What the heck is this? At alamy 48mb is the minimum size? Why in the name of God? And How am I gonna achieve that? My raw file is 10MB, my jpeg 10MP is 4MB?! LOL!

Dino...
Open your 10MP file in Photoshop and go to image - image size you will see your uncompressed file size, that's what alamy mean.

My 8mp (3mb) file around 22.8mb uncompressed.

couldnt they do that fot themself, to spare us uploading such large files! it takes 1 hour to upload 1 file. of.... I will upload entire portfolio in 100 years at that pace.

I quit Alamy....

Alamy is macrostock, not micro: this is another beast and has its own rules.

You cannot expect to be paid 100 times micro commission without a few extra constraints

I'm new to Alamy and never had any sale yet (my portfolio is tiny), but I like this site because I feel it is another approach of stock photography.

I will try to build here a portfolio with photo that do not sell well on micro sites, not because they are not good, but because they are not aimed at microstock business.

It takes about 30% more time to upload to Alamy. The size is the picture size, not the jpg size. A Nikon D200 shot upsized 131% gives 49MB picture size and about 3-8MB (depending on complexity - overwhites are less) in file size. I use Photoshop CS2-3 bicubic smoother for upsize, and make sure your DPI is 300 minimum.

Piece of cake, but only use shots that are perfectly in focus and preferably with prime lenses. The reason Alamy can't do it is that some shots, when upsized, are really substandard, and you as photographer should judge what to upload and what not. You can't expect Alamy to inspect ALL shots at 100%. They just take samples now and then.

Actually the pixel dimensions number tells you exactly if your file is either above 48M or below because THAT is the number that matters to Alamy. Come on people how hard can it be to understand the concept of uncompressed file size. 4100x4100 pixels=48.1M or 5014x3343=48M. And the answer is NO - 48M is not a joke. The next time you want to fill a wall with a picture even 48M might not be large enough.

nope! they would not accept upscaled 4mp files  they require at least 6mp files original size and it is obvious it needs to be DSLR too otherwise an upscaled image  from a P&S camera would fail the quality standards.
it was announced by Alamy they'd enhance their  QC test  and review every single images like in micro agencies  very soon.it is also expected to fasten review process too.in my opinion it would make them more strict too

just take attention to pixel dimensions size, if reach 48M or more you are ready to alamy.

Correct: I was wrong. The pixel dimension is already displayed in Mb and not in Mp 

So you say, this image is (in terms of size) OK for alamy:






?

But those are not MB (140), but MP!

No, 48MB uncompressed.  Save it as a TIFF and you will see it.  PSP shows it at the bottom status bar, also in the image info window - maybe PS has an equivalent?

A 3888x2592pix (10.1Mpix) image is 28.8MB.  A 3072x2304pix (7.1Mpix) image is 20.2MB.

Roughly a 5025x3350pix image will be 48MB.

you can not sent tiff file but JPG only, upsize your image to 3400x5100 (51M uncompressed) save as JPG highest quality, let see how big they are, and send it to alamy.

Yes, this is OK: a 3400x5100 picture = 17M pixels = 52Mb uncompressed. When saved in JPEG which is actually a lossy compressed format you get a smaller file (here 6-7 Mb) and this is just fine

Just to clarify a point: when Alamy says they want a 48Mb picture uncompressed, you have to understand "we want a 48Mb picture when uncompressed but we want you to compress it in JPEG when submitting it".
