We always see some beautiful milky way photos but maybe sometimes we will ask, why they look so different in colors? It is about the color temperature problem. Experienced photographers know that it is supposed to keep White Balance with the right settings to get photos with rich colors and look like the real world. You have to tell the camera what is black and what is white. Color temperature is easy to change with the change of light. If you go under the sun, the color is warm. If you go into shadows the color also becomes cold. Without…

Planetary and moon photography always about stacking. Atmospheric disturbances can affect the stability of images at great distances. Also, most of the cameras used for planetary photography have smaller sensor formats with high pixel density. The signal-to-noise ratio is always insufficient. The current mainstream practice is the use of specialized Astro cooling cameras connected to the computer, shooting thousands of frames of AVI files, and then stacked them with software. However, computers and equatorial instruments are not the equipment that you bring out every day. Also, it is a bit too tiring to set up a telescope, equatorial mount, and…

In late 2016, Olympus launched the mZD ED 12-100mm IS PRO. I bought it immediately and used it on several trips, taken many satisfying street-photography shots, and recorded many occasions at work.
Once I went to a studio for attending a pre-wedding photographing event. I was interested in the studio lighting operation. The photographer told me his exposure settings and let me had a try. He shot with a 35mm format DSLR and I used 4/3 format camera E-M1. As a result, we found that we obtained the same result while we used identical exposure settings. I often see someone stated that because of crop factors, the shutter speed of smaller format systems will be slower, or the ISO sensitivity will be higher with the same aperture settings. I would like to…
(Article updated in May 2021) The epidemic in 2020 brought great changes to the world. At the same time, the weather and atmospheric conditions were quite well because of the reduction of industrial activities. In 2020, I got many chances to photograph the Milky Way, especially in the urban area of Macau, even with seriously light pollution. I accomplished the missions with M4/3 cameras and the STC-Optics Astro-Multispectra filter, that I want to introduce now. I bought it and test it out immediately after the Taiwanese optics manufacturer STC-Optics launched the Olympus M4/3 clip filter.
