Firefox claims: The owner of this site is unknown

Firefox, differently from Chrome, Internet Explore, Safari and other browsers claim our https secure but give an alert because the “owner of this site is unknown”. We are trying to fix this issue without success. We console ourselfves. We are not alone, the bigger networks have the same problem. So we assume that this is a Firefox issue.


Here below the comparison between Firefox and Chrome (Same is for Internet Explorer, Safari and others ) and the scan of our certificate by Quality SSL Labs that rated our certificate with a Green A



What's about the previous site: bigano.com?

We split the previous site.
bigano.com has been totally re-designed an now is only the portfolio site of Roberto Bigano.
All the instructional contents, tutorials and apps for Photoshop are now gathered in this site, included the rbg.bigano.com blog  posts.
Visiting the old urls you will be re.directed to the new pages


Did you share my personal information?

Absolutely not! Bigano Srl is the company owner of bigano.com and knowhowtransfer.com

Consequently the ownership of the site did not change and your contact information was not shared with any third-party.
For any question, please contact us here >

The publisher of the extension cannot be verified.


 Starting on october 2, 2013, due to the new Photoshop’s security policy some applications installed in the last 365 days might no longer work and even disappear from the Photoshop menu. 

This happens because the yearly developer certificate expires.

This has caused great inconvenience to many of our customers and for us it was not easy to support them.

So we preferred to not certificate our installer, but trust in us please!

General Photoshop Error



General Photoshop Error

It seems that this file has an embedded profile that *is not* installed in your system. Part of the Vitamin routine needs the file to be switched to Lab and then converted back to the RGB profile embedded within the file.In order to do it this profile must be installed in your system.

Tip: Convert you file to an RGB profile installed in your system or assign a profile. If you need to keep the original file make a copy.

Double USM

I cannot navigate within the preview window.


Sorry! After you launched Double USM this is not possible. However there is a simple trick. Go to 100% or 50% pan in the area you want to preview, then launch Double USM.

At which dimension should I set the preview?


It depends. If you want to print the file we suggest you to preview it at zoom of 33%. This will simulate properly what you will see on the print,
For web the best is at 100% (considering the published size)
