Eclipse photo RAW file exporting to less that 1 MB jpeg

[Sfbotkin]

Eclipse pictures 16.6 MB file size is exporting to less than 856 KB jpeg!!!!

I can export another photo and it exports correctly.  Smaller file size of course due to becoming a jpeg, but not such a small file size.

I have quality at 100%.  I have not checked limit file size and I have not resized it.  I do not understand why the exported file is  so small.    I don't think I will be able to print a file this small!!

I tried the online chat with adobe.  The person was of no help.Does anyone have an explaination or a fix for this??

I don't think this is a problem at all. Does the JPG look like the way you want, with the visual quality you want? If so, then not a problem.

JPG is a compression technology, it is supposed to reduce the size of the file without much loss of quality. Photos such as an eclipse photo, which have almost no fine detail, are highly compressible without much loss of quality. Seems like LrC is doing the right thing to me; nothing needs to be fixed.

The size of the file does not determine if a file is printable. The size of the image determines how printable the file is, and for JPGs, there is no relationship between size of file (bytes, kilobytes or megabytes) and size of image (number of pixels, width and height). Plus, as stated above, if it looks fine in terms of quality on your screen, and it has sufficient number of pixels, then your prints will be fine.

Your file has relatively little detail - mostly black pixels. This type of file compresses very well - as opposed to say a green jungle. I see nothing amiss here. 

@dj_paige 's comments here are correct.

Thank you for replying.  That makes sense.
