..for those camera problems use "show camera" and move camera, target and doll manually.
You can even make an "aligned dimension" from point (camera) to point (target) to know the Focal distance.

... now you need to add your emitters.

I tried to reproduce Thomas's rendering of my Medieval Knot illustration, but it came out dark and flat, why?


ENGINE
Render Time: 10 minutes
Sampling Level: 25
Number of Threads: 25
Max Bounces: 6 2 3

Number of threads 25?? Why? If you have dual xeon, you may have eg. 4 threads, not 25..

[tom]

wake up from LAN option?

[Thomas An.]

Medieval Knot was in CENTIMETERS, not the glorified METERS. (I'm considering changing it to METERS)

Why ?

[iker]

Cedric is not like that, is the same ( if your object is 1 meter it fits in a square of the grid when your Units are meters, but if your object is 1 meter it will fit in 100 squares of the grid if your units are cms but is always the same size), the point is that if the focus distance of your camera is 20 cms away , when you convert your Units to meters is going to be 20 meters away, and there's the diference, you can choose between scale your geometry or not when you convert your Units but the camera is always converted ( you can't choose when you convert Units to keep same distance for the target of the camera or not )

sorry for my bad english

Hello,

I did a test with skylight and changed units. Here are the results:
Location Madrid, August 1st 10:00 AM. SS=0.25; fs=128
Camera 50mm
Render Time 10 minutes. Same diffuse material
It would be really nice if we could input the shutterspeed like on a real camera : 1/8s, 1/4s, 1/2s, 1s, 2s etc. The input of longer ss is now confusing in my opinion

Units are kilometers

units are meters

units are centimeters

units are millimeters


the micron rendering turned black.

Alexandre13 , fStop 128 for your tests?

[Thomas An.]

Alexandre,

About shutterspeed: it is shutter Clicks per second like rpm is revolutions per minute (hense the word "speed")

So 125 reads: "125 shutterclicks per second"
Higher number=higher speed.

I think the cameras are confusing and counterintuitive and Maxwell is good

Alexandre,

This test is incorect.
When you changed the unit from 1meter to 1cm it means that you reduced your model by 100 times fold. You need to keep the size constant.

You need to change from 1meter to 100cm.

Thomas,

I started to model in mm, then I changed the units to cm, m, km and mu,
but when Rhino asks me to scale I answer NO which scales the size of the model up to the next unit. 1cm becomes 1m or 100cm etc...
Is the test considered correct now
If you change units and answer YES then it will scale down.

The F Stop is 128, I wanted to achieve a very high DOF, thats why the exposure time has to be so long.

[Thomas An.]

...but when Rhino asks me to scale I answer NO

You should say "YES" to that prompt.
Rhino is scaling it so as to keep it the same size under the new unit system.

...maybe he's doing a diferent test

[iker]

ginosso, I can't understand your test

Thomas you ruuule! hehehe...
