In fact, I've always believed that teaching photography to beginners isn't an easy task. Although I think photography is a simple and joyful activity, many newcomers either lack confidence or have been mislead into thinking it's a complicated journey. As a result, they often see it as a tough path rather than a fun experience.
That’s why there are certain things I believe every beginner should understand:
1. **Do you really need to learn with an SLR camera?**
Actually, no. Learning photography requires full control over exposure and focus. Any camera that offers manual settings like Shutter Priority (S), Aperture Priority (A), or Manual (M) will work just fine. Even some high-end compact cameras can be used effectively. However, I don’t recommend beginners buying small compacts or micro-singles right away. The choice depends on personal preference, but the key is not to get stuck with an SLR if it turns out to be too bulky or inconvenient. Many people regret their equipment choices later, but the truth is, what matters most is how well you use what you have. Once you start taking good photos, you'll naturally know what you need.
2. **Is it necessary to shoot in Manual mode (M)?**
Not really. In fact, over 95% of my photos are taken in Aperture Priority (A). A few are in Shutter Priority (S) when needed, and only a handful in Manual for specific situations—like extreme lighting conditions or when using flash. If you understand exposure principles, you’ll realize that each mode is essentially the same. If you don’t, it’s better to study the basics first.
3. **Is manual focus more accurate?**
Absolutely not. For most situations, especially for beginners, autofocus is far more reliable. Camera manufacturers spend years perfecting their systems, so trusting them is usually the best choice. Manual focus is mainly useful in rare cases, like capturing fast-moving subjects where autofocus might fail.
4. **Is a smaller aperture better for image quality?**
Not anymore. In the digital era, smaller apertures cause diffraction, which reduces sharpness. Modern lenses are designed to perform best at wider apertures. So, unless you're shooting landscapes with deep depth of field, there’s no need to stop down unnecessarily.
5. **Should you always use flash in low light?**
No. Many photographers, even professionals, misuse flash. Flash has a limited range, and using it incorrectly can ruin your shot. Remember: GN = Aperture × Distance. If your subject is too far, your flash won’t reach it. It’s important to understand flash capabilities before relying on it.
6. **Is a UV filter essential?**
Not really. A UV filter is mostly for protecting the lens from scratches, not for improving image quality. Unless you’re shooting in harsh environments, there’s no need to buy expensive ones. Just keep it simple and avoid unnecessary spending.
7. **Can post-processing fix everything?**
Post-processing is important, but it shouldn’t replace good shooting. Beginners often focus too much on editing, neglecting composition and technique. A strong image starts with a solid original shot. Post-processing should enhance, not compensate.
8. **Should beginners break the rules?**
Not yet. Breaking the rules comes after mastering them. Without a foundation, breaking the rules just looks unprofessional. Learn the basics first, then explore creativity.
9. **Is there a camera suitable for beginners?**
There’s no such thing as a “beginner camera.†What matters is how well you use it. Choosing a cheaper or simpler camera may limit your growth. Invest in something that allows you to learn and grow, not just look good.
10. **Is going to a studio without any knowledge useless?**
Yes, it probably is. Studios expect skill and knowledge. Without a basic understanding, you won’t be able to contribute meaningfully. Self-study through books, online courses, or free resources is a better starting point.
11. **Is content more important than technique?**
Absolutely. Great photos come from great moments and scenes. No amount of technical skill can save a weak subject. Always look for meaningful shots and experiences.
12. **Should you chase style or mood?**
Style and mood are important, but they come after skill. Without a solid foundation, chasing style can lead to frustration. Photography is a way to express yourself, and the more you learn, the more you can convey your vision.
In the end, photography is about seeing, learning, and growing. Start with the basics, stay curious, and enjoy the process.

Signal
Response time refers to the response speed of the Liquid Crystal Display to the input signal, that is, the response time of the liquid crystal from dark to bright or from bright to dark (the time for the brightness from 10%-->90% or 90%-->10%) , Usually in milliseconds (ms). To make this clear, we have to start with the human eye's perception of dynamic images. There is a phenomenon of "visual residue" in the human eye, and the high-speed motion picture will form a short-term impression in the human brain. Animations, movies, etc. to the latest games have applied the principle of visual residue, allowing a series of gradual images to be displayed in rapid succession in front of people's eyes to form dynamic images. The acceptable display speed of the picture is generally 24 frames per second, which is the origin of the movie playback speed of 24 frames per second. If the display speed is lower than this standard, people will obviously feel the picture pause and discomfort. Calculated according to this index, the display time of each picture needs to be less than 40ms. In this way, for the liquid crystal display, the response time of 40ms becomes a hurdle, and the display above 40ms will have obvious picture flicker, which makes people feel dizzy. If you want the image screen to reach the level of non-flicker, it is best to achieve a speed of 60 frames per second.
I used a very simple formula to calculate the number of frames per second under the corresponding response time as follows:
Response time 30ms=1/0.030=approximately 33 frames per second
Response time 25ms=1/0.025=approximately 40 frames per second
Response time 16ms=1/0.016=approximately 63 frames per second
Response time 12ms=1/0.012=approximately 83 frames of pictures displayed per second
Response time 8ms=1/0.008=approximately 125 frames per second
Response time 4ms=1/0.004=approximately 250 frames per second
Response time 3ms=1/0.003=approximately display 333 frames per second
Response time 2ms=1/0.002=approximately 500 frames per second
Response time 1ms=1/0.001=approximately 1000 frames per second
Tip: Through the above content, we understand the relationship between response time and the number of frames. From this, the response time is as short as possible. At that time, when the LCD market first started, the lowest acceptable range of response time was 35ms, mainly products represented by EIZO. Later, BenQ's FP series came out to 25ms. From 33 to 40 frames, it was basically undetectable, and it was really quality. The change is 16ms, displaying 63 frames per second to meet the requirements of movies and general games, so 16ms is not obsolete. With the improvement of panel technology, BenQ and ViewSonic started a speed battle. ViewSonic started from 8ms to 4ms. Released to 1ms, it can be said that 1ms is the final controversy of LCD speed. For game enthusiasts, 1ms faster means that CS's marksmanship will be more accurate, at least psychologically, such customers should recommend the VX series of monitors. But everyone should pay attention to the grayscale response when selling. The text difference in full-color response may sometimes mean the same thing as gray-scale 8ms and full-color 5ms. It is the same as when we sold CRTs before, we said that the dot pitch is .28, LG just I have to say that he is .21, but the horizontal dot pitch is ignored. In fact, the two are talking about the same thing. LG has come up with a sharpness of 1600:1. This is also a conceptual hype. Everyone uses the basic screen. There are only a few companies on the list, and how can only the LG family achieve 1600:1, and everyone stays at the level of 450:1? When it comes to consumers, the meaning of sharpness and contrast is obvious, just like AMD's PR value, which has no real meaning.
