- Can others edit my Photos
- Photos NOT OK to edit
My knowledge of optics and light transmission are not adequate enough to solve this problem so am asking for help from a more knowledgeable photographer.
Which is going to give me the best light gathering given the same ISO setting.
1 A 17mm f 2.8 lens set at shutter speed 30 secs (500 rule) ( Sigma 17- 35 mm f 2.8)
2 A 24 mm f 1.8 lens set at shutter speed 20 secs (500 rule) ( Sigma 24 mm f 1.4 Art) stopped down to reduce coma.
I am aware there are better lenses for this type of photography but these are what I have.
Thanks in advance.
