  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

So is it true that the Gemini produces a soft picture? Do you regret not going to 8K?

I shot this on my Red Gemini 5k, with Leica Summicron-C and Fujinon 19-90mm Cabrio.
I like this camera a lot!

Great video, it reminded me again of why I still prefer the looks of the Leica Summicron-C lenses over the Leica Thalia lenses on a S35 sensor.
 
RED Gemini 5K IPP2 ISO TEST BETWEEN STRANDED AND LOWLIGHTMODE

From Youtube...

Rectangle Studios Rentals just received the new Red Gemini which sports dual native ISO at 800 and 1600. We shot this low light test at 800&LL1600 ISO on a ZEISS Compact Prime CP.2 50mm/T1.5 Super Speed.Compression was set to 4:1 and recorded at full 5K, IPP2 and the no contrast,highlight roll of soft was applied. No additional color correction was applied.

 
A Stroll Through The Neighborhood - RONIN-S + RED GEMINI


From Youtube...

Intrigued by the Ronin-S setup for a RED camera, I bit the bullet and got one. Spent an afternoon getting familiar with the setup, I can say that I'm super stoked with the performance! The gimbal seems to handle the camera just fine! The size of the red (not the weight) limits some of the Ronin-S's unique features... but with some creativity there is a lot that can be accomplished. I was able to mount the camera with the 4.7inch touch monitor attached to the camera. For this setup, I utilized the Ronin-S as is, without attaching a dual handle grip. I used the jetpack v-mount battery adapter and wore the battery on my belt. I could have attached the battery mount to the handle, but I actually preferred having the battery detached from the gimbal. The ability to use the gimbal with one hand was awesome. I shot this with a Zeiss 50mm f1.4 planar t lens as well as the Tokina 11-16mm f2.8 for the wide angle shots. Shot on a RED Gemini DSMC2 camera. I did not use any post stabilization in this video. I have always been curious about using a gimbal on a skateboard, and all of the bike footage I shot while riding a skateboard. The footage on the playground I shot on foot. I'm stoked with the investment in the Ronin-S gimbal. I hope you enjoy this first shoot!

Couldn't pass by this thread without at least giving this one a shot.

gorgeous!
 
Gemini is of course not as sharp as Helium because of the lower resolution.
I was deciding between Gemini and Helium but choose Helium. The main reason is we shot wildlife where you always want to zoom in closer so it was clearly the right choice here. Another reason is that Gemini sensor is large so it would crop with our Canon Cn20x50 meaning we would only get 4.5k while on Helium we get 7.5k.

I think Gemini is great for more documentary work and a bit faster work where maximum resolution is not as important.

Yes 8K Helium is sharp, but Gemini's pixels are much larger - and that seems to do something. We've looked at 5K gemini footage on a calibrated monitor, and it looks HELLA sharp. I think people would be hard pressed to tell the difference.

But practically, there's a major difference. Gemini only allows for one practical reframe (from 5K to 3K), but Helium allows for two (8K to 5K, and 5K to 3K).

... the rest of the story

Keep in mind that the RGB image you see is built from a RAW data set by an algorithm. Cameras that use Bayer CFA sensors don't have a "native" image per se, just a set of values that are used to build an RGB image. Judging sharpness, tonality and many other metrics on default reconstruction results is somewhere between problematic and pointless.

From the beginning, Graeme has followed his version of the Hippocratic Oath - first, do no harm - which primarily means no aliasing. The upshot of this philosophy is that the default RGB image displayed is typically softer than the more "sweetened" image from other camera systems. Once you take the footage into a post tool, be it RedCine-X, Resolve, Scratch, Baselight, etc there are many ways to enhance perceived sharpness.

Image treatments specifically designed for sharpening like unsharp mask, can work wonders - but can also create some artifacts if pushed too far. My personal preference is to modulate the contrast curve a bit and then audition different scaling filters. On most images I start with Lanczos, then Mitchell - but there's no standard formula because image content varies and the scaling filter needs to play well with the elements of that particular image that matter. I would also cite the relationship between the scaler and the scale of the image that can help one find the best option without auditioning every type. For example, on a wider shot with lots of discrete elements I'd look at Lanczos3 or CatmulROM first. On a close up where artifacts might be an issue I'd likely start with Mitchell.

Bottom line - if you're judging sharpness on the default RGB rendering out of camera you are NOT getting the whole story. Assuming the capture was in focus, all 3 of the sensors we are comparing can yield tack sharp images with proper treatment in RAW development and a light touch with a sharpening filter.

OAHU, HAWAII - RED Gemini 5k

This is part 2 of a 3 part video series from my trip to Oahu, Hawaii.

Lens: Sigma 18-35mm f/1.8

 
A week ago I watched a 4K projection of a short I shot on Gemini at Disney Animation's theater for a presentation. Sat in the front row and it looked gorgeous! No sharpness or detail issues at all on a 40' screen and we shot 4.5K on Optimos.

Interesting Blair. What tools do you use to use Lanczos and Mitchell sharpening?

IN A DAY,TERADA HONKE—The Natural Organic Japanese Sake Brewery

From Vimeo...


"Terada Honke has brewed sake for more than 330 years in Kozaki; the ‘Town of Brewage’ located in Chiba Prefecture 87.5km to the northeast of Tokyo.We make naturally brewed sake using organic rice, with the help of the yeasts and various microorganisms involved in sake making. In contrast to the modern mechanized sake brewage, all the work is done manually. We make our sake according to the ancient Kimoto method (a way to ferment with wild microorganisms taking plenty of time) which most sake brewers today have stopped practicing. The only ingredients are rice, water and koji malt(steamed rice inoculated with starch-breaking molds). Our sake is made following the law of nature, borrowing the help of the natural microorganisms inhabiting the air within the old walls of the brewery. "
