22 your focus parts of images sharpen not blurred I will show you an example of that . But while using F number F/2.8 to F/22 you need to change ISO settings and also A shutter speed too.
As Shown in Above image you can easily understand how Aperture works with ISO and Shutter speed.
One image is taken with F/10, ISO -250 and Shutter speed 1/400 seconds . In that image you can see the subject clear and also other part of the image also clear in background in compare to other image.
The second image taken with F/2.8, ISO-250 and Shutter speed 1/ 5000 seconds. In that image you can see only subject is sharp rest image is blurred. But the changes i made to shutter speed increase because when i use wider aperture F/2.8 more light comes through lens and image will be more brighter so i increase my shutter speed.
Another example of Aperture is above image.
One image taken with F/2.8 , ISO-320 and shutter speed 1/2500 sec. In that image flower looks clear and rest of image looks blurry . The other image taken with F/20, ISO-1250 and shutter speed 1/250 sec. That image flower with plant leaves looks clear because i use F/20 but in that case i need to increase ISO and lower shutter speed. Increasing ISO may increase noise in your image so if it is not necessary then don't boost ISO use only shutter speed if passible.
Some Facts to know about Aperture or F stop :
- F number decides how much your photo in focus
- Lower F number makes image Brighter
- Higher F number makes image Darker
- Aperture depends on your lens
- Different lens have different aperture value.
- To increase and decrease your aperture value you need to adjust ISO and Shutter speed as per subject and light.
I use Canon 100 mm lens for both above image with canon 80D camera body. Canon 100 mm macro lens has F/2.8 minimum aperture value. All lenses have different minimum and maximum aperture value. ISO and shutter speed depends on your camera Body. Some Camera body support High ISO with low noise too.

What is HORIZONS ? :: The horizon is the apparent line that separates Earth from sky. The true horizons can observed when it lines on the sea surface. Also many locations this line is made by Lands, Trees, Buildings, Mountains etc.The Horizon line divides all visible directions into two categories : those that intersect the Earth surface and those that don't. The horizon line is horizontal like to feel like end of earth no end of Earth surface . The Images of Horizons or skyline taken at Little Rann of Kutch . I tried to shoot many locations but sometimes not gonna happen that. Little Rann of Kutch is good place for Horizon photography bcz flat surface and 360 degree view. Above photo we passed thorough rann and i saw car trek on ground and line goes end of surface looks beautiful.
Horizon Height and distance calculation :
Well if you want to see horizon then you have to observe from 5-7 feet above sea level. Also you need clear land about 3-5 km distance then you can see clear Horizon line. In cities there are lots of disturbance like buildings, trees, towers etc so you can not see the clear horizons. For horizon line to see you need clear land area or water area. Best area for Horizon line is in between sea. In ocean there is clear Horizon line you can see easily. Also sunrise and sunset time horizons are amazing to see because of Twilight sky colors. Well all of these photos are not taken from 7 feet height and distance may not 3-5 km but its still you can see Horizons clearly. Photos taken from ground level but the rann area is clear so you can see horizons line from ground level.
For calculation of Horizon distance equation is :: Square root ( Height / 0.5736 ) and the result you get distance of Horizons.
Best Place To See Horizon lines :
The best place to see horizons are beaches. Because you can see clear line between Sky and Earth. Well where i live in Gujarat i have also one place name Little Rann of Kutch where i can see clear Horizon line as you can see in photos of Horizons. Little rann of Kutch is best place for me because its very near to me like about 2 hours car drive. Here there are huge number of raptors you can see in winter seasons. Lots of Migratory birds came here and the most important about Little Rann ot Kutch is Indian Wild Ass. Indian wild ass found only in Gujarat in this region only.
