What file type/size is actually stored on SmugMug?

Str8aero

I've been using SmugMug for a year or so - have uploaded 1000+ photos. I use the Lightroom 3 Upload Publishing Manager with File Settings Format set to jpeg and 100% quality.
In reviewing my backup strategy for my photos a good friend and long time SmugMug user reminded me that SmugMug serves as a 'backup' for those photos I have stored there. That got me looking at the File Settings in the upload manager. There are options there to store as DNG or 'Original' - as well as a couple others. I store all my Lightroom photos as DNG locally so I figured I should maybe be uploading as DNG so I have a backup that matches what I have store locally. But then I go concerned about file upload time, etc. (also some question about the maximum file size of 24 MB for uploads?).

So, I set up a little test. I created 3 different galleries - one for jpeg, one for original and one for DNG (I realized that if I was uploading DNGs the last two were probably redundant). I then picked 4 DNG photos in LR3, set the upload manager file settings format according to the target gallery and uploaded the files (timed each upload) Here are my results - note I picked one photo of the 4 for specific measuements - DNG file 21.3 MB on local disk:

Setting: jpeg 100% - took 38 seconds; resulting target photo in SmugMug when selected for download:
3744x3744 jpeg 7.38 MB

Setting: Original - took 27 seconds; resulting target photo in SmugMug when selected for download:
3744x3744 jpeg 1.01 MB

Setting: DNG - took 25 seconds; resulting target photo in SmugMug when selected for download:
3744x3744 jpeg 1.01 MB

As expected (mentioned above) the second two were very close, but compared to the first this is not what I expected. The stored image (apparently) on SmugMug is much smaller when I specified DNG or Original than when I specified jpeg - I would have thought it would have been the other way around? Likewise, I would have thought the upload would have been longer when I thought I was uploading the original DNG versus a jpeg. Can someone explain what is really going on here?
Thanks in advance! Rick

What's your site, I want to see the files you uploaded

We now allow 100 megapixels and 50 megabyte files.

My SmugMug site is http://www.str8aerophotos.com/
The galleries are Studio Jpeg, Studio DNG and Studio - original
They are unlisted... let me know if I have to change that.
Thanks

We ONLY accept JPGs, not DNG (unless you are storing them in a SmugVault). Every file you uploaded is a JPG, you can see them here:
http://www.str8aerophotos.com/homepage/uploadlog.mg?type=all&scope=week

If you have the bandwidth, upload JPGs at LR 100, if you have bandwidth issues, LR90 is really indistinguishable from 100. If you want to store your DNGs, consider a SmugVault: http://help.smugmug.com/customer/portal/articles/93324

Thanks for the response. Your reply "We ONLY accept JPGs, not DNG (unless you are storing them in a SmugVault). Every file you uploaded is a JPG..." certainly appears to be the way it is working. In the SmugVault description (at the link you provided), under uploading states "Use SmugMug's default uploaders (we suggest Chrome) or MacDaddy..." - no mention of the Lightroom Publishing Manager. Can you tell me why there are options to specify DNG, TIFF, PSD, etc. in the SmugMug Lightroom Publishing Manager if they have no meaning - in fact you get less than if you specify JPEG?

We'll update our help pages - but in the SM LR Publishing, you can choose DNG or other if you have a SmugVault. Otherwise, choose JPG.

I thought the limit was 24MB? or is the 50 refering to something else?

tnx

See post by Baldy in the thread Max JPG file size too small for today's cameras for updated sizes.

That thread is in the pro forum. I'm assuming that the changed sizes apply to all account types, but someone from Smug will need to confirm that assumption.

thanks Denise,

I can confirm I'm able to upload 35MB files with HTML loader. It is a pro account.
