跟楼主请教settings,我昨晚捣鼓了一晚上也拍不出清晰的星星,快门快了太黑,慢了星星又挪位。还有因为太黑自动对焦不能用,手动黑漆漆的什么也看不见。楼主请指教啊。
Setting for my photos.
1) 20mm - f5.6 - 30s - ISO800
2) 20mm - f5.6 - 30s - ISO1600
3) 20mm - f4.5 - 30s - ISO800
This is my normal setting for NO star trails photo, just an example, feel free to break them
1) Setting
Tripod
RAW (to correct whitebalance)
M mode
shutter cable
turn off noise reduce function
turn off D-light
manual focus - infinity!
bring a touch/led light to light paint the front ground if need.
2) Lens vs shutter speed
(mime is Nikon non-full frame, so 20mm = 35mm in fullframe)
20mm - 15-30s
35mm - <20s
50mm - <15s
The longer your lens, the faster the speed
otherwise ... the tail is too much and doesnt look good.
3) aperture
with front ground - f4.5-5.6
just star and some black background - wide open
4) ISO
depending on the light, but generally 800 or 1600.
5) post processing !
crop, correct expose ...
if you want the long star trail, there are few ways to do it
1) super long exp and I am talking hours, you can get a circle if facing directly to north or south .... (most common way, especially in old time with film)
2) take a normal photo every 5min and use software to combine them (better result)
3) take a photo of landscape at night .... use photoshop and draw the star trail (doable, but I dont think ppl like it if they know this is fake)
hope this help. |
