The "chicken versus the egg" order of the photographers subject and lighting let's put aside!
I say that "One starts with lighting!" as a dogma since without that there is nothing coming into the camera.
One step back first.
The idea, the first instance is to
know how the controls work to get the correct exposure. So one must master the basic knoweldge that a given amount of light sufficient to get and image with a range of shading requires a suitable combination of
- Film/Sensor sensitivity
- size of the shutter aperture
- time shutter will be open to allow light to reach film/sensor
One needs to be totally familiar with decreasing one factor and making up for it with a change in another to make up for the particular change.
So
find a reference on that and let us know you know it. Don't bother to go further without mastering this as you will have no way of controlling what you do.
So when you find the best reference for this. Add that in your next post for others who'll follow your footsteps and read this as a requirement, LOL
We start with lighting was because in your picture, just several leaves are kit against a dark uninteresting background. There's
insufficient light distributed in the image to allow exploration. Let's put aside ideas of art, for the moment. I really don't care that the subject happens to have potential. The issue is that here we have not yet gotten the light we want!
When you shoot indoors with your studio lights you can distribute the the exposure over and around your subject to make it both sufficient for the particular camera setting (of ISO, shutter aperture and shutter speed) and make it, unique, interesting and compelling.
When doing your river shots, you still have the same requirements, no matter where you choose to point your camera! It's far easier when you do it right since you don't have to mess around with gear!
But what did you do when you took that picture? You saw the bright rust colored leaves! Then you took the picture! However, there were no long light beams coming throught the trees playing on the entire scene and then highlighting the leaves you like.
So while you have
some light, it's not
the light.
Now one can solve this somewhat in an editing program like photoshop. Take zones in the picture and lightening then with different patterns as if it was done right. Yes, it can be done, sort of and might even be nice. However it wont be great. Why not?
We are too educated and spoiled rotten, that's what we are up against. I say "Good enough!" Isn't!"
We all have had our senses educated by great shots of in woods with light filtered through trees as the sun rises, mist still hugging the ground. Long shadows wrap streaks of light drawing over everyting, awaking beauty.
So we cannot just pop into the woods any time we want, point at a bright leaf and expect to get anything special. How can we if there's no light anywhere else?
Even if the leaves are lit, angled light creates dimension and reveal texture which wil make your leaves real.
Now if you
must take pictures at the time, then you can be very sacriligious and do what macro photographers do when they don't fear heaven! They use flash!!
Those perfect pictures of spider webs and ants herding aphids are generally the products of careful stage managing, hopefully without crushing native plants or other damage.
I'd not start the hard way, trying to light the woods properly. Rather choose a well lit subject or come back when it
is well lit!
For my ambitious photography I don't have a camera, just scout and come up with a plan and then come back with the right lens at the right time.
So in your choice area, by your river, when I say, "The subject is not important and it doesn't have to be in focus!", I really mean it.
First we hunt the light (unless you shoot macro and bring your own).
Then we hunt for the real subject and we work out how the subject and light will be best recorded.
Since you do like the leaf, I'd try to go there early in the morning and study what happens. Bring your family and a picnic perhaps and just
see where the light goes and look at your watch and make notes.
The nice thing is that you don't need to bribe or pay for a model! No lights to lug around. But one does have to shop for light!
Then you'll find your subject! Even then, the light will inform you how and from which position and time you will trip the shuttter.
