As I'm sure others are aware, FAA limits the file size for uploads to 25 Mb (actually a little lower; I have to usually get the size down to around 24.1 Mb for the upload to work). That used to be a problem for me only on panoramas. Now with a D800E, virtually every image I prepare is significantly bigger that the maximum allowable size. Panoramas can easily be double the allowable size. Thus far, I've been reducing the image size and having to use compression (very disheartening). Surely others are experiencing this dilemma. Is there any indication the file size limits might be changed? I've started uploading full resolution images elsewhere, but would prefer not to have to go that route.
It's strictly against FAA advice, but I sometimes use JPG compression to allow uploading higher resolution images. Compression artifacts at quality 10 on Adobe's 12 point scale are undetectable on prints, as far as I can see. Even at quality 8 they are slight. I've never sold a print big enough for this to be a concern, yet, either way, though. I have some images that cannot be output as a JPG. They're too big. I even have some that are too big for a TIF. So I shrink these images until they are capable of being converted to a jpg, and then increase compression to get them under the 25mb limit. I wish I could afford a print to test this strategy!
I would be very interested in an option that allowed me to purchase an inexpensive test strip for a large format print. (Not the whole print, just a strip from some select portion that I choose.) I suppose I could upload such a crop and get that printed. But would they be able to print a 120"x1" strip?
I always upload at the HIGHEST QUALITY POSSIBLE, and unless the image is very large, that is 12 on the adobe scale.
@ Greg: I feel your pain. Many of my large panos cannot be uploaded in a quality file due to the small file size required here. With the 800E there is little hope for anything but a some-what degraded image due to having to meet the size requirements. Unfortunately, some of the best and most interesting work I have churned out recently cannot be uploaded here. Those images have to be uploaded to a site which takes 50MG + images. It would be nice if we could have more MG space for the larger files such as vertical and horizontal panos and generally larger images. As cameras continue to gain in the MP department, less and less will be able to be uploaded without degradation. To my knowledge, there is nothing on the horizon as a solution.
Thanks Sandra and Gregory. It would seem to me that if FAA's primary interest is selling art, they will increase the size limits. If their primary interest is increasing membership, they'll keep existing, constricting size limits.
I was already convinced of your hypothesis, John. I mentioned that FAA does not recommend this because some people who do not understand the technical issues would compress files under 25mb unnecessarily. The ifs, ands, buts and wherefores are a little to technical for many as it is.
