Dynamic Range

By | Tips & Tricks | No Comments

Tip:

The above image is an example of exceptional performance of Nikon D800E sensor (manufactured by Sony).

Dynamic Range of Camera sensors are extremely important for Photographers like me where I can completely concentrate on capturing the moments I want in the field than bothering about the camera settings for each shot.

I want to make this post self explanatory with Images than text, please judge yourself.

Below are with Nikon D90 – 7 year old sensor technology

This below example is an accidental shot, still a keeper :) :)
Example 1:
Image out of the camera
Image out of the camera 100% crop
Image pushed around +5 stops in Post processing
Image pushed +5 stops in Post processing 100% crop
Ideally this image should be shot with more Depth of field, please check this link – Tip: Shooting at Small Apertures

Example 2:
Image out of the camera
Image pushed in Post processing, details are in the image itself
Final image

Below are with Nikon D800E
Example 3:
Image out of the camera
Final Image, pushed +3 stops in post processing
Extreme left bottom corner Out of the camera
Extreme left bottom in the Final Image 100pc crop
Before Shadow lifting, lower bottom
After Shadow lifting, lower bottom
After Shadow lifting and Processing, lower bottom
Saw the Black Kite? Advantage of 36 MP Resolution!

Keep shooting…

Shooting at Small Apertures

By | Tips & Tricks | No Comments

Tip:

The above shot was taken in Shutter Priority and I let Aperture to set by camera automatically, in this case to f/36 (Ideally one should shoot this in manual mode with ND filters which I did not have at that point).

Interestingly in Photography “Small Aperture” means a big number. For ex. F/11, f/13, f/16, f/22 etc are few small apertures and f/1.2, f/1.4, f/2.8 etc are Large/Wide Apertures.

Shooting “Small Aperture” is required in few kinds of photography like Landscapes, some Macros, Architecture photography etc where more depth of field is required.

Few drawbacks of using small apertures are
1. Need more light, so it is a challenge when shooting in low light
2. Diffraction, which mean loss of sharpness

Overcoming the drawbacks:
1. Use a tripod with a timer or wireless/wired remote triggers when light is low and more depth of field is needed
2. Use good lenses which can handle smaller apertures without a huge degradation of Sharpness
3. Use good post processing techniques for sharpening.

Below is an example shot at f/16 with Nikon D90 camera and Nikon Af-S 50mm f/1.8 prime lens. Generally prime lenses are good in optics.

Image out of the camera

 
Out of the camera – 100% crop Eye portion
 
Out of the camera – 100% crop Tail portion
 
Processed Image
 
Processed Image – 100% crop Eye portion
 
Processed Image – 100% crop Tail portion

 

As you can see this image, the final result is sharp with good depth of field from eyes to tail. So with good shooting discipline and post processing, one can achieve good results even shooting at smaller apertures.
