Inflating JPEGs

Is there any way to make the final JPEG files larger in size? Some are coming out 13 MB and smaller, and I need them all to be at least 17MB. I can understand the file being smaller when considerable cropping has been done to the image, but some of these images' crop is minimal.

The original TIFFs are over 100MB. I'm just baffled.

Any ideas, anyone?

TIA

Why do you need them to be 17mb?

I too am curious why they need to be at least a certain file size. Normally, they have to be under a certain size.

We see these posts occasionally where someone is trying to meet the criteria for a stock submission, its almost always a misinterpretation.

Correct. This is the guideline in terms of file size: 'Uncompressed file sizes of more than 17MB. This means you must use a DSLR camera with at least 6 megapixels.'

Often times the detailed submission guides offer alternatives to simple fioe size requirements.

13mb jpg is compressed, the uncompressed size in photoshop is probably in the 40-80mb range.

OK, let's see if I'm getting it: I've this JPEG file that Windows Explorer reports as 15.5 MB in size. When I open it in PS, the Info Panel reads 'Doc: 48.0M/48.0M'. Is it safe then to assume that the requirements are being met?

This is what the stock agency lists as one of the causes for image rejection: 'The uncompressed file size of the image is under 17MB. The uncompressed file size needs to be 17MB or above. If you have a camera that is capable of producing an uncompressed 8 bit file of over 17MB then leave it that size.'

If you set the jpeg at the highest Quality setting when saving/exporting, you should more than meet the requirement. You'd likely take a different approach if you were saving it for the Web or, say, sharing with people via email.

You might want to contact the agency as to whether they have a "maximum file size" limit..

Tony, I've set PhotoMechanic to export the JPEG @ 100% quality, no scaling, and 300 ppi, in AdobeRGB colour space.

What size (resolution in pixels) are the typical images that fail the 17MB limit?

As an added consideration, the file size can be affected the amount of detail present/lacking in your images. For example, a shot of a clear blue sky will likely produce a smaller file than a shot of busy, leafy leaves and such.

You say that "some" of your image files don't reach 17MB, so the question is "Why not?"...

YES. You don;t need to change a thing. You file is nearly 50MB uncompressed. No problem.

Yup, size will always vary based on image content. Some of the images that 'don't meet the mark' are of a single bird on a featureless background, for example.

Here's one image that based on my previous understanding I wouldn't send in because it's only 11.1 MB:

But now that CyberDyneSystems confuted my initial assumption I can send such images in. Thanks, CyberDyne!

Yep, that image is 48.3Mb 'Uncompressed' so send it in!
