Errr.... how do I make a 24mb jpg?
Discussion
This makes no sense to me, I've heard of it before. How can the quality of a file be judged on file size alone. If you had a shot of the moon for example and there was a lot of black sky it would greatly reduce the file size.
Do they offer any other measurements or just file size alone?

Check the terms. A lot of places won't accept upscaled images as they arent actually better quality.
A 12mp image upscaled to 24mp resolution isn't a 24mp image. It's just a 12mp image where youve got photoshop to guess the missing pixels to make it the same resolution as a 24mp image. The exact same image taken on a true 24mp camera will be infinitly sharper and more detailed than the upscaled image.
Only way to make a true 24mp photo Is to buy a pro camera that takes them.
Seems a littles excessive though. Last time I dabbled with stock images, they wanted no smaller that 10mp.

I looked at that Munter and yes it works, but what a faff. I'm not going to save each of the images I wanted to upload as a tiff and then reszie them and booger around with all that tat.
What a waste of time.
Errr.... anyone know of anywhere else that I can (try and) flog piccies (Ha!) that doesn't require a 73gigbyte jpg?!!!!!!!!!!!!!!!

Obviously depending on your camera, you should with most modern cameras be there already.
Take a photo using your camera on the highest quality setting. Open it in PS and at the bottom left you'll see two figures - the higher of the two is the one that you want to hit your threshold for Alamy. The actual] filesize you see on your hard drive won't be 24MP, but the uncompressed size is, and will therefore pass (assuming the camera offers sufficient quality settings) for Alamy. If you don't quite hit the right size, you may need to resize slightly - but don't overdo it, as you will run the risk of it failing their quality standards.
I can't explain what it all means, but I managed to sort someone else's Alamy entry on this basis, for information the use a lower-end Nikon DSLR (don't know which model as I use Canon).

I see my files are all 34.5mb or so in size uncompressed.
So it looks like I don't have top fart about with them!
Whew!
And thanks!

It's possible to upscale in 10% steps without reducing IQ but you've got to have a high quality source image in the first place
lol good job I'm not an Alamy contributor ehIf necessary, interpolate (upsize) the file to 24MB using a specialist, professional software package. If you have a camera that is capable of producing an uncompressed 8 bit file size of over 24MB then leave it that size. We recommend Abobe Photoshop although other software is acceptable. If using Photoshop version 7 or higher select the bicubic option. We advise that you do not use “step” or incremental interpolation. Check your software’s default settings to ensure that all sharpening is turned off.

I actually work for Alamy so this interested me. It looks like you've answered your own question already, but I thought I'd post a useful link to a thread on the Alamy forum.I see my files are all 34.5mb or so in size uncompressed.

Getty talk about file size as uncompressed file in memory, which is down to pixel dimensions and depth (jpg=8bit)
A 4-5meg job will expand to a very large size in memory and its this 'file size' they base their processing and pricing on.
Edit see this for example:
http://www.gettyimages.co.nz/detail/photo/christch...
51.3 MB
5184 x 3456 px (17.28 x 11.52 in.) - 300 dpi - RGB
File size on download 6.97 MB
