so the PC is very weak, render 1 frame about 10-14 hours - 1920*1920px , 16/6

what's your pc? i want to compare with my weak pc)

no, camera still will be move a little when i push button.

i already tried it. i put camera on table and use continuous shooting option, pictures had a difference.

If you own photoshop, then it could be easily aligned. I'm not sure if photos still would be applicable for noise averaging, though. OTOH, pictures shot at base ISO and long shutter speed gives almost as good results as averaging from multiple shorter exposures.

i still need tripod if i want shoot something... not random shit at home.
i dont think i can merge photos with offsets

nevermind, for photography need get out of home (may be go on nature) and it need do, being not alone. (especially in my city). I dont have such opportunity.

most cameras I saw had autotimer that enabled sequences...

my old one, i didnt saw such option

atleast i can use my program for reduce noise from photo... if only i had tripod and remote for camera..

You can make bean bag at no cost and practically all cameras has self timer, so... there's nothing you can't do.

averaging images like this is exactly what happens internally. If you average 5 images with different seed, you will get the same image as if you would render for 5 times longer.

UNLESS....

you average images with gamma on. This is wrong and produces incorrect image (and I think that is what happened - your averaged image is darker). Then you will get biased results, but probably with less noise. This is very similar to vray subpixel mapping on.

I didn't notice it is darken...(maybe because it is day, maybe in dark room it will be most notable). I just save images form framebuffer, gamma in 2.2 as default, i not touch it for corona render
Anyway, i expected it, i wanted to render test image for 5 times longer, but you already explain all

Well, i just wanted to make something, fail it will be or not.

Txh for explanations Keymaster.

Work in Progress/Tests / Noise reduction by averaging pictures

« on: 2014-07-05, 11:33:38 »

Hi.

I did an experiment.

Digital noise seems never completely disappear from the picture.

I leave render at all night, but noise still be here. (it is not very bad, and i think it common for all unbiased renders)

After some time of rendering noise reduction becoming smaller and smaller.

Yesterday i found this article http://www.cambridgeincolour.com/tutorials/image-averaging-noise.htm

I wrote some program (i know it can be done in photoshop, but i like automatize processes)

I render 5 images (445 passes per image, approximately 40min on my phenom x6 with legacy corona) by BDPT engine, with different seed

and averaged them

There is result:
1) one of original image

2) 5 images mixed by averaging

OMG SilentPrayerCG,

where you find this? lol.

Your image is the some reference for our character...i remember from the agency or client did love this ads. Thanks for share.

I'm russian. :) I saw it on tv and in supermarkets.

I thought visual resemblance is just coincidence, lol)

There that first commercial with eng. subs.

by the way, i always thinking that old stump from this ad, is ripoff of ent (Treebeard, i thinks, his english name) from Lord of The Rings.

Sorry about that.
Nope i will not try to... only answering maru's question in upper caps out of curiosity. It seems that qr codes are only meant for flat surfaces because the way iis encripted. That one for example its a 21x21 matrix of dots.

I thought small bending will not affect on readability of qr code, i was wrong i think.

About the image i'm still trying to figure it out how do you did it. I didn't understand maru's comment about being volumetric ligth.

I used Corona Volumetric Material representing default absorption feature, without refraction and with emission parameter.

Absorbtion still not support maps, and i sliced medium body on 7 parts and used 7 different materials.

I greatly love the render you post. All those tiny (big) details in the glass, even the background color to give more feel to the bottle refractions. Nicely achieved.

Thx!

By the way  correct the word "denisty" for "density".

Omg... a type...
Thx for notice that. I showed picture to my friend many time and he didn't notice, i don't know why.

This looks pretty much like the pony from your avatar, only blurred.

Wow.. how you?... I thought, i blurred it to unrecognizable.
Ok, it was same picture, but i dont know why i put it here. It made sense only for me.
Then i started thinking, and i think and think and think. I'm was afraid misunderstanding and decided blur it. I had to just change image ._.

Now you will try guess what it was?(

...
I think, it was bad idea make all this easter egg stuff.

What about image?

+4 to render skill?

it isn't potion

Keymaster probably never suspected anyone will ever use the volumetric light material. ;)

When i tried it in that case, it gave me pretty nice result and i decided continue that idea.

I can't decipher the scratched writing.... QR code doesn't work... I WANT TO KNOW!

Nothing special in QR code. (and i dont know why it doesn't work in this image, thought cuz my shity china phone)
First i wanted make some easter egg, but, i don't know, i blured that image in code more.
I dont know, probably because my bad mood.
