    Default tired of getting the right settings

    hi all i am attaching a file that i am working on
    have read tuorials about vray sun, sky and physical camera everywhere on the net
    but once i try to use it in my scene i am not able to understand how to have good settings. either my scene turns yellow, or is it too bright and burning
    even my colors of materials get too tinted.

    i dont know how to keep good settings so that i have a nice day scene with not too yellow light but more of bluish whitish day scene

    please see the file here. sorry i couldnt upload it to cgarchitect because it was more than allowed limit

    lol@jakub

    what i meant was, dont feel obliged you have to use them or must use them. you dont. you can get, imo, better results and certainly more control without them. i only use the vray sky/sun if i'm in an uber lazy mood. and i rarely use the phys camera.

    and dont feel using the sky/sun is an advancement on 'conventional' methods either

    The thing about VRay PhysicalCamera, sky and Sun is that if you don't know a lot about photography techiniques, then you're in trouble. These are all about getting a good real-life picture, not CG, so you have to learn how to setup a real camera in order to work with them. To be honest, I really enjoy the ease of use the physical system offers, and use it relativelly often. Even for interiors, sometimes using them makes the whole process a lot faster and easier. Of course, you lack a bit of control over things (the sun acts like a sun and so on), but you get used to it.

    If you have read all the LWF tutorials, and also tried adjusting the brightnes of the sun/sky (depending on which version of vray, values below 0.1 or 0.07), also make sure your not double gamma adjusting, make sure your rendering unclamped images, and yes it helps to know about ISO & fStops & Shutter Exposures

    But even with a max camera, if you render floating point images you can still adjust the exposure later.

    Rick is right. I am not a photographer myself and I find (for now) the vray camera hard to manage. I personaly use a directiona light and attach it to a vraysky (veru cool feature) because I can have more control over it. If you want to use the vraysun and camera go for it, but don't get the feeling that if you don't you won't get nice results.
