Questions RE: "flat lightening"

[o hey tyler]

Nope! All photos are 2-D representations of the real 3-D world.

A little off topic, but what we're seeing is light, or energy. Just an image in our brain. Photons are mass-less, so I'm not sure how many dimensions humans can perceive. We move in three dimensions.

Thanks again for your help. I may not own a proper flash, but I have learned something. If you don't mind, I'd like to judge the "pointfulness" of my own threads, thank you very much But lets not get another argue thread. Have a nice evening/day depending on your time zone

Well, it is kind of important for one to understand that photographs are two-dimensional, if you are going to be a photographer. They are the merging of an infinite number of layers in a three dimensional world parallel to the image sensor being compressed into two dimensions. A photo is flat.

Not trying to argue, just sayin'.

No worries, we're all different Though this thread might be premature, I like to understand terminology I might come across elsewhere. And having an idea of this helps me recognise limitiations of pop up flash and not having a flash at all. I also read up on other aspects of photography, I might be able to transfer the knowledge to what I'm doing right now.

Well, I won't say I'm convinced a printed image is 3D, the surface is rough. The light it reflects, what we call the picture, are photons at different wavelengths. Photons are mass-less waves (in this setting, at least).

 

[o hey tyler]

You're referring to the medium that the image is printed on, not the actual image. Digital photographs are two dimensional.

 

[Compaq]

The digital image stored on a computer is just programmed information, lots and lots of 1s and 0s. It's not anything physical.

You know what? It's a public forum, and my comment was directed to a topic you raised in the thread, "Of course, all photos are 3D". My further comments were directly related to the topic in your OP "Questions RE: "flat lightening".

Please, feel free to add me to your TPF provided Ignore List at any time.

Have I missed some insults here? I like you.

To be 3D, you must have the "Z" (zed) dimension. A print or a monitor has the X and Y dimensions (length and width) but each lack the Z dimension (depth). Where is the depth in a printed photo or the image displayed on your computer monitor? Your rationale for a photo to produce 3D is erred. With ingenious lighting, the 3D effect can be produced on a 2D medium, but it is an effect only.

 

[Compaq]

What you're talking about is the light reflected off of the medium, or light transmitted from the monitor. Those are photons, they are massless waves moving through 3D space. Photons exist, according to the current paradigm, but don't take up any space. The waves can move in all directions. A camera exists in 3D space, it's three dimensional, but photons are energy. What is that, then?

Impressive...

The spaces didn't hold. When I hit submit, it was an impressive diagram.

Let me try again.......


X _ (length)
Y / (width)
Z| (depth)

 

[Compaq]

Yeah, I got that

Still, erh, ..... call it a draw?

Naw, the thread is not pointless: the camera's on-board pop-up flash can be used as a source of fill-in lighting in many situations, like backlighting and strong sidelighting. The flash that sits in the hot shoe or the camera's own pop-up flash provides what is called on-axis fill lighting. One of the easiest situations to use it as a fill light exists when outdoors, with lots of natural sunlight coming from behind and off to one side of people. It's at such times that a bit of on-axis fill lighting can make pictures much,much better.

Maybe in YOUR "photos" - but most of us on here would never even THINK of using the on-camera flash for ANYTHING - in fact, my camera doesn't even HAVE one! Lol. So go take some more vacation snaps

Thanks!

Of course, all photos are 3D

Um, no they aren't, just query for the user name "Sabrina-O" on this forum.

How do you guys avoid flat light?

The best, most accurate way, is to start by reading the book I posted for you up above. When you read that, it'll all become clear and you'll be on your rooad to becoming a much better photographer. Creating "non-flat light" is simply this: Metering your lights with a ratio other than 1:1:1. That's really all it boils down to.

As in concrete examples, if you wouldn't mind.

Here is a good example of "non-flat" lighting - you can't get this in a mall! Look at the three-dimensionality created by the ratios of the lighting - it gives depth to the photo and adds drama - this is an example of "rembrandt lighting":
