Try one Pre-Screen
Try is the guest door to 101 Pre-Screen. You can run one photo without an account. The result is a set of observations about what the image shows: stroke, clarity, and limits of the photo. It is not a certificate, not a grade, and not a price.
A guest photo is private unless you later choose to publish a research note. Selecting a photo does not grant that permission. Replacing or removing the photo does not either. Read the disclosure on the page before you submit.
After the guest try, a free account includes one Pre-Screen a month. Paid memberships and credit packs add more. The current allowance is on the membership page. Opening Try does not spend a credit by itself.
If you want the longer explanation of what the model looks at and what it ignores, read How Pre-Screen works. If you want a third-party certificate, that is a separate decision with PSA, JSA or Beckett. Their sites list their own fees.
