The infinity mark on the lenses (if any) is only approximate! There are many reasons for this: One is manufacturing tolerance, which means that not even lenses of the same make are the same. In addition, today’s sophisticated lens systems are more sensitive to temperature changes, so the exact position of infinity also changes slightly during the day. So the sharpness preset during the day and fixed with a gaffer-tape will be inaccurate at night in the colder weather. IIInteresting technique but what are the chances of damaging the camera sensor when photographing directly into the full sun ? Reply Most diffusion filters will thread onto the end of the camera lens. Make sure you buy the right size filter for your camera lens.

In the top row of images, in the middle three images the difference in size between the stars is barely visible. Maybe because you are young, have good eyesight and your camera has a great live view, you can still see it, but for most people it’s a big uncertainty with a lot of errors.Depending on the preference of the photographer, these rays can provide extra drama or add a special flare to the final image. They are useful for street lamps at night, jewelry, chrome, cars, or other objects with strong specular highlights. When the filter is rotated, the rays turn with the filter so the photographer can control the direction of the rays. Many people think they are focusing correctly, and yet when they see their somewhat unsharp images, they think buying a new lens is the only solution. Star filters are made from two pieces of glass, the top one of which is rotatable and has the lines we've talked about etched onto it. To use a star filter, mount it onto your lens and rotate the front ring to change the direction of the stars. You'll probably also have to experiment with the aperture you're using as you don't want the lines on the filter to appear in your shot.

Even with standard DSLR cameras, you’ll be able to capture superb photographs of deep space. While researching the literature I found some promising devices on the internet, which are also recommended for wide-angle lenses by their manufacturers. They are all very similar: the well-known grid lines of the Bahtinov mask were laser-carved into a plastic sheet, relatively densely. They are available in square format or as a screw-in circular filter. I have tried a few of them. Although they work really well with longer focal lengths, I was disappointed using wide-angle and ultra-wide-angle lenses used for landscape astrophotography. The pattern was too small and too faint for any of them to be useful for my 2.8/14-24 lens. The Star Soft Astrophotography Filter is designed just like a GND filter with the effects full strength on the top 100mm of the filter, while the bottom 50mm is clear with no effect. This will allow placement so the effect can enhance the stars without affecting the foreground. Some photographers tell us they love the effect also on the foreground so the filter can be pushed all the way down in the filter holder to have the effect over the entire scene.
