360 panorama + speed of spin
Hi, I am fighting with sharpness of my images. I am using T-rex 700 electro with custom rig for my panoramas.
I shoot on 1/1250 and speed of the rig is 1.8sec for one round. I take 9 pictures but they are not sharp as I want.
What is your time for one loop? The reason of blurred pictures is movement of my camera or vibration of the heli?
What is your experience?

Here is one of my project to look - net finished yet ;-)

Enjoy

It actually looks pretty good. The only thing is while its loading it looks a little funky. After it loads it looks good.

Take Care,
Cheers, Patrick

Hi., thank you.
This sample is not involved.It's sharpness is good enough to present.

But my last pictures are not sharp enough...

There is more to getting a crisp image than shutter speed. Proper ISO, F stop and exposure settings will get you what you want at your target shutter speed.

My best suggestion is go outside, set your camera to X setting, spin the camera by hand (or hold your mount in the air and rotate) and observe what set of settings work best with your camera/lens combo. Do this with a number of different settings. I've found ISO 200-400/F5.6 along with proper shutter speeds get me the best results in nearly every condition with my camera/lens setup. Your results may vary. Hence the suggestion of testing on the ground.

1/1250 is not fast enough with heli moving and the camera spinning. I would go f4 1/4000 on 200 iso on sunny days.

It looks fine
It looks fine, I also made some aerial sphericals and I got some blur on the pictures, finally I find the problem, my lens got a hard landing some time ago and it looks fine, on ground the focus is OK, but flying, the vibration makes some internal parts to move…
Maybe you will have to use photoshop to fix some misalignments

I use to shot at 1/400 with ISO 400, but my mount takes 12 seconds to make a complete turn, I got 17 Pictures with a 11mm lens on a sony alpha 350 DSLR

My website is on the way to be modified, but you will find some examples

Marty,
I don't see anything wrong with the panos - they look great to me! Show me where they're blurred.

1.8 second for one rotation seems pretty darn fast! Do what iflybyu77 said.

Again, looks good IMO.
The only thing is while its loading it looks a little funky. After it loads it looks good.
This is typical of panoramas when they load (at least those made with Pano2VR). You can specify parameters for this.

Yes, I usually shoot on 1/1250 or 1/1600.1/1000 with ISO200 and F5.6 seems to be the "minimum".
Now I changed the rig rotation to 2,3 sec.It should be better than 1,6 sec but I wanted to avoid paralax errors.

Here are my other heli panoramas and especially those above the dams without light are blurred.

Egypt seems to be the best.

What do you mean that I should set something with loading of panoramas?The first loaded is preview image and then the original.

aambrose means you could set it so it loads in fewer blocks than what you have. Pano2VR allows you to set how many - I prefer as few as possible as the typical pano is only 2mb that I create, so I won't have "greyed" out boxes that are intertwined with properly rendered ones. I like either grey (and a "now loading" ) or full rendered.

Marty,
It looks like you reduced the quality of the panorama since the last time I looked at it. Possibly to make it load faster??? I would go back to the quality you had earlier and maybe add a "Loading..." progress bar. Just my 2 cents.
