Replacing Textures

[Josef]

Hi,

I have a two-part question.

I'm fairly new to Agisoft, and photogrammetry in general.  Having a great time so far and producing some amazing results from around the world for VR.

Ive had to shoot a lot of low light situations so far.  Ive used a A6300 shooting RAW + JPEG mode using a very low iso, tripod with 1+ second shutter and a mid-deep stop.  Had successful results so far.
 
One tip that I read - and feel free to contradict - is that by shooting RAW and then pulling up shadows and pulling down highlights and lowering contrast uniformly across all photos in lightroom (to a 100% jpeg export), will give a better model as there are more details in the photos, especially shadow areas in high contrast environments.  Does this sound like a sensible approach?  The models seem good so far, but I haven't had time to do a proper A/B comparison.

The second part of my question is, when doing the above, I end up with a very flat texture due to the low contrast photos.  Is there a way to use the other set of identical photos (the uncorrected jpegs) as the texture?  If so, how do I do this, and can it be done without having to realign all the photos? 

Thanks for the advice, loving the software so far!

This guys a bit mad, in a good way, but he mentions what I believe you mean at about 1:52

Thanks!

This guy actually does the opposite..  he is using high boosted contrast images for "better" camera alignment.

What are peoples opinions on this? Is high contrast or low contrast better for alignment?

Nobody has any opinions on the above?
