thank you alistairsam. Yes, I can dispose the originals. The problem is that each one has 6.23 Mb. They are 27 RAW (CR2) files from Canon. Do you need all them ?
Perhaps only two photos, one with 180 seconds-Iso 200 and other with 120 seconds-Iso 400.
You can download them in

They are IMG_1992.CR2 (120 sec-iso200) and IMG_2022.CR2 (180 sec-iso 400)
