Great bebel 2009-07-18 3:21

Bonjour Christian
le hasard fait que je tombe sur cette photo étonnante et attirante par son sujet, plein de mystères. outre les qualités techniques, elle est aussi en phase avec l'objet de TE. Comment se fait-il qu'il y ait une fine hauteur d'eau et sur une aussi grande étendue ?
bon dimanche

Default To paololg: what about movement blur?

Hi Paolo,

As always, you have given excellent feedback. Thank you!

I'll ask you the same question I asked Marianne S: If you leave the shutter open that long (several seconds), and there are people in the scene, or even things like tree branches swaying in the breeze, how do you prevent blurring of the objects/people that are in motion?

I took some other shots that same night of the fireworks, for instance, and I did some experimenting with various settings. The ones I took where the shutter was open for several seconds came out great of the fireworks and background, but the foreground people sitting on the beach were a little blurry. (F9, 5 seconds worked the best) All it takes is a turn of the head to cause blur when you shoot several seconds.

Also, why do you say ISO of 400 max for night shots? I tried a bunch of settings that night, but would love to know why you think 400 max....

Thanks again, and I wish you a wonderful week :)

Rachel

ISO 400 because noise is limited. Over ISO 400/800 the photo can be damaged from the noise and from the grain. 5 seconds are too long time to capture the subjects in movement, especially with the closed objective to F/9. Try to open completely the objective, you won't have a lot of depth of field, but the camera captures more light in smaller time. Unfortunately these are the limits of our cameras, that are not professional. There are objective very bright and professional cameras with great sensors, but they have the defect to cost thousand of dollars. With our cameras it is only possible to improve the nighttime photos in PP.
Ciao!
Paolo

OK, I understand! Higher ISO = more noise. Thanks for articulating that.

So basically if you want clarity and acceptable light in dark conditions, and if you have to leave the shutter open for seconds as opposed to milliseconds to accomplish that, then you have to accept that movement will cause blur. I get it.

Thanks again! I really appreciate your time and expertise.

Happy Monday :)
