Exposure: Learn Photography 3

I am back in town and I was expecting some time to explore more about “exposure”. BUT our default weather is back and unfortunately I might not get chance to take my camera out for next 10 days (according to trusted weather forecast sites 😦 ).

I like the explanation on “Exposure” by Raj@XDrive and would love to go in field for practicals with birds as my subject. For time being I am using my old clicks from 2 years ago.  I had seen some pictures of blur or milky effect water falls and I was eager to capture such impressions. I read some articles and blogs. Due to the complicated explanation (and lack of patience on my side at that time), I decided to try different apertures and shutter speeds, and to learn a little bit on my own. I knew nothing about ISO then, not much even now as I have not experimented with it. In all my images it is 100.

It was a bright sunny day. learnphoto3_1 The settings were 1/125 sek. f/5,6 55 mm. Lens was set at maximum aperture and hence so much light. (Am I correct?)

 

Example of changing the shutter speed but keeping aperture constant. (please click the images for a better view and to check the settings).

And my final photo for this session. Here I used Shutter priority.

Getting blur effect and being happy!

The settings were 3/10 sec.,  f/36,  55 mm

All these pictures were captured using 18-55 kit lens. What shall be the difference if we use another lens? say 55-300 mm.  How to make good use of 55-300 mm lens? Will there be any post about various lenses and their uses?

Happy Teacher’s day Raj!

    Thanks Rupali for a very descriptive post and the submission! Great to see you. And I like your post with questions that way I don’t have to invent a question! 😀

    Regarding the exposure, Theoretically, the picture should not have full whites or full blacks. All pixels in your picture should be within that range. Once you hit a full white that is maximum brightness you have hit the limit, there after there is no more details. Same thing happens when you hit the lower limit(black) too. Pic 1; a Typical snapshot of flowing water. A lot of white area in the picture. We call this an over exposed shot. It all depends on your exposure mode you used while clicking the shot. If it’s Auto, or shutter priority or aperture priority, the camera will adjust the parameters to give you a perfect exposure. In this case though, it looks like you were in manual mode. It’s not because you choose f5.6, in this instance, if the shutter speed selected were 1/500 sec would have created a proper exposure. Hope you got the point. It’s not just the aperture or shutter speed alone controls the exposure.

    Picture 2 and 3 are, as you said the result of different shutter speeds. Faster shutter speeds freeze the water movement where as the other flow the water.

    Pic 3, as a result of slower shutter speed, has converted the image to art. In that view in mind, it’s a beautiful picture. But here, if you look at the right bottom, even the plant also looks blurry, that is not a good thing. Because the plant is a stationary thing and it should have been sharply focused. The reason for that is, you were using the slow shutter speed, and the camera was handled by hand, not on a tripod. You have to be careful whenever you reduce the shutter speeds about the camera shake.

    Regarding the zoom lens, in this case, I would use the 18-55mm itself because we are shooting a landscape kind of shot. By using the zoom lens your field of view becomes narrow and also you have to make sure you are using faster shutter speeds.

    Great idea about a post on different lenses. I will do that.

    Thank you for your teacher days wishes, yes everyone is a teacher and a student.. so wishing you a happy teachers day too.

    This critical review is part of XDrive Learn Photography session. Thank you for your participation

      Thank you Raj for commenting.
      I shall be experimenting with aperture and shutter speed combinations in manual mode asap. Then I might write another post with proper image details.
      Looking forwad to read new post which you have already posted 🙂
