WIP and shift lens test (update p.2)

Sure. I'll post some screen grabs when I'm finished.

Basically, without the shift lens, you wouldn't see the feet of the table and you would see a lot more uninteresting ceiling.
In order to see the whole table without the shift lens, I would have either to lower the camera (inconvenient: very low POV with the table hiding everything that's behind it) or rotate it so that it faces downwards (inconvenients: the nice vertical lines in the image would no longer be straight but "bent" towards the bottom of the image due to the perspective).

You could choose a narrow resolution (nx3n) and do a crop.

Not sure what you mean?

Leave the camera as is and instead of using a (let's say) 800x600 do a 800x 1200 resolution, then crop the surplus...

Yes, that would do pretty much the same thing pixie.

Great image Bertrand !

Shifting camera is a nice improvement too in addition to displacement, so many new things in this release, I was out for a while ... I may have missed xmas

Some minor crits already mentioned, so just waiting for the final result, for sure it will be another master piece.

That's right but that would be very inefficient, wouldn't it? Especially if you render at 2000x2000. Who'd want to waste this precious render time?

enricocerica
Thanks man. I've tweaked a few things. Working on a night shot right now. 64-bit is really coming in handy.

No doubt about that, the only thing going for it would be that it would bring more flexibility in the sense that you could crop from a render instead of opengl window.

You could also combine an odd resolution with a region render for the spot you need, to not waste CPU.

Or just use tilt/shift

BbB · Post by **BbB** » Thu Jun 05, 2008 9:53 am

With region render it would make sense, yes.

I thought it would still waste ram...

Oh, thx for the explanation Bertrand, it's crystal clear for me now.

(so no need to post quick renders with and without shift lens unless someone else was interested.)

Errr....I would love to see the before and after, and the values used.
(if possible)

Sorry guys. Heavy day at work. I'll post viewfinder grabs to show the difference as soon as I get a minute.
Only thing I can show is a final render of that particular scene, but only because it was cooking when I was away (about 24 hours).
If you look closely, you'll see the time stamp at the bottom. Which tells you this was downsampled by 50%.
I did more work on it than it may appear at first, but sadly it hardly shows (different fabric texture, objects on the table, redone the table mesh, which was a mess, bits and pieces added here and there).
The scene is now "night ready" and these night shots will come next.

HOLY SHIT

To the gallery, now!

BbB, I have no way of expressing how fantastic your renders are.
