I need tutorials to render characters best quality look like the images of Girl Next Door
Real

Tutorials for girl next door come with the girl next door :O)

ok but i don't have girl next door

You'll aslo need high quality textures of the kind that come with the girl next door, to get high qyuality renders.  Textures are half the battle of getting good renders.

ok thanks

 Another possibility is to go to Rdna  (runtimedna )   and have a look at their  "Render Studio"  for Poser. 
Costs $ but will give great results even if you don't understand a lot about the theory of lighting
AND will help you actually learn about lighting as well.

Comes with good tutes  and the forum for it is helpful people too.

Hello, what I can tell you so far is, that pictures like this can only be achieved when you take care about the following things:

1. lights: the poser default lights will hardly give you such achievments, you will need to build your own lights or if you are new to that buy some. I prefer IBL (image based lightening) and have already seen plenty of good looking stuff here on Rendero which seems to have a good quality.

2. skin and shaders: A high resolution texture without shaders will not give you good results. You can buy characters which already have shaders (as most of them have today) or buy add on scripts like the vendor face_off has to shade your skin by yourself.  

3. render settings: what you can achieve depends MUCH on your hardware. You can't expect to render a large image in high quality when your computer is too slow etc. If you are a beginner I would hint you to try to raise your render settings and try them out until you are satisfied. 

I have never used things like render studio. Actually Poser has everything you need (render-wise) to produce images like that. 

I hope I could help you, if you have more questions, just ask.  

ok thanks
