davidd Posted July 4, 2018 Share Posted July 4, 2018 As a newcomer I'm a little confused about the requirements for images size. Everything I read tells me that my images should be at least 17mb for submission and yet QC are passing images at less than this. The exif and IPTC data on many of my images is less than 17mb, does this mean I cannot submit them? Link to comment Share on other sites More sharing options...
Gareth Posted July 4, 2018 Share Posted July 4, 2018 Welcome davidd. Another newcomer here Most of your images are showing an uncompressed size of 17.1MB, which is fine....but only just! Your Victorian Toys/Beehive/Boathouse images are more than good enough at around 35MB If you're cropping/resizing heavily, then I believe the longest side shouldn't be shorter than 3000 pixels. Maybe an expert can chime in here, but I just checked on one of my images, and it shows a resize to 3000X2000 to be 17.2MB uncompressed. The uncompressed size is the left hand number at the bottom left of the opened image in photoshop, this is the number that Alamy is interested in. (Click the arrow down there and select Document Sizes to see this) The EXIF shows the compressed image size I believe, which will be smaller. The JPEG compression size will be much smaller still. By the way, I like your boathouse image - I live quite near to Hickling, it's a lovely area, especially the NWT reserve nearby - a great place to photograph dragonflies in the summer months. Best regards Gareth. Link to comment Share on other sites More sharing options...
davidd Posted July 4, 2018 Author Share Posted July 4, 2018 Thanks Gareth but where did you get the uncompressed size from and, how do you get to see my images? No objection but just wondered. Cheers, davidd Link to comment Share on other sites More sharing options...

davidd Posted July 4, 2018 Author Share Posted July 4, 2018 Thanks spacecadet, didn't know you could do that. You learn something new every minute of every day! I'm still puzzled mind, I've just followed that route and found the boathouse image and it shows a file size of 34.5mb. How is that when the IPTC/EXIF info on Lightroom shows 12.88?

spacecadet Posted July 4, 2018 Share Posted July 4, 2018 Sensor size and image size are not the same thing. Assuming it's 12.88 MP, there are 3 bytes per pixel, so that's just under 39MB uncompressed. It may be cropped down to 34.5. Link to comment Share on other sites More sharing options...
Gareth Posted July 4, 2018 Share Posted July 4, 2018 Not sure if Lightroom shows uncompressed file size....I don't use LR....I probably should though....I have really old stuff though - CS5/Bridge/ACR/DNG converter etc! To see the uncompressed file size, open it up in photoshop. 3 minutes ago, spacecadet said: Assuming it's 12.88 MP, there are 3 bytes per pixel, so that's just under 39MB uncompressed.

davidd Posted July 4, 2018 Author Share Posted July 4, 2018 Thank you everyone, it's still as clear as mud but I'll just double check the image size in P/Shop every time before submitting. Just seems a little longwinded that's all. Link to comment Share on other sites More sharing options...
spacecadet Posted July 4, 2018 Share Posted July 4, 2018 You don't need to. As long as your camera is 6MP or above (it is), then cropping aside, they're big enough. You still seem to be confusing sensor size, image size and the difference between compressed and uncompressed. Link to comment Share on other sites More sharing options...

Just have a bit of a think about it. You know the sensor size of your camera in MP. The jpegs you send to Alamy are compressed, so probably appear as 5-10MB when you look at "properties" on the files. When you open them in PS, the document size in MB will be three times the MP size. BTW you shouldn't be needing to downsize your images to 6MP (3000x2000). In broad daylight at normal ISOs image quality sholdn't be a problem. You also have all your images listed as RF. Without releases and containing property they should be RM. Link to comment Share on other sites More sharing options...
