It was a beautiful day, a complete change from yesterday and a beautiful day with not a cloud in the sky.
The most important point in macro photography is the shutter speed. When taking hand-held landscape photos, it is said that if the shutter speed is faster than 1/(focal length) second, camera shake is less likely to occur. This means that if you have a 50mm focal length lens, you should choose a shutter speed faster than 1/50 second. However, this logic cannot be used in macro photography. The reason for this is that macro lenses have a higher magnification (larger image) than other lenses and the subject is moving very finely, mainly affected by the wind, which can cause subject blur.
As I mentioned before, the shutter speed for macro photography should be 1/1000 second. At the very least, it should be faster than 1/500 of a second. The key is to remember to check the shutter speed once you have determined the distance to the subject. If the shutter speed is less than 1/1000th of a second, increase the ISO sensitivity (increase the number). If the ISO sensitivity is 200 and the shutter speed is 1/250 of a second, the shutter speed will be 1/1000 of a second if the ISO sensitivity is 800. If the ISO sensitivity is 200 and the shutter speed is 1/250 sec. When I have a good chance to get a good shot, I lower the ISO sensitivity.
I used to use a digital SLR camera from Company C. The ISO sensitivity was limited to 200, and 400 was just about acceptable. Now I am using a mirrorless camera from Company S, which is said to have good sensitivity, but I usually use ISO up to 800, and 1600 is just about acceptable.
On a sunny day like today, it is easy to increase the shutter speed and it is a good day for macro photography. If you can adjust the ISO sensitivity while looking through the viewfinder, you can reduce the risk of missing your chance.
