Today I got a Macro Lens and started using it...
Now what I found:
- Difficulty in getting right Depth-of-Field
- Shake is making the shot worse..
Dept of field is a powerful tool when taking macro images, and it’s a technique we need to understand in order to work true macro magic. We will generally be using very shallow depth of field settings when getting up close to the subjects, and the closer we get, the shallower depth of field becomes.
At times this can be frustrating. For Example, we think we have captured a great image of a flower in full bloom, but then find that parts of the image are too soft. One way of getting around this is to stand a little further back and use more zoom, but be prepared to pay the penalty in terms of Camera Shake...
A much better option is to adjust the aperture setting manually. Selecting a smaller aperture, such as f/16 or even f/32, will increase the depth of field and ensure that the subject stays sharp. Larger aperture settings, such as f/2.8, will provide sharp focus area that can be measured with millimeters.
However, as soon as the aperture gets smaller, shutter speeds start to get much longer in order to compensate for the reduced amount of lighting coming through the lens. At settings of ISO 100 and f/16, shutter speed will be roughly 1/60secs or even slower, which can be a bad news if we are taking a hand-held shot because the risk of camera shake increases considerably.
We can still take the shot by using a tripod. If a tripod is unavailable, steadying the camera against a wall, fence or even a camera bag will make things much less shaky.
Autofoucs saves a great deal of time and hassle in norma shooting modes, but it’s often a good idea to use manual when shooting up close.
