    OK a VR quickie

    watch on youtube in HTML5 or Chrome

    and for those underwhelmed by this new addition, you need Horo and David Brinnen to teach you about making your own HDRi images for IBL.

    render two exposure settings use Picturenaut and shove it on your iray dome or uberenvironment sphere and you need never be bogged down by big sets and lighting your characters again

    Would it not work to use a Canvas to genrate a single-exposure .exr?

    possibly, I have found it complicated using exr but then I do not have photoshop, Blender compositor was my only solution for even opening that format, I work with tiff usually in Picturenaut.

    But for those with photoshop it prob is better and I have not tried an exr on the iray dome yet but as D|S does read it it should indeed work.

    This is great news.  Being able to create 360 images for VR, within DAZ, using a single camera, is going to be a lot of fun.  Get your Google Cardboard glasses ready!

    What?

    Picturenaut is not suitable for HDRIs to be used with nVidia iRay. The color-bit and EV ranges are way too small.

    ah well I am no expert anyway, just thought you needed two images with different exposures to make a HDR image as read it online, I do image based lighting just using one ordinary 360 image mostly anyway and to my untrained eyes it looks ok too.

    Please explain?

    What about Fusion free and Luminance HDR? Fusion has a 32bit free version and Luminance HDR has both32 and64bit for free.

    ??? I've managed to generate an HDR image with near 20EVs in picturenaut and it was moonlight not even sunlight. I've used it to rescale HDRIs with 24EVs with no changes to the EVs and image quality.

    How did you do?

    I started with an 24EV (sunny sky) and picturenaut automatically reduced it below 17EV and 24bit only. As an outcome the lighting was corresponding to overcast.

    In the case of the already made HDRI I literally just loaded the .hdr and resized it. In the HDRI I made, I loaded the raw files from my camera and fiddled with the settings a bit. What did you do?

  • Silver DolphinSilver Dolphin Posts: 1,617

    You need a decent tripod with picturenaut and raw photo format. that way your 3 exposures are spot on and you can get HDRI image you want from your digital camera.

  • AndySAndyS Posts: 1,438

    Ah RAW, OK.

    There isn't any chance to do it based on jpg in a sufficient kind?

  • darren_dd9be07039darren_dd9be07039 Posts: 59

    Rendered out an image as a jpg to same dimensions etc as some non hdr jpg images I already have for using as environment sphere backgrounds. When I try to render an image the background is white. I've tried adjusting luminance etc, but no matter what I do the actual image doesn't show. I know I must be missing something

    I tested with the jpg versions of the raw images I used to generate my HDRI with 20EVs and got an HDRI with 18 EVs. Both of these were with 7 different exposures not 3 however.

    I did some tests using only 3 exposures:

    For raw files: Using the middle and 2nd shortest and longest exposures I got 17EVs, so a bit less than 7 jpgs > therefore more images can be more useful than raw formats. Using the mid and extreme exposures I actually got slightly higher 21EV spread and no difference in image quality as far as I can tell, so that's weird and warrants some more experimentation.

    For Jpg files: Using the middle and 2nd shortest and longest exposures I got 16EVs and a bit of color issues, with the mid and extreme exposures I got 21EVs, but the color was extremely messed up. Non-usable messed up, in fact.

     

    Again all of these are using the same set of images of my yard at night with a very bright moon

     

    Another important thing to note, jpgs are often less likely to store exif data (ie information about the shutter speed and such) which is info you need to get accurate HDRIs, (technically you could maybe manually fill it in, but...)

    Does D|S accept a 32-bit JPEG? (Messed up colors suggest not.) 

    I ask because you'd be hard-pressed to get 21 EVs out of an 8-bit file. Something in the software is lying if it says otherwise.

    Thats not in DS thats the hdri generated by jpgs in Picturenaut. jpgs are only ever 8-bit however if you combine 7 of them you can get at least 18EVs per my experiments

    There are 32-bit JPEGs. It's not a standard file format. I've only ever seen it with some imported cameras. The 12-bit JPEG format, which is formally specified, is used in some cameras, but won't support 18 EVs.

    I'm not understanding the output file you're producing. Technically, you can make an HDRi with any 8-bit image file if you "stack" them and produce a 32-bit output with the expanded histogram. What output image format does your software create?

    This is what I'm doing. taking multiple images at different exposures and combining them to make a 32bit image in picturenaut > the method one uses to make a environment map for 3d software.

    As mentioned I am combining multiple images to get the 18 and higher EVs I've been using raw files, but someone asked about jpgs so I tested with jpgs.

     

    I'm saving out .hdr or .exr

    I've used DS to create HDRI from a 32-bit EXR:

    Can you show me where is the parameter for 360" camera?
