Mosaic Construction question

[kirkster501]

Hi all,

When doing a mosaic  do you take the [say] four greyscale Ha tiles then stitch them and repeat with LRGB and then use these completed, constructed mosaic greyscale channels to do post processing?  Or do you do the individual tiles as completed LRGB pictures in their own right and then stitch those together?

Thanks, Steve

I worked it out;complete the grayscale as mosaic masters first before LRGBHa cominations.

Yup, it is possible to build mosaics using fully processed images and sometimes you're inclined to do this because you have a nice finished image which you'd like to extend outwards into new tiles. I've been in this situation plenty of times and have muddled through - but it is the hard way. The easy way is to build the mosaic from the linear tiles.
