Hi all,

I would like to try to seeling picture on Robertharding. In the guidelines, they required "jpg format ... be a minimum of 50mb uncompressed".
How can I save "jpg format uncompressed"? On Lightroom, it seems not possibile, on Photoshop I didn't found anything about "jpg uncompressed" in the settings, there is only jpg and other settings, but nothing about "uncompressed".
And anyway, when I export on Lightroom or Photoshop, jpg files are much smaller than 50mb. They can be at most around 20-25. Original raw files are around 24mb (I have a Sony A7 II)?
Someone can help me? :)
Thank you

X uncompressed means the file size when flattened but before it's converted to a jpeg.

You can see the number you're looking for in Photoshop's Image Size dialog (if you've flattened your image and converted it to 8 bit). Up at the top.

Here's a blog post from PhotoShelter that explains

why any site persists in describing their required sizes this way utterly baffles me.

They have a global ranking lower than Mostphotos and picky like Getty. They go to the 'ohwell' category. File size, compressed/uncompressed depends on the number of colours and details in the photo.

No

Uncompressed file size does not vary with image content. Uncompressed size (in bytes) = pixels wide x pixels high x bit depth

Compressed files can be lossless (TIFF) or lossy (JPEG)  and those sizes do vary with image content and compression level (for lossy formats)
