姐係點....... 模糊?
令到相片鬆郁矇, out of focus是其中原因, 但非一定是或只是
Unsharp picture reasons:
1. out of focus. Learn your autofocus system, use it properly, understand its limitations, and adapt to it. Use manual focus and zoom in the liveview to confirm focus.
2. camera shake. Use adequate shutter speed. Use VR. Use a tripod.
3. lens unsharp. Use a sharper lens. Stop down to f/5.6 or f/8 will usually improve sharpness. But watch out for #2.
4. tripod not sturdy enough. Use a stronger tripod. Use a cable release, the self-timer, mirror-lockup or delayed exposure.
5. in-camera sharpening setting set too low. Can usually be fixed in post-processing, and not a problem unless you can't do PP.
6. lens or filter too dirty, or shooting through dirty glass/windows. Remove or clean the blockage.
7. loss of contrast (perceived as sharpness) due to flare. Use the lens hood and avoid shooting into the sun or direct light sources.
8. ISO set too high and heavy noise reduction takes away fine detail. Lower ISO if possible, or turn off noise reduction. |
