  • 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 :)

Got 6K ? ( link to my LA vista shoot test )

IHey Les,

is that shot from Runyon Canyon? And Red studios is in the shot. Just blocked by other buildings in Hollywood I believe
 
I don't get it.
I'm looking at the 6K still, but nothing in it can be called sharp.

It looks like an up-ressed 4K shot.

Am I missing something here?

Oh, and what is that black line at the top of the image?

I'd venture a guess and say Photoshop Image Size.

If you think image resize in Photoshop would get anywhere, try it and post the result!

Peter: there is detail in that frame that is very close to 1 pixel across. If an Epic can shoot 4K ( using 5K capture ) then take a look at that imagery next to my frame, blown up 800%.
Seems a full resolution still from mono Epic is as rare as a picture of Yeti.

The line is a power line. Yes , Runyon Canyon, and the wind helped blow the haze away.

Eric, take a 4K shot of some detailed stuff and blow it up, and post it here. Compare. Post full res. sample.

Pat: not sure what you mean, you think the image is soft due to the lens ? There are details in that image that are close to pixel on pixel off type of detail. Can't get much sharper. Please post something you think is shot with a lens that does not bother you.

here is a 200% blow up, and I added some sharpening to the previously unsharpened image.

Dude no one thinks you're cool. Just quit being cryptic and share with people what you're doing or don't post. /rant

I wonder what stop is being used? And it is shot through a lot LA air which is going to cause some diffusion as well, LOL!

Les, FWIW, I think what you're working on is very cool. And I don't think you need to share anymore details than you want to. BTW, Sony doesn't use an OLPF on the F65 and instead uses signal processing to remove aliasing, so you're in good company (or bad, LOL!).

But you're going to have to perform more controlled tests (e.g. not shooting through eight miles of atmosphere) w/ more acceptable measures of resolution (resolution charts) to show how much detail you actually have.

Like I've said, I think it's very cool that you're working on this and I wish you all the best ;)!

I don't remember which lens I had on there for that shot, actually. It was either the 50mm 1.4 Zeiss, or the $29 Vivitar 70-210 I had with me ;) Don't laugh, it isn't as bad as I expected !
The sharpening I just added really helps compensate for the haze. I should apply some to the big image as well.

James: I'm not posting to be cool. I'm posting to demonstrate where the images can go if Red puts their mind to it. Maybe their 'rock star' software developers will be encouraged to develop some additional output options for RCX and the SDK. Before Black Magic or GoPro or Sony thinks out of the box first.
The methods I'm using involve custom in-house code and is not available to the public. Work in progress, will improve substantially.

Thanks Peter!
I just want to camera to be as good as it can get.
I can't tell you how happy I am with it now, I feel that as if I have a digital 65mm camera now! And I can carry in in a manageable backpack to boot!
 
There are at least three of us here on RU that have done 8K, 16K, and 24K utilizing multiple R1 and Epics or single camera offset from about 2008 on.

That is a great way to create high res, it's a shame there isn't a display / array of displays to showcase that kind of resolution, but that would be incredible to create a gallery / event that did that. Of course there's always print, but in video that would be incredible... I wonder if the RED team has though of projection stitching for their RED laser projector... 24K projector anyone? (we just need a big wall)...

There are actually, it's just not very common, and it's been done for a long while now. Dome, cylindrical, and now building projections are out there. Using arrays of projectors and sometimes using very special optics. One thing I'm looking forward to about laser projection is how it's going to effect companies doing this type of work. I've worked on some weird installation projections and ride films over the years that require "unorthodox" imaging methods. It's real fun stuff.

Her's a nice example of a fantastic building projection using an array of projectors (one of my favorite at least):

More recently Amon Tobin's last tour involved mapped projection for his live stage show using multiple surfaces facing different directions.

Then you don't know Les. He's very cool.

I recommend that you sit back and learn from the Master, grasshopper...

I use Hoya Pro1 Digital filtes to protect my lenses because they are high quality and have such a good anti-reflective coating that it is sometimes very hard to tell if they are on the lens or not. One feature claimed by Hoya on this particular model of filter is that of anti-alaising for digital cameras. I have seen no image degridation with the filter on and just figured that this "anti-alaising digital filter" feature was nothing more than sales hype targeting an uninformed customer. I confess I am an old film guy, and after reading Mosaic Engineering's web page, it appears I may have been the uninformed one. Les, if you don't have a Hoya Pro 1 Digital filter to add to the equation, I live in L.A. and would be glad to lend you one. Also most of the Nikon primes ever made, both vintage and modern if you would like to include any of these in your tests. You can PM me.
 
I replaced the OLPF with a coated IR cut filter. I plan on shooting again this weekend, taking better notes of my lens choices during the shoot. No lens meta data on old glass made it a guessing game last time, I forgot when I used each lens.
