Lights masterclass ! I'll need to lighten up to keep up with the doc...

Another lighthearted Poser exploration! I alight on my seat! I'm so bright my dad calls me "sun."

Let there be more light...

count me in ! (i am late, i had to take a trip for the job); of course cause the questiosn concern me :) i try to read and understand all, gimme some time to swallow it and continue if you still has things to reply/add to explanations.. i'll tell if the dumb me get it all right :)

Sorry, but this one is very difficult to answer. There are so many variables involved that I can not give you any specific recommendation for a "light set." The lighting depends on what effect you are trying to produce. For an outside picture, one Infinite white light (with shadows) to simulate the sun. Use strong shadows for a sunny day and subdued shadows for a cloudy day. The position of the main light would depend on the time of day. Use additional Infinite (or spot) white lights (without shadows) to fill in darker areas as required depending on what is in the scene. Avoid using strong colors for lighting unless it produces the effect that you want. Use white and shades of grey which is just white with reduced intensity. For the answer to your question about spots and Infinite, you might find some useful information in [ THIS tutorial.](http://www.renderosity.com/messages.ez?ForumID=12356&Form.ShowMessage=1633161) cheers, dr geep ;=]

thanx, i think i got most of the questions in myhead now.. will tell you soon if i still miss something.. about the lights+color vs/ texture skin, why some "professionnal" item sin RMP have a very greenish look (on photorealistic textures such as steffy zz) ? what this tone for ? and how it is meant to be used then, i mean what kind of ligthing such "green looking photorealstic" textures do require ? something to do with the numeri csum of colos like in your intensity explanation ?

hmm about the page 2, i saw nice different examples but can you explain/detail each of them ? so i can figure out some chromatic rules of light colors and posiions to achieve same kind of effects (and others you may not have displayed as example yet) ?

Hi Yohu,

Greenish look?

Well, different people may see the same color differently.

Maybe it's "bluish-green" to one person and "greenish-blue" to someone else.

Add to that the fact that no two color monitors will look exactly alike.

People adjust their monitors so that it looks good to them. Some like high contrast, others like really bright colors.

The gamma adjustment on a monitor will, also, affect the way a picture appears.

The red, green, and blue intensity can be modified on a monitor, also.

Put all these factors together and I can't tell you why a picture looks a certain way on your particular monitor.

Ok?

Different examples?

The best way to see different examples is to use the light sets that Poser already has in the Lights Library.

Load one and then look at the effect and the color and position of each light.

Did you know ... You can "Alt-click" on the light (the little tiny colored circle) in the Light Controls display to quickly turn any light ON or OFF.

Try different combinations.

Try changing each one to a spotlight.
(remember to "point at" something to make things easier)
("point at" the GROUND - that's an easy one)

Try everything you can think of to change to get different effects ... then, try something else. ;=]

Remember, what looks good to you may not look good to someone else.

Unless you need to earn your living as a professional photographer and you might starve if you don't "get-the-colors-right," .... don't worry about it. ;=]

Just have fun ... and make pretty pics.

Ok?

cheers,

well about screens i knew abotu that.. usualy on computer screesn there are only two "standardized" presets, one that makes a very grey/washed look, and another more red/warm; some faulty monitors or video cards gives out green look. i have the luck to have a screen (since very few weeks) that i can set as i want, with precision, and i usually put all colors and gammas to equal settings, so i know there won't be "mistakes" when i work on a texture or watch one... but you are right, this is an issue an artist or a picture/texture maker cannot have controlon (means other's settings). thanx for the "alt click" to turn a light off, i did not know this oen and i can remember too many moments when it could have been useful... ---- i guess i got most of the content of this special "just for me" class, thanx Dr. geep. now i remember others questions STILL aboutlight, whiel we did not move yet to anotehr topic: it was about lights and relation with highlights. (off topic: do you plan a tutorial on material color settings, such as reflective color, ambient one, highlight and such ?) and moe about it, it was how lights are handled in the very specific cartoon mdoe that is often used nowadays. I mean i saw BLACK lights havinf effect on shadows on areas still lit by a direct white one, so what can be the used of "dark" lights, and how the lights behave regarding the cartoon mode ? i hope i am not too pesky and curious a student for you, you must be exhausted with my questions... (btw you already answered abotu lights and sketch design, i hope you'll release a sketch making preset tutorial to explan the whole thing, sketch designer seems very complex a tool in itself)

Hi Riddokun, Doc did make a tutorial on the Sketch Designer, and the Materials dialog box. He may not have gotten around to re-posting it yet. Give him time. By the way, there are many many free light sets available at Runtime DNA. Here's the URL in this text. You'll have to sign up to be a member, don't worry its free.Download those lights and play with them. I don't think a "black" light has any effect on a render since it casts no light. Its just been turned off. Good luck!

Hi Riddokun,
