@hmngh Are you aware that your filesize is extremely bloated? Your project is over 100 MB larger than the 20 MB raw that you yourself linked to. That's because when I loaded up one of your files in Photoshop, I saw that they're in RGB color instead of greyscale. This six-step guide will show you how to not only convert from RGB color to greyscale, but also how to properly export files, assuming you use Photoshop to edit:
1.) This file's in RGB color by default, circled in green: https://puu.sh/GQDIS/d06e7b5d38.png 2.) Showing you how to change from RGB color to greyscale: https://puu.sh/GQDNH/2f7cec4ad9.png 3.) Discard color data to change: https://puu.sh/GQDOf/353dee9762.png 4.) Now the file's in greyscale, circled in green: https://puu.sh/GQDQw/e918d2f029.png 5.) Using the export to web option: https://puu.sh/GQDSu/8bc322505f.png 6.) Export settings for 32-color B/W PNGs: https://puu.sh/GQDXR/4e507aad3a.png
Granted, PNGs are always going to be larger than jpegs, but unless they're 4000 x 6000 or some absurdly high resolution, 42 pages shouldn't be 120 MB, especially not when the original raw is just over 20 MB.
