  1. Here's a very insightful article that every photographer should read the debunks the myth about Diffraction Limited Apertures (DLA): https://jonrista.com/2013/03/24/the-diffraction-myth/. As the author (Joh Rista) writes and proves with images, "IQ from a photo taken at f/22 can frequently be restored to such a degree that it rivals the IQ of a photo taken at f/4." My work is real-world proof that DLA does not tell the full story, given that I've been shooting between f/22 and f/32 for over two decades, and I produce prints that go as large (or larger) than 40x60". One client produced a 6x9-fo
  2. No you don't need to work an image. But photographers aren't supposed to sharpen an image until after it has been resized. Alamy confirms this standard practice in their instructions for image preparation. If you're publishing pictures in print form, sharpening is one task. Another important task is the conversion from RGB to CMYK which can often change/flatten the rich RGB colors that you see on your monitor. Good luck with your book! Mike
  3. Hi, Alan! Thanks for the analysis. Yeah, this new image is world away, for sure. That's the kind of stuff I shoot. And it was captured digitally. I started asking about the skunk cabbage image because it was rejected and I was submitting closeups. Take care! Mike
  4. Hi, Brian! Yes, it's about re-calibrating for stock. And I think I'm going to make my life easier, as you suggest, by providing smaller files. What is the smallest and largest pixel dimensions that you'recommend? Thanks! Mike
  5. Hi, James! Yes, it's all about calibrating. I wonder if you could take a peek at the new landscape image of Virginia bluebells that I posted a few minutes ago, and let me know your thoughts on QC? That'll help me calibrate. Thanks! Mike
  6. Hi, Alan! It wasn't that one batch was rejected. Several batches were rejected and only one image from one of the batches was referenced in the email. Question: Is the QC process done manually or is Alamy using software? This entire thread is about me trying to understanding what the QC standard is. Do you think the attached image would pass QC? Thanks for the advice! Mike
  7. Hi, Brian! That's the original file size after scanning the 35mm slide. There's a little bit of grain, but minimal. I don't understand the standard, given that I'm used to really big files. I never sharpen images until it's ready for output, and that's what Alamy says, too. But I wondering if Alamy really does want some pre-sharpening. These rejected images may be a little soft at 100%, but they're just really, really big files. After sharpening for final output on the customer's end, the picture's great. There's a 6x9-foot mural of a highly detailed prairie hanging in a visitor
  8. How does the submission system work? Yesterday, every single submission failed due to "One or more images have failed QC...." I made about 10 submissions, many with only one or two images that I thought were safe from QC issues. From all of the rejected submissions, I only received one email that stated that one image from just one of the submissions was "Soft due to size." Shouldn't I be receiving an email for each failed submission telling me why an image in that submission failed? Does one failed image in one submission affect other submissions? Below, I've inserted the one imag
  9. Hi! I'm having big problems with the Alamy QC system. I'm an internationally published photographer with 26 years of experience. When I submit my perfectly detailed, sharp, and high-res images, some get rejected, as well as the entire batch! In fact, these are the same image files that I use to make huge prints in sizes up to 40x60. So you can understand my frustration. Thus far, I've found that the Alamy QC system has problems with highly detailed shots of prairies (which is my specialty) and images of flowing water with wonderful motion blur. I can only imagin
  10. Hi, I'm can't find images that I sent to Alamy back in 2006. How do I find those images and update keywords, etc.? Thanks! Mike
