Of course we all know how to post and share jpeg but, how do you go about sharing or making it possible for someone to view a much larger TIFF file online.

Thanks :wink:


Why would you want to? Image quality viewed in a monitor is not such that you need huge file sizes. You can reduce the pixel density to 72 dpi and use some jpeg compression and the image quality on a monitor will not be noticeably different.

Good point although some monitors are capable of 100 DPI.

The only reason to share a TIFF would be if you want someone else to collaborate on the post processing. That would need to be a 16-bit (48-bit color) TIFF to guard against posterization/banding.

You cant really see the difference in any 8-bit format - JPEG, TIFF, PNG, etc.

And if you are going to share the TIFF for someone else to edit, why not simply share the raw file? It still has all of the data.

As mentioned above, send a flash drive, burn it onto a CD or there are many cloud services that can do the share. Nikon Image Space, WD My Cloud (if you have a My Cloud drive. I have the 4tb and love it for putting stuff on so I can get it with my laptop when traveling), drop box and probably any number of other photo sharing sites.

However, you have an attendant problem which is not resolved by just getting the file to the recipient.

Viewing it.

TIFF is not one of those browser universal file formats like PNG, JPG, BMP, GIF, etc.

NOT ALL editing programs can open TIFF, and surely not basic internet browsers.


The file browser I have came with Windows 7 and it seem to have no problem displaying TIF files. That may be because I long ago installed Microsoft's camera codec package but that is available from the Microsoft website for free download; every photographer who uses a Microsoft OS should install it.

Those viewers who are (fortunate enough to be) using a Mac can easily open a Tiff file using included-software "Preview."

TIFF requires editing or reader software than can view it. Now PS, CC, and the other Adobe products can view it, because they can open TIFF.

There may be a way with the software you are saving to TIFF to embed a viewer along with the file, but by itself the file is worthless to anyone who does not have software that can open TIFF. If you know the recipient can open a TIFF file in the first place, then I suggest you look into Dropbox, or one of the similar large file solutions.

You open a Dropbox account, you upload your big file to Dropbox. Dropbox then allows you to send a Dropbox link (invitation) to the recipient. He/she then goes to Dropbox and downloads the file to their computer.

Dropbox is relatively (????) easy to set up and use. Then, it's just a question of having a viewer or decoder to open TIFF.

I'm going to assume someone is asking you to send a TIFF format, which means they have the capability to open it. If you are the one making the decision, it may be of no value to the recipient if they do not have TIFF capable viewing programs.

Nearly all viewer programs. including Irfanview, can display TIF files. It is a very standard file format. However the best thing to do would be to convert to jpg, unless the recipient wishes to edit the file. Then Dropbox is fine, it is what I use.

Most on line photo / image services will only allow jpeg due to file size issues. This not only affects the host storage space; downloading a large tiff across a slow connection can cause problems as well.
A lot of free email services will have problems downloading large tiffs as well.
To move them about over the internet use a service such as dropbox. To publish via the internet is not really a possibility.

If you only want them to VIEW the file, I think any Windows program can do that. If you want them to OPEN the file in order to do something to it, that's a different story.

Personally, I do this often enough that I need something really simple and uncomplicated. I have a website. I lease space on a server, and can upload files as I need, put them in directories that I name, and they can be made available by a menu just as you'd expect, or they can have no menu access.

This morning I had reason to share half a dozen TIFF files with a customer. I accessed the website with FTP. I used "mkdir" to create a new directory, and then used "cd" to access it. At that point I used "mput" to upload the files to be shared. Then I sent an email to the customer with the URL for the directory and a list of files in the directory. If anyone attempts to access the directory with a browser, access is denied. But if the filename is added to the URL the browser can access the file for viewing or to save to disk.

The cost of space on a server, a domain name, and DNS is pretty reasonable.

Edit: Here's an image made available on my website with no menu or other obvious public access. The directory is at

http://apaflo.com/nalukataq_preview

But a web browser will be denied access to that directory. The file is at this URL, and anyone that has the entire URL can access it. It's a small 8 bit TIFF, 600 pixels wide.

I have not come across an editor that could not open a 16-bit TIFF. I have Windows 7 64-bit so I can't speak for non-Windows platforms.


I have 64-bit versions of Windows 7 and Vista on computers, and have no problems opening 16-bit TIFFs either. In fact Windows alone does fine viewing thumbnails of JGP or TIF files by it self. It is "Photoshop" type files that need a program.

Very few viewers will not display a TIFF, and very few computers do not have some program, if not several, that display TIFF's.


Was that a HotLink? (HTML code)

If I want to post a picture that I've saved it TIFF, I make a copy and save it as JPEG. When finished, I delete the JPEG file.

I suppose I should have included sharing raw files also. Collaborating on PP work is one good reason to have the ability to share.

This does not seem practical.

It looks as though Dropbox would be the way to go. I think I have a Dropbox account going back to long before I was doing photography.

Thank you everyone :-)
