Why, thank you very much Ms Rhiadra

There IS a  difference. The simple answer is that the default viewer "camera" view gives you a bigger nose than usual. I't's like looking at a mirror through a glass globe: it is distorted. When you "zoom" you are removing that distortion and seeing the true shape (it's like flattening the glass sphere - the more you zoom, the flatter the sphere, the less distortion happening).

It's called Lens Distortion, based on how much of the lens is being used (the curvature of the lens) - here is a "lay-persons" explanation: https://expertphotography.com/what-is-lens-distortion/

The technical description is this: you're not really "zooming" - the lens is curved, the picture gets more distorted the farther toward the edges because of this curvature. When you "zoom", what you are really doing is "blowing up" the picture to eliminate the distorted edges. Think of it as "cropping" the picture in-camera. Since the size of the vire cannot change, the picture is "blown-up" to a larger scale. This appears to us as "zooming in".  AND all I've said is vice-versa when "zooming" out  (using more of the lens edge to create exaggerated distortion, when desired).

Yes - exactly right, Alyona Su - it's the 'big-nosed-fish-eyed effect' without ctrl + 0 and 8.

OMG. Of course. WHY DID THIS NOT OCCUR TO ME BEFORE????? That totally makes sense!!! THANK YOU.

 

Yes, but here's what is confusing me. This is what Wildmist says about focal length:

In practice, I'm still confused about the actual difference between the effects produced by field of view and focal length in FS.

Had to actually pull up FS Phototools to look at it before I replied last night because my fingers and eyes are so used to doing what they do to take pics, but the trade-off is that I suck so badly at trying to explain what does what and why - sorry, chickadee!

Well, since I don't seem to be capable of keeping: 1. my big mouth shut and: 2. my promise from earlier post to not post offtopic stuff in this thread - I'm at it again...

Taking the risk of being labelled as an annoying nitpicking something, I must comment on the above and say that the "bigger nose"  is due to Perspective Distortion, not Lens Distortion - as mentioned halfway down in the linked article above...

Lens distortion is more or less constant regardless of how far from or close to the object you are taking a picture of, perspective distortion varies with the distance.
Advanced photo software has the lens distortion of different model/brand lenses build in so that you can remove lens distortion made by a specific lens more or less automatic - not that easy to correct perspective distortion...

Pure Windlight and Firestorm lighting,  otherwise cropped only! It's nice when it all comes together inworld... 

Great pic, and I especially love the warm sunlight and shadow on the wall and bookshelf!

I need to play with Windlight a lot more. When I shoot in the morning or evening, I find that the entire scene tends to get saturated in yellows and oranges. This is much more selective, and really lovely!

   So this... Started with Cat suggesting I do a Christmas shot. And uh... Well, things happened. My creative process is occasionally a bit awkward and quite thoroughly twisted.

Ho ho ho????

This is terrifyingly beautiful. Or beautifully terrifying! Either way, I really enjoy the characteristic aesthetic you use in these shots.

(I need to reread the The Picture of Dorian Gray again soon. Can't imagine why I thought of that . . .)

Yes, yes! The wonderful thing about Second Life viewer (all of them) is that the Lindens created it to literally mimic true camera and lens physical properties.

There are virtually no photo tools in the SL viewer, are there? If there are, I wasn't able to find them!

(In real life those two affect the DOF too. f-number is obvious naturally, but longer lens length means that the DOF is narrower than in shorter length lens with the same f-number setting.)

This makes a lot of sense: in RL, then, you can set the f-number and then further adjust the DOF without changing it.

I'll have to experiment more with the photo tools, I think, to get a clearer sense of how these two might be adjusted independently to produce different kinds of effects and exposure.

But tomorrow. Right now my head is definitely hurting a little . . .

 but this is a place for beautiful pictures of lovely avatars, not long and winding stuff about optics, 3D rendering and all that jazz :D - 

Totally agree... I think I helped start the tips/tech rants that have seemed to dominate the thread as of late. Sorry. Fascinating though, I’ve learned a lot and way cool stuff - but I think a lot of us have kind of veered off topic for this thread. To quote Angelina “More pictures of lovely avatars please”. 🧚‍♂️

Sunset in SL turned much better when viewed in Ultra ... couldn't resist uploading a screenshot.

 The addition of a face light would have made this picture pop. While I almost never use them, They can be a great addition when standing in front of a sunset.

I use the term "lens distortion" because all photographic distortion is colloquially called "lens distortion". I bring this up because most specific terms used here and everywhere are misnomers in most cases, for example, as LL love to harp: it's a "region", not a "sim" and if we want to get specific on correct terms: these are not and never will be "photographs" - they are screenshots, though Linden Lab calls them "snapshots"

"Phototools" are in every browser, but scattered through ambiguous areas throughout menus and keyboard commands. What "Phototools" in Firestorm does is to put them all in a single box for quick access.

That's what makes your photos so great, though!!  You take things in a COMPLETELY different direction than I could ever think of!  That's what I love about it!!
