No lie. Heh -- I just noticed the vapor trail. Cool.

Was browsing dpreview and found the thread discussing user experience with Rhinocam. http://www.dpreview.com/forums/thread/3447014

From a cursory reading, this appears to be a good product for masochists. Here's one typical problem

2) Nothing I have tried has resulted in the pictures taken with the RhinoCam being pleasing. Even though I am using a manually set exposure and white balance off a grey card with all of the shots the colors on the RhinoCam shots are awful and the exposure/dynamic range is also off. I have no idea why this is and I'm willing to chalk it up to user error but for me the RhinoCam photos definitely look worse despite their higher resolution.


Color in an ortho stitch made by shifting a camera behind a lens is a royal pain. It is caused by angular differences in the sensor color sensitivity. If you stitch without color correction, you get a combination of a "bullseye" radial color shift, typically getting progressively more magenta as you move away from the image center, and an an "Italian flag" color bias, green or blue on one side of the image, red or magenta on the other.

A stitching program that is smart enough to only look for color shifts in the overlapping areas of the image will conclude that the image doesn't have any color differences between stitched tiles, and present you with that final "Italian bullseye", which you have to somehow correct. Not sure how many stitching programs have that sort of correction built in.

A less intelligent (more photoshoppish) stitching program that "precorrects" tiles will end up desaturating the whole thing, and leave you with various degrees of uncorrected Italian bullseye that you will never successfully repair.

3) Stitching two row panoramas did result in more distortion in the building elements but it wasn't dramatic or offensive in the images I was taking. But the process of taking the photos and processing them afterwards did take much longer than using the RhinoCam and the results were less predictable in how Photoshop stitched them together.

So my bottom line is that I will will probably return the RhinoCam since I haven't been able to take photos that I would consider aesthetically pleasing despite the higher resolution and easier usage compared to normal stitched panoramas. And since the expense and sheer bulk of the system is significant there isn't a compelling reason for me to keep it.

I would love to hear if anybody else has purchased the RhinoCam and managed to get both high resolution AND pleasing color and exposure since I can't figure out why that isn't working for me.

Ouch, that's a big argument against this thing.

Hello everyone,

i'd like to share some experience about rhinocam

Like some already said, rhinocam is not a tool to make panoamics,

the only goal for me, is to acquire enough sensor size to get the larger the sensor is, te format / large format spirit,
in fact , in addition of the light , and the eye of the photographer, the more you have a bg sensor , the more you picture will look large format.

For the color shifting, i did'nt noticed that effect , it really depends of the lens, and the aperture.
you can take a look a my pictures, you'll see that it's NOT panoramic .

My feeling today , is that panoramics are cool , but in a way , you get so much informations, and a pic with a big fov , will not make the viewer dreaming, beacause he already see all the landscape/cityscape etc.

with rhinocam you can make 10000x10000 px shots, without havig an outrageaous fov....

Finally i can say that the fact that we don't change the axis of the lens, is truly an advantage, the stitch is sooo easy,
and no distortion,

anyway, enjoy, and try !
