Hi Anand,

Interesting these star trails.

Nicely done, thanks for sharing.

 

[gilbert]

Wow, these are way cool!

Beautiful! I always keep meaning to do a star trails shot. How long did you spend doing the whole thing?

Very nice images. I have always wanted to shoot star trails but I have no idea how.

Whats your technique ?

Thanks in advance

Thanks all.

This was done using ISO 400, f/5.6 and 15 minutes in bulb mode.

We took a test shot for 10 mins and "guessed" the exposure to use for the next shot.

There were 3 of us doing this shot, so I tripped off my camera after 15 mins, if it was under-exposed, we would have waited for a few more mins before tripping the next camera

I manual focused on hyperfocal distance, but locking focus on the barn would have worked too.

Looks great. Have you tried stacking this and the first test exposure?

how far from the barn did u trigger the flash? was it from same place where ur camera is placed?

The first shot was simply too under-exposed . thanks.

Kaushik

Welcome. This was not lit by a flash. This was painted with light by using a subdued flash light. Wonderful technique, gives the moody feel.

Wow! That's amazing anand! I want to go try it right now - do you mind?

Glad I help .

This was at 8000+ feet, the air is so clean and you see all the stars. All you need to do is to find a matching foreground to suit the mood.

Really nice shots, Anand

I really like the star trails. This gives me something to try
from the patio.

Cover the flash light by hand and let a small streak of light through so that you don't flood the subject, use it carefully not to blow highlights / overexpose.

Thanks. Wow, do you see stars from your patio?

Anand,

I live in a small town in the Colorado Rockies. The stars are plentiful
and beautiful.

Wow Ray, wonderful.

Please post them. Please leave long exposure NR on, it does dark frame subtraction and does a magnificient job. It doubles the exposure time though
