Description
Aperture and exposure times interact. Well, there are many manuals to be found on the web nowadays so I am not going to explain in detail how the interaction is between aperture, exposure time and film light-sensitivity (ISO). Exposure times have no effect on things that do not move, but moving objects have different effects. You can use a short shutter-time or a long shutter-time with streaming water like here (a crevice in the mountain made the falling water spurting almost horizontally), but a value in between results is an unfortunate compromise, like you can see here (1/30 sec if I'm correct).
Lesson 5 - Decide carefully what shutter-time you (approximately) want to use. Many camera's provide the opportunity to set the exposure-time so that the camera automatically will adapt the appropriate aperture (that will determine your DOF).
Thanks for your attention and your always valuable comments

I can't figure out if it's a geyser shooting upwards, or a waterfall at a 90 angle! However, it's another good lesson :)

Interesting capture of this water gushing out of the mountains crevasse horizontally. Not very often will one see something like this. There must be a strong force of water hidden behind this crevasse. Excellent lesson on the shutter speed. I haven't tried adjusting the shutter speed for moving subjects yet but have been doing it for dark/night shots. I'll take many pictures with different settings. Then I'll pick the best one (I'm still a rookie here). Thanks for your expert help. Aloha

a scene that I have not had the pleasure of viewing before and I think you done an excellent capture
pimbotin
You're right, you're totally right... but it needs a long practice before being able to make those decisions correctly. But you're right!
Akinom
Yes, Philippe said it right... it needs a long practice before being able to make those decisions correctly. Interesting lesson again, thanks!

Oooh, pimbotin is sooo right. I just tried learning that whole thing....and franky...it will take lots of time before i get a hang of it, LOL. Very cool capture by the way!!! Have a great day #:O)

Very nice lesson! You can point and shoot or you can visualize the shot in your mind for more dramtic effect...thanks for another handy lesson! Aloha~

I found in a rifle crack I did not believe in diopter. It added to my disbelief in determinants. Even the camera cannot save the ID. I grew!!
Enmos
Yeah, i see what you mean... youd better go for shorter or longer exposure here... Stunning display here though, still a magnificant capture !!! :o)
