General / Re: Here I go again..8bit, 16bit, 32..

The only reason for 16 bit is because I need to go that way for pipeline workflow, otherwise I would gladly gone with jpg.

It would have been a easy fix if Agisoft would allowed to replace photos when just generating textures. But using the standard version I dont know of any easy way to batch switch from .tif to .exr without doing it manually photo by photo..

It's only for texture reasons I want the 16/32 bit not for generating mesh.

Hi Breezz! I'm sorry but I'm not the right person to ask about what camera you should go for:(
but I was interested to know if you have used Camerapole as you mention, if so, how do like working with it? which or what kind of camerapole are you using? Home made or bought?

Yes this is the only information I found as well David.

What confuses me a little is, are 16bits input in Agisoft still 16/32bits when saved out as exr, or have the inputs tiff files already been converted to 8bit and then converted back to 32 exr?

On the other hand it might be better as said to save out exr's all the way to be on the safe side. Exr files are usually smaller than tiffs which is good..but it adds one extra step in production for me since Adobe Camera Raw doesnt save out exr, I first have to save out tiffs then batch save them to exr in photoshop..

Thank you Alexey, unfortunatly I have standard version..

I've asked this question before and try and re read some post about Agisoft handles bit depths.

So when using 16bit tiffs and save out texture as tiff they are converted to 8bit, does that mean that my 16bit tiffs are converted to 8bit in Agisoft? or will I keep my range saving out my tiffs to exr? or will it be the same like converting my 8bit to 32bit when saving?

To get the higher bits workflow all the way do I have to use EXR all the way in agisoft?

Will the saving 16bit tiffs be fixed?

Tried your tip David on one of my easier scans. Had no idea about this and it seems to work pretty good!

Usually my scans are only one chunk so getting this to work I need to have at least two chunks to be able to get Agisoft to align chunks to begin with, next step would be to merge chunks, correct?

This is what I did, please let me know if there are easier way to do this David:)

Duplicate chunk so I got two chunks
Aling chunks, didnt bother much of the settings just keep them at low pointbased and 1000
Next delete one of the chunks
Do the selection and make sure it's selected when duplicating your chunk again.
Invert the selection on one of the chunks, now you have a exact split when removing respective part.
On one of the chunks I played with grow selection or shrink selection so I got some overlapping just incase when decimating.
Did my decimating and combine chunks with combine model checked.

I also tried and continue splitting and adding more chunks which also worked fine, so you can have different amount of decimation and detail where needed..

Thanks David!
I had no idea you could split actual mesh into smaller chunks, or do you mean splitting the photos to smaller chunks and re process all steps again?

Didnt look at memory consumption on my first decimate, but second one is hitting the roof. On the other hand I think the first one would have aswell, arent that much of difference between them but maybe this one just hit the limit:)

I have a few more to decimate so I'll see if they are any different in memory and speed.

Thank you Alexey!

What is causing Agisoft to be super slow when decimating some meshes? I have a project with different chunks. One chunk consist of 80 photos that I have generated a mesh from and one chunk with 94 photos. The first one took like 10 minutes to decimate the second one have been chewing for 1.5 hours now and still 6 hours to go.

The meshes are pretty much the same kind of object, sure the second one have more polygons but cant  understand why it will be such big difference in time..

Thanks bigben, when you say recalculated lens calibration are you talking about doing your own calibration with the Agisoft lens calibration tool?

Thank you Marko and Marcel!

The lenses I have is a Canon 27-70mm ultrasonic and a Canon 50mm ultrasonic. The 24-70 I usually set to 35mm.

The tripod is of course best option but many times it is not suitable and takes extra time and limit your freedom of moving around.

So does anyone knows how sensitive Agisoft really is regarding ISO noise? And would it be possible to use Adobe Camera Raw for removing some of the noise you might get?

Guess I just need to play around and try but if any one already have come up with some conclusion it would be nice to hear about it:)

General / ISO settings, f number and so on..

Hi everyone! A question about best settings for getting sharp photos. Im somewhat new to what would be a best general camera setting. I totally understand it will be from case to case, time of day, amount of light and so on. I dont expect a golden setting cause there is none I guess, but more a overall guide what is better and not.

As example, a cloudy day, using a hand held camera, I want as sharp picture as possible with minimal depth of field and motion blur. The only way I see to achive this is going up in iso setting. To keep depth of field away I assume it's getting F-stop to as high as possible (F13-F22). Then to keep the motionblur of shooting handheld is increasing shutter speed. To do this I only got ISO left to get the light in. I use a canon 5d mark III. People say you can go really high on iso on this camera before any noise appears.

So any general thoughts, tips of how you are working with the camera settings would be of great help!

Thinking of maybe buying one for work, but not sure if it's easy to work with, but looks like some of you already have some experince and got some good results:) And together with a Camranger device I think it could be useful.
But it sure looks a little unstable to move around with quickly... but maybe not as heavy as trying to hold a tripod over my head..

Any one have any experience with Camranger device aswell or anything similar?
