Photographic exposure vs Logarithmic

Hi,

 

I was wondering what you guys' preference is between the two, for both interior and exterior scenes.

 

A friend of mine told me that Mr photographic exposure should be used for outside only, is he right or wrong?

 

In that case, is it ok to use Mr Photographic with standard lights, in say, a fairly closed room?

mr photographic all the way

 

your friend is sadly mistaken, it works fantastically for interiors. Only thing to remeamber is to try the unitless physical scale, and set your own according to the types of lights being used. As a recomended practice use the photometric lights and or the mrsun and sky system

Interesting stuff about the physical scale...

 

I've been using the exposure (EV) to help brighten up my scenes but never really played around with the physical scale yet. It's currently on physical units (default).

 

Bring the unitless number (now at 1500) up or down would also be a tool to brighten/darken the scene?

Thanks, I'll try this out too.

 

By the way, has anyone purchased the mental bout max videos?

 

Great stuff it seems...I'm wondering though (and if Brian Brandley could chime in that would be great):

 

Since I'm a max 2008 user, which of the "interior lighting setup" contained in "how to series" should I purchase?

 

Would it be redundant to purchase the M2, M3 and M4 in addition to the M7 and M8?

Basically by using unitless it is possible to specify a physical scale ala log exposure.

 

I must admit I dont fully understand physical scale, some days it all makes sence others not so much :rolleyes:

 

For exteriors I use cdm2 and for interiors unitless

Thanks Brian!

 

That's what I thought. The max 9 videos seem to cover a bit more ground, which is always useful.

 

Great site for us mental ray users. :)

 

 

Hi Khaled,

 

Happy to chime in if asked. :D

 

In essence all of them are relevant. The earlier videos go

more in depth on a few things such as Photon set up and

the daylight system, but also cover some non lighting material.

 

The Max 2008 ones bring some of the workflow upto date

using the improved toolset in Max 2008/09 such as the

Sky Portals.

 

Hope that helps a little, please feel free to PM or email

me if you need any extra help.

 

regards

Bri

Hi,

 

I have ALL of Bri's videos. :)

Well, he just released 2 new ones and I haven't gotten paid yet.

 

The How To series lays down some good foundation.

 

There's an mrSun tutorial that I got a few weeks ago but haven't watched yet.

 

Get 'em all! They're great value for money.

By the way, I quickly together a scene with mr sun/sky, and photographic exposure at default settings. 2 light portals at low intensity on the window and lightwell above sinks. (a bit of AO too)

 

I like what I see from this combination. I think it will work well for my projects.

 

FG at low setting and GI samples at 5000, 2500 and 250000.

 

PS: Please overlook the obvious quirky details...like the window handles, lights... and scale issues on certains elements. :D

Well the exposure is dead on. I'm trying to figure out how the corner condition of the niche above the sink is built :) Aside from the stuff you mentioned and the UVW maps on some of the wood (and I think a wall base would be appropriate here, and the plumbing probably wants to be next to the wall), you've got this thing down.
