Steve66 Posted September 21, 2010 Share #1 Posted September 21, 2010 Advertisement (gone after registration) I was talking to a stock photographer who told me that buyers of stock photos will not consider a image who's resolution is below 12mb. This would then preclude the M8 , is the 12mb statement correct? Link to post Share on other sites More sharing options...

Frase Posted September 21, 2010 Share #2 Posted September 21, 2010 Alamy file size is minimum 45meg ish, all you do is up-res the pic to any size they want. Link to post Share on other sites More sharing options...
Paul Glendell Posted September 21, 2010 Share #3 Posted September 21, 2010 Hello folk Alamy minimum res size is 24mb - it changed a few months ago because everyone was up sizeing and it was deemed silly to do this when the client could do it. I don't know about everyone else but my M8 files open at 29 MB so no need to upsize for Alamy. I have photos in other libraries and the requirement for 50 mb files has been reduced in both cases. I shoot editorial images. If a library specialises in commercial clients then maybe they need bigger originals. It depends on which library your photos are going to.

Wolfgang Esslinger Posted September 22, 2010 Share #4 Posted September 22, 2010 my M8 files open at 29 MB Paul Glendell Photography ??? That is strange - mine does 10 MB only. Link to post Share on other sites More sharing options...
SJP Posted September 22, 2010 Share #5 Posted September 22, 2010 It is not clear to me whether we are talking about megapixels or megabytes. a M8 file gives 8 bit tiff file of about 34MB and 16 bit tiff file of about 68MB, this is the uncompressed format that I image stock agencies want to have.

Paul Glendell Posted September 22, 2010 Share #6 Posted September 22, 2010 Okay folks a bit of confusion. M8 has 10 megapixel sensor. I open the RAW(DNG ) files and adjust them in Capture One 5 software, then save them as Tiff Files. The automatic file size that is saved is 29.5 megabites at 8 bit. This is the size that the file is without any up or down sizing. When I save a DNG File to Tiff at 16 bit it comes in at 59.1mb I, certainly would be interested to know if the files opened as DNG and then Saved as Tiff files are bigger on any other software? I always shoot DNG and Jpeg fine the jpegs come in at the same size when opened in Photoshop. If you are shooting for photo libraries it goes without saying that you should be shooting DNG and saving to Tiff. Don't use the jpegs at all. Does that help?

wattsy Posted November 10, 2010 Share #8 Posted November 10, 2010 TIFFs should be about the same file size regardless of how they're created (eg whether from DNG or via an in-camera JPG). They'll differ a bit because the images will be similar, not identical. All standard 8-bit TIFFs of a given pixel size will have exactly the same file size regardless of the image content.
