With a 50mm lens, you can photograph a variety of subjects such as portraits, street photography, landscapes, and everyday scenes. The 50mm focal length is versatile and can capture a natural field of view similar to what the human eye sees, making it a popular choice for many photographers. Its wide aperture capabilities also make it suitable for low-light conditions and achieving a shallow depth of field for creative effects. **

If you want to photograph star trails or capture passing clouds, you will need a long exposure time. For star trails, you will need to use a shutter speed of at least 30 minutes to several hours, depending on the effect you want to achieve. For capturing passing clouds, a shutter speed of around 30 seconds to a few minutes should be sufficient to create a sense of movement in the clouds. Keep in mind that longer exposure times will require a stable tripod to prevent camera shake. **

To best photograph light painting with a sparkler, one should use the manual camera mode to have full control over the settings. Set a long exposure to capture the movement of the sparkler, typically around 5-10 seconds. Use a small aperture (high f-stop number) to create a deep depth of field and keep the sparkler in focus. Adjust the shutter speed to control the brightness of the sparkler trails, experimenting with different speeds to achieve the desired effect. **

A good lens for photographing people on the street is a prime lens with a focal length between 35mm and 85mm. This range allows for capturing candid shots of individuals without being too close or too far away. A prime lens also tends to have a wider aperture, which is useful for creating a shallow depth of field and isolating the subject from the background. Additionally, a prime lens is often lightweight and compact, making it easier to carry and maneuver in crowded urban environments. **

To photograph crystal figures like Swarovski and capture their sparkle, it is important to use a clean, plain background to allow the crystals to stand out. Natural light or diffused light sources work best to enhance the sparkle and reflections of the crystals. Adjusting the angle of the camera to catch the light reflecting off the crystals can also help to capture their sparkle effectively. Additionally, using a macro lens can help to capture the intricate details and facets of the crystal figures. **

To photograph the moon with an 18-105mm lens, you will need to set your camera to manual mode and adjust the settings accordingly. Start by setting your aperture to around f/8 to f/11 to ensure sharpness, then set your ISO to a low value, such as 100 or 200, to reduce noise. Use a tripod to keep your camera steady and prevent any blurriness. Lastly, adjust your shutter speed to properly expose the moon, which may vary depending on the lighting conditions. Experiment with different settings to achieve the desired result. **

Yes, you can photograph the moon with a 70-300mm macro lens. While a macro lens is typically used for close-up photography, the 70-300mm range allows for telephoto capabilities, making it suitable for capturing distant subjects like the moon. To photograph the moon effectively, it's important to use a tripod to minimize camera shake, and to adjust the settings on your camera to account for the brightness of the moon. With the right technique and settings, a 70-300mm macro lens can produce stunning moon photos. **

You can photograph shooting stars by using the technique of "shutter spamming" which involves continuously pressing the shutter button to take multiple photos in quick succession. By doing this, you increase the chances of capturing a shooting star in at least one of the frames. Shooting stars are fast-moving and unpredictable, so taking multiple photos increases the likelihood of capturing one in action. Afterward, you can review the photos and select the best one that captured the shooting star. **
