Photos app overly compresses exported files

[TonyC28]

I recently starting taking pictures with a DSLR camera and have been shooting in RAW format. I have been importing my photos into Photos for organization and light editing. For any pics that I want to email I export them as JPGs. Usually it would compress them down to around 5 MBs or so. Since upgrading to High Sierra if I export an edited picture (usually just cropped) it compresses it way down to KBs. For example, I exported a photo that was 21 MB in Photos and the JPG file was 78 KB. Obviously there is a huge loss of quality. I'm not sure if this is by design but hopefully there is a way to correct it. I am selecting full file size and best quality for export, just like I was before High Sierra.

Just tried one export, a RAW, 20mb or so original, no editing just a straight export with maximum settings on the panel and it came out the wash at 12mb.
