You dont need to do that. They upsize and convert to tiff you file for buyers.

So, why in my portfolio in DS the  pictures with the Maximum size,  for example: 8000x5000px (7279 KB) are not with TIFF license ?

I wrote a letter to DS support  and they answered "The only additional formats are the ones below. Please see the link:
http://www.dreamstime.com/extensionstable.htm" but the big amount of 3D renders in DS have TIFF format for the Maximum size.

Dreamstime create the Tiff file from the file format you uploaded when a buyer requests it, you don't need to upload a Tiff.

In other words they take a Jpeg and then convert it to a Tiff for the buyer who pays extra for that service  Shocked

It may have something to do with the resolutions of the images you are submitting - the TIFFS are generally the result of DT's upsizing and you may be at the upper end already.  I have a vague recollection of a thread on this......

Who know, are TIFFs created by DT from upsized JPEGs the same quality, as created from original RAW files? I think, it is possible create JPEG from TIFF, losing the quality, but impossible reverse this action. http://www.thephotoforum.com/forum/beyond-basics/240202-jpeg-tiff.html i read the next information: Consider the issue that JPEG only allows for a 8-bit tonal depth in each of the 3 color channels: red, green, and blue ( or 24 bits total, 3x8=24), so any JPEG converted to TIFF will also have an 8-bit depth, whereas an image originally made as a Raw or TIFF file can have a 16-bit depth. And upsizing decrease quality, too!

DT only says that they use "special software" to make the conversions. I believe that they are using some type of fractal program (similar to Genuine Fractals) that "transforms the image into "resolution independent-assets" eliminating the relationship between pixels and resolution. The image becomes mathematically encoded as an algorithm and the pixels of the original raster image are replaced with a new file structure that stores the entire image and none of the pixels. When you open the image again, you can re-scale it to the desired size and the algorithm will generate new pixels while maintaining sharpness regardless of image size."

It must work if buyers aren't complaining.

http://en.wikipedia.org/wiki/JPEG write:
The compression method is usually lossy, meaning that some original image information is lost and cannot be restored, possibly affecting image quality.
Simple example - if you convert true color image to 256 color , you never will get back true color from it!
So i think, this DT additional TIFF, made from JPEG, is only for getting more earnings (if the buyers are so naive)!
