Ray Stone Posted February 15, 2018 Share Posted February 15, 2018 Can anyone please shed some light on a small problem I have? At the moment I am not able to use Adobe Photoshop and therefore cannot convert my condensed MP's to MB's to make sure the size of 17MB size is in keeping with Alamy requirements. Somewhere, a while ago, someone sent me a simple equation that works this out. Does anyone have that information or any other way? Thank you.

spacecadet Posted February 16, 2018 Share Posted February 16, 2018 If your camera is 6MP or over the images are big enough for Alamy assuming you don't crop. If you do, stay above 6MP, or about 3000x2000. I use 3250 as the minimum. Link to comment Share on other sites More sharing options...
Sally Posted February 16, 2018 Share Posted February 16, 2018 You can always use Alamy Sizechecker to check your photos before uploading to be sure http://www.braeside.plus.com/photography/alamy/alamy.html Link to comment Share on other sites More sharing options...

Unfortunately I am with another outfit who deal only in MP - thier rule being all pics must be at least 4MP. Great advice. Thanks a lot. Link to comment Share on other sites More sharing options...

The simple formula for practical purposes is Size in MB = 3 x Size in MP. So a 6MP file is 18MB (for an 8 bit image). Link to comment Share on other sites More sharing options...

When taking pictures on my Nikon which uses a 4:3 aspect ratio, this is exactly the same minimum value that I use for the long side when cropping/downsizing. But my new Sony RX100 uses an aspect ratio of 3:2 so although i still use 3250 as a guide, I could potentially use a different number. 4 hours ago, Sally said: You can always use Alamy Sizechecker to check your photos before uploading to be sure http://www.braeside.plus.com/photography/alamy/alamy.html Yes.. I use this too... a very handy free little utility to check any images that I've cropped and so am a little unsure about. Link to comment Share on other sites More sharing options...
Ray Stone Posted February 16, 2018 Author Share Posted February 16, 2018 Thanks, Matt. I am well in on most of my pics. I have a Nikon too. Obliged to you and other members for your advice. Now all I have to do is get working. Cheers. Link to comment Share on other sites More sharing options...

That's what I was quoting for. I didn't know Nikon did a 4:3. 3250x2163 is my default 3:2 downsize for high ISO. About 6.7MP. Link to comment Share on other sites More sharing options...

Hmm.. now you've made me google the specs of my camera for a second time today! :-) You know i think you're right.. I think I found bad information the first time I looked today.

spacecadet Posted February 16, 2018 Share Posted February 16, 2018 No problem, of course 3:2 is the standard from 35mm. film. It's second nature to think of it as standard. Even though I had a 4:3 p&s for five years. Link to comment Share on other sites More sharing options...
