Updated - Processing help needed

Hello,
I’ve been shooting smaller subjects and got a basic understanding of shooting & processing workflow using CR. I’m attempting my first bigger subject(image attached - area to be shot highlighted in yellow) -
CastleScreencap1.jpg

I plan to use a drone(dji 4) & dslr(for areas where better detail is reqd) on ground/tripod. Is it possible to mix photos from multiple cameras? If so any additional steps(like color correction?) to be taken before importing the images into CR?
Any other suggestions/best practices before approaching a project like this? Thanks a lot in advance.

Hello,
yes, you can mix pictures from different cameras.

Thanks for the links Lubenko, had gone through them before you shared the same.
WIP - some 2200 images, all shot handheld, around 2050 aligned. Here is the alignment -

Have a few queries -

  1. Is there significant difference between using tiff & jpeg? I processed the raw files into jpeg. Is it worth the extra time & effort to use tiff instead of jpg?
  2. I have limited resources in terms of system configuration(my specs are in signature). Is it advisable to do the recon/texturing as one big model or breakup into smaller regions? Is there a way to estimate the resources reqd(disk space) in advance?
    I will shout out for any further queries as I keep progressing. Thanks in advance.
