@theluthier  what will be the best focal length for the camera in Arch viz scene ?

[smurfmier1985]

@malhomsi wow that’s a good question! Hadn’t thought about that yet..

With my ‘real’ camera I would pick my 50mm for close ups of certain details and my 35mm for a wide angle shot to get the whole room in the photo (while standing with my back against a wall to get the most in 😛). But you get some distortion with the wide angle lens and I don’t think Blender has a correction function for that like Lightroom has for instance? So I’m very curious what @theluthier would pick for a 3D scene, guess totally different 😬 Also I never really photographed interiors so what do I know? 😜

@smurfmier1985  thank u for ur answer 🙂  i m modeling my “blender corner ” at home and i’m using true world scale in my scene  , but i’m having hard time setting my camera angle and focal length ! i know Nothing about photography 🙁 

[smurfmier1985]

@malhomsi Cool idea!!

There are lots of videos on YouTube which can get you up to speed in no time 😀

A list of common settings:

Focal length

• 35 mm for wide angle shot, often used for outdoor/nature
• 50-60mm for portrets/characters, this comes closest to what the human eye sees
• Anything above is zoom

F-stop

• 1.8 gives extreme amount bokeh, soft edges of your subject, a lot of depth of field -> I usually find this too extreme, but it has its artistic purposes 
• 2.8 – 4 is what I usually use for portraits, sharper details but still lots of bokeh
• 4-8 is what I also use for close ups of objects
• Higher than this means sharper details, but also sharper backgrounds so less bokeh/depth of field , which I would use for stuff like nature scene etc.

Note that I am just an amateur photograph hobbyist, so I’m at no expert at all, not even close! These are just some values I’ve learned through observation and have come to like throughout the years. Hopefully they can give you a starting point.

This is s useful tip when it comes to architectural renders:

@gradyp I have an innate subconscious desire to dive into the pile of pumpkins in the last pic…

@dostovel Thanks Omar! Useful indeed.

I can’t offer better advice than @smurfmier1985 about camera settings! I’d bet she knows more about cameras / photography than I do.

Personally, I don’t go too crazy with camera focal lengths. I know from my wife’s photography interest that 50mm, 35mm, and 16mm (I think) are viable realworld camera lenses. So I typically jump between those and see what I like in Blender. Though I usually start out at 60mm as I’ve found to be my preference. I was taught in school that 35mm is equivalent to the human eye..

All that to say: I try to stick to values that have realworld standards but ultimate decide on artistic taste and what achieves my goals (like seeing the whole room vs dof-heavy focus on a particular object).

Very interesting tip from Chris Plush. I’d never considered the 2-point perspective thing for architecture 👌

Hmm…am i the only one wjho cant download the bathroom scene?

[Kent Trammell]

@arev Whoops I’m not sure what happened. Just fixed it.

[malhomsi]

@dostovel   very usefull  , thank u 

[Morten Fjellheim]

Just a few questions about the bathroomscene. Is it a really heavy scene cause cycles seems particularly slow, slower than in 2.79. And why does it feel like the hdri is shining trough my mesh when using eevee? Is there something wrong with hdri in 2.8?

[smurfmier1985]

@arev I’m not using the scene @theluthier provided, but in my scene I also experienced problems with the HDRI doing funky things in Eevee. They got fixed after I added light probes (irradiance & reflection cubemap) and baked the indirect lighting. Also I reccomend using a reflection plane light probe for the mirror to get better reflections there.

[Morten Fjellheim]

@smurfmier1985 I see, anyway i started anew in 2.79. The scene was running so sluggish in 2.8. Now in 2.79 its all good.
