View Full Version : Post here your HDRI's

07 July 2003, 12:00 PM
Since HDRI is becoming more and more popular I felt something was missing....a free HDRI thread. Just like the texture thread and the tutorials thread.

Please post anything that has to do with HDRI here.


Here are some links to free lightprobe galleries:

9 complete HDR's with different mappings:

63 Sky HDR's, good if you want to use groundplanes in your image or just a sky:

And here is a very good Probe gallery that also has the source files so you can compare your own method with theirs:

Here are some very good HDRI's that are not free but very good:


Here are some links I found very usefull for creating HDRI images:

How to get rid of the photographer:

Tweaking your HDR's:

Paul Debevec's free HDRShop:

Here is a tutorial on how to import your image sequence and some tips and tricks are mentioned here that aren't on the HDR shop site. *sigh*...if I only knew this site BEFORE I went to try hdr out...

Here is a tutorials on how to use hdr's in Cinema 4d (this was written before the 8.1 upgrade but still is of great help):

This tutorial perfectly explains you how to composite with HDRI (just like BLochi's HDRI challenge)

And here is a tutorial about how to create panorama's from a mirrored ball (still the preffered method)


I also made my own HDRI this afternoon with my christmass ball, HDR Shop and photo's taken at multiple exposures. It took a couple of hours of tweaking before I got this result. You can download the scene file here (bumpercar included :p ) :

edit: just reuploaded a newer version of my backyard hdri. Now has a seamless 360 panorama and a good HDR file. Have fun!

Hi all,

I decided to give something back to the community that helped me so much,
I put all my favourite lightingenvironments in here.
(2.54mb. Cinema 4d 8.5 needed, if you like to use it commercially please mail me.)

The Radiosity showroom has my supra paint shader in it and the backyard has a procedural skinshader :).

Have fun!

Truly a beginner, but I put together this review at the ArchiCAD-TALK web site. ArchiCAD-TALK is a web site supported by GraphiSoft the makers of ArchiCAD - Architectural Software.

not especially HDRI-s, but a whole lot of nice parnoramas for use for scene reflections etc

Simply, whats a HDR or HDRI???

02 February 2005, 10:51 AM
gr8fxtznr: HDRI = high dynamic range image. i must admint i'm not totally aware of the technical side of this thing but the way i see it is something like the comparison between film photography and digital photography - figuratively HDRI and JPEG respectively. Or you can also compare digital RAW or digital JPEG. that's almost what HDRI is about - a larger dynamic range. It contains more information about existing light and the amount of it. so with an HDRI you can lighten the whole image and still not burning out the highlights. That's what you can achieve in film photography or with digital raw. the HDRI image doesn't have what a reglar JPEG has (simple RGB values), what it has is the tone of each pixel and a floating point number that indicates it's brightness. And with that control over the brightness you can achieve much more realistic renders using HDRI spherical maps as your default light source.

so anybody who finds something off in my post, feel free to correct me. it is just how i see the whole HDRI phenomena:)

mihkeltt is pretty right about hdri meaning.
If you want to dig a little more inside exact descriptive of what is and how to use hdri here's an interesting link with fully comprehensive examples.

So, how do you take HDRI images?
i'm assuming it takes a pretty expensive camera.
I have a digital camera, it's not HIGH end, but it's definitely not just some plain ol' camera.
a little explanation though

03 March 2005, 12:38 PM
a standard camera will do fine, though the higher resolution the better the hdr will be.
Then you need a chrome like sphere such as this one (diameter is approx. 12 cm):

i ordered this one from my father's factory. It is full aluminium chemically hard chromed, and we did a fillet at the base to be able to screw it on a standard photo tripod

Now you can shoot it on location. Put the sphere where your 3D object is supposed to be, like this you'll get the exact environment that will surround you object. Keep in mind to get the horizon really centered on the sphere (such as your 3D object would "see" it).

Then, if your 3D package doesn't provide an hdr processing tool (such as cinema4D advanced render module), you will need hdr shop software (only PC).
This link will explain exactly how many images (according to your camera abilities) you will need for your hdr to be perfect as well as how to use HDR SHOP software:

link to HDR shop tutorial (

Once you got your unwrapped HDR image, in your 3D package, put it on the luminance channel of a texture, put that texture on a sphere surrounding your scene (or a sky object if your 3D package provides it), set radiosity on, render your scene, and voila.

Hope this short explanation will be of some help.

03 March 2005, 05:53 PM
hmm, interesting. That wasn't exactly the type of response I was expecting. but THANK you!
your link is broken though, could you post an updated one perhaps?
thanks again!!

Compositing HDRI

04 April 2006, 03:32 AM
I tried to make HDRI's myself and all looked mushy. So I tried a different approach. When my hightech mirrored ball highres camera hdri attempt failed I thought I might go as lowtech as possible. So... I loaded PS and created a black 2048x2048 background. Then I created a near-black circle. Just so I could see where it is. Really dark. Then I imagined how a spherical projection might look like and painted a few lights onto it with a smooth and not a hard border. Then I saved that versoin and two others. The other two were adjusted for intensity. One close to zero and the other one so it looked way over exposed. Then I used the very cool prog from ( to plop them together. The poor thing created a .hdr. AND it works like a charm and beats anything I tried manually with so much effort. I had to laugh about myself. The only thing.... of course.. it only can be used as background when you are after something abstract. Here is the file if you like to have alook yourself. I am sure I could also use MSPaint for that. No joke!
Here is the test hdri ( check it out. You can paint your own environments. Of course, nice and highres real world hdri are tough to beat. But this is cheaper than those expensive studio hdri's. Let me know if you had some fun with it 8-). The Background in my test render is the testhdr in this case. I had to set the exposure up to an f factor of 1.5 or the scene would have been to dark with that crude hdr. I was truly surprised about the result of the experiment. Better than expected.


PS:Render in XSI and no lights on except for that single hdri.

PPS: The gradients which make this pic look rather sucky are the result of the compression. They are NOT in the originals.

Hi guys,
I tried to made my own hdri image, but I have question, I hope somebody will know the answer.. (I am used HDR Shop) I opened the assemble hdr image from ldr sequence window. I impoerted everything than I pressed the the button "calculate" under the calculate scale incrementstitle. After that I got that error message what is shown below. This means I did something wrong while I took the pictures?

Actually, RAW image files are still only 16bit and therefore still suffer from clipping that is inherent with all digital images besides HDR or scanned film.

What RAW does is to present you with a minimally processed digital image that represents the image that was actually passed over the image sensor of the digital camera.
It's alot more flexible than a jpeg or tiff file because it hasn't been converted to a traditional RGB image yet.
What you get is the mosaic image data as seen by the camera, no compression, very little clipping, and RAW actually has alot more data to work with.
It's direct benefits are being able to change the lighting model of the image, control and manipulate white balance, color temperature, contrast, and highlight/shadow values.

With HDRI, you are getting an image that can represent the dynamic range that's visible to the human eye.
Since it's values are 32bit in nature, you get much more variations of the light levels.
Your highlights aren't blown out so you can retain detail in them, and your shadow points aren't clipped so you can see detail in them also.

A regular digital image has say, 11-13 stops of exposure, an HDRI has maybe 18-26 stops, and a film image can have up to maybe 28 stops(give or take).
From a math perspective, your luminance values are represented in 32bit float mode.
Which means there are alot of 'in-between' values that are visible in the image that would automatically be clipped if those values were restricted to what's mathematically possible using an 8 or 16bit image.
It's somewhat similar to how 64bit computing architecture can address more memory than 32bit.
This makes the digital image close to what is possible with traditional film.
Film isn't math based, it's light sensitive material so it isn't subject to math values.
Film has what's called a highlight shoulder, which is a curve where the light levels subtly transition into each other.
Digital images don't have that. They either have certain values or they don't.
When you create an HDRI image, you take a series of bracketed exposure images that are a certain number of EV's(exposure values) apart.
You end up with over-exposed and under-exposed images that you layer and adjust blending modes so that each of the exposures transition more subtly into each other, which adequately simulates the 'highlight shoulder' of a traditional film image.

Just thought I'd throw this into the conversation since people were asking what HDRI is, and some of the explanations were vague.
I do a bit of photography and I've researched this subject extensively.
There's a technique in photography called tone mapping that generates an HDR image, but it isnt 'a light probe or cross probe but more of a half assed layered image with a few exposures blended together.

Some may have seen this, but maybe not:

I announce my first HDRI pack for Cinema 4D R12.

The files are very large grayscale HDR -files which can be used to build a studio
reflections and lighting for fast rendering. Image files are in 6K
resolution and have good amount of flexible resolution
for blurring, exposure etc.
These are very useful HDRI files which can be used in reflections
and global illumination studio environments.
You can use these also only for reflection without
global illumination activated.

There´s a cinema 4d file for R12 which is
a studio scene. This scene comes with ready floor and
light setup and 10 cinema 4d materials with HDR files.

You can download first hdr for free in 1/2 resolution
of 3000px.
