Perfect Digital Negatives for Beautiful Prints

done in your home or studio


You need to know how to perfectly calibrate your digital negative in order to have the best results if you print in Alternative Photographic processes such as: 

  • Platinotype, 
  • Cyanotype, 
  • Van Dyke Brown, 
  • Kallitype, 
  • Salted paper, 
  • Chrysotype, 
  • Gum bichromate, 
  • Argyrotype, 
  • Carbon print, 
  • etc.


I can decide how I like my photo during photo editing and have the print come out as I have visualized it.

What you can expect

from this course

You will learn how to create a prefect digital negative that you will be able to use for alternative photographic processes (e.g. Platinum/Palladium, Cyanotype, Van Dyke brown, etc).

I will explain in a free video that you can watch before buying why digital negative calibration is desirable, and the important steps for the calibration.

The course is designed in little steps so you are walked through one thing at a time.  To be sure you will do all correctly, follow each pertinent video while you actually do the corresponding step. I recommend not to watch the full course and then try to remember what you have learned. All the videos are dense and packed with information, not bla bla bla long boring videos, you may need to pause them from to time if you are trying to reproduce live what I show you.

If you are curious and interested in details, you can dig into videos that I called Additional knowledge. 

We will use state-of-the-art free software available on the internet such as:

  • Easy Digital Negatives. We'll be using Gradient Maps or LUT files giving higher fidelity than curves. 
  • GIMP is an open source photo editing software that you can download and use for free if you don't have Photoshop. 
  • the Exposure Time Calculator, a very useful free tool contained into a spreadsheet.


There are lessons that talk about the same subject but using the free photo editor GIMP or using Photoshop (fully explained). They are named accordingly so you can watch those of your interest and skip the others.

Inside each lesson you find an area where you can write your questions, and I will answer to every one of them. It is like a personal full support to the course.

You have granted unlimited lifetime access to all the course when you buy it, including future upgrades.

What you should know

before starting the course

You should already know how to print in your Alternative Photographic process of choice. Although darkroom (dim-room) knowledge is not in the purpose of this video course, you will get useful tips and tools and the best practices for printing in Alternative Photography.  

Consider that being able to keep your darkroom variables consistent (coating, etc.) is a key factor in achieving a perfect digital negative.

If you are beginning to print in Alternative Photography, there are also great external resources to dig into, like the Facebook Group Alternative photographic processes and the same online community hosted at AlternativePhotography.com.

It is amazing what it is possible to do nowadays, nothing can stop you from learning and mastering the art of printing alternative photography!

What equipment you need

to calibrate digital negatives

  • UV lamp

    you must have a lamp (the best are UV LEDs or fluorescent UV tubes), unless you have a dosemeter that measures the quantity of UV during the varying exposure under the sun

  • Inkjet printer

    most printers can do the job but the best have pigment inks and allow you to change the ink density level, you can also decide to outsource the printing of your negatives

  • Scanner (or camera)

    a scanner is recommended, a simple one with manual (not automatic) scan, or you can digitize the test prints using a digital camera, or outsource the scanning service

  • Computer and photo editing software

    you need to use a photo editor like Photoshop, or choose the free open source photo editor GIMP, or Affinity photo, or others you like.

  • Gray/color calibration card

    Needed when digitizing your test prints. Buy a card that comes with documentation telling the RGB or Lab values for its gray patches

At the core of this course

Publishing this video course took more than one and a half years for preparing, recording and video editing. 

My previous experience making thousands of prints was indispensable to understand all the details, as well as doing extra testing to dig into every detail of the linearization of a digital negative, so to explain to you exactly how to have beautiful and consistent results. Working and exchanging test results with highly knowledgeable professionals working in negative calibration field was of great help, proofing my work.

I was printing professionally every day in 2016 using a basic way to prepare my digital negatives. I felt the need to upgrade my equipment (camera, UV print unit, etc) in 2017. I studied and used different calibration systems including QuadToneRIP, Precision Digital Negatives by Mark Nelson, Inkjet Negative Companion by Dan Burkholder and Easy Digital Negatives (EDN) by Peter Mrhar to become aware of all the aspects of the process and finally create a clear calibration workflow for you to achieve the best results. 

I have chosen EDN system free tools to calibrate my negatives so that I could focus on the art of my photos without the need to do all the technical measuring, since with EDN you have:

  • free web based software usable with any operating system and computer and with any printer brand and type
  • evolved automated tools to create better correction curves
  • the best colorizing system for digital negatives (more on that inside the course)
  • up to date information and extra tools to become a better printmaker.  


After having studied different calibration systems and tested key aspect of them I have finally created this video course, a system for calibrating digital negatives that is the sum of all that knowledge and includes the correct practices for printing in Alternative Photography. It is not the video reproduction of one existing calibration system that you can find in a complicated book, this video course is a unique guide by itself, straightforward and very effective.

I opened the video course to the members of AlternativePhotography.com before opening it to the public. Many of them helped me with great feedbacks that led to the final tuning of this course. I was honoured to receive 5 stars reviews from those knowledgeable testers too!


Technical aspects solved

and no Spikes issue!

In an average course, in books or workshops about the digital negative calibration process you have to perform a series of boring, technical operations over your test prints, that can easily create errors. Most importantly you will face a non told but very common issue, spikes. Spikes are sudden bumps in values, reading a step tablet test print, they shouldn’t happen and affect the quality of your calibration. In this video course you will be provided a special, proprietary and unique Anti-Spike step tablet (the main tool for a calibration) which will avoid the issue giving you easier calibrations. Also, in this course you will have all the reading/writing/correction curve made for you automatically by a state-of-the-art automation tool.
On the left the graph showing the spikes issue and on the right the issue solved.

One to One workshops?

Check this out first!

There are many ways to learn how to calibrate your digital negatives, and a workshop is certainly one of the best. You have an experienced tutor that can teach you and above all answer your questions. Workshops are expensive, anything between 500 and 1600 US$, or Euros. The cheapest way is to look for information on the internet and/or buying a book. It can be a confusing experience, and the technical book hard to understand at times. What you will experience in this video course is a clear explanation with loads of visual examples step by step, with the chance to ask your questions and receive the answers like in a One to One workshop, being clear that the answer will arrive a little time later. All this at an incredibly affordable price and, as opposed to the workshop, this video course will always be there for you to revise your information, walk again through the steps with your tutor and your videos, and being able to ask any questions any time.

Cyanomicon

a very simple way to make a digital negative

Mike Ware is an outstanding person and artist, Honorary Fellow in Chemistry, Scientific Advisor to the National Gallery of Art - Washinton, DC, expert for photography conservation, he is the creator of two new formulas to print in cyanotype: the New Cyanotype and the Simple Cyanotype formulas. There is no better expert in cyanotype than him and he's very approachable for answering your questions too!

He wrote alternative photography books (real bibles) among which "Cyanomicon" for cyanotype and "Platinomicon" for platinum palladium, downloadable for free from his website www.mikeware.co.uk

Inside "Cyanomicon" you can also find a very simple way to modify your digital negative to obtain a good print. I used that system when I began printing in cyanotype, before I learned about the digital negative calibration, and it was important to me as an artisan photographer. So, either you print in cyanotype or in platinum palladium you may want to download your book and start reading!

Superb course

Big up to Paolo for the EDN course. Whilst I was already using EDN in a limited capacity, I have improved my workflow and found the course to be methodical and easy to follow, it certainly took a lot of the strain outta my brain. The operative word here is 'control' and thanks to this course that's what I now have with my own creative practice.

Completing Paolo's Digital Negative for Alternative Photography Course has been a complete game changer for me. While I don't consider that I've really completed it as I will be coming back to it over and over again to remember what he said, I have finally gotten over the last hurdle of being able to create cyanotypes that I am proud to display. I have been a commercial photographer for over 10 years and dabbling in cyanotype work for over 15 years. Being a commercial photographer, 99,9% of my work gets delivered as a digital file for someone else to print or put on a website. I decided last summer that I would hunker down and start printing some of the 100,000 photos I've taken over the last 20 years. Besides learning color management and printing in color on my new Epson P900, at long last I have a printer that can properly print digital negatives. Christina Z. Anderson's book got me back into the process, but I got stumped at the point of creating a digital negative that would look the way I wanted it to. Through more stumbling around in the dark, I came across Peter Mrhar's Easy Digital Negatives book and incredibly helpful and generous online resources. I knew that was the way I had to go, but the title is the greatest oxymoron of the century. Learning how to make digital negatives for alternative photography is HARD and not for the faint of heart. Because there were too many concepts that were new to me and because I had no local help or friends to guide me, I had to give up on Peter's method and decided to look into other resources. Then, BEHOLD! I don't remember how I found him, but I was SO THRILLED when I came across Paolo's course!! Someone who is showing me, step-by-step in a practical way, how to use Peter Mrhar's tools?!! OMG!! The timing couldn't have been more perfect. Again, let me restate: creating digital negatives is not for the faint of heart! But Paolo stays with you at every step, giving very clear instructions OVER AND OVER again. That last part is really what's the most helpful. The steps are so many, and you have to be so diligent to do everything the same way every every time, but Paolo reviews them over and over again helping you remember them. Not only that, he shows you what it looks like when something is not right, and my work kept looking like those examples. Lol! The explanation about why it's not really the best practice to try and combine curves and how to work with the curve you've got was very helpful! He is a gifted teacher. Thank you, Paolo, for creating this course at a fraction of the cost of what it is worth! I hope I get to meet you someday and show you some of the work I am doing now.

I am already an alt-process photographer, but wanted to expand my knowledge and understanding of negatives, and what better way than listening to an established artist whose own work is superb. I found the course to be detailed and thorough, and broken down into many easy steps. Having the text displayed also helped. I found that it was best to go through the overview a couple of times to get my head round what was being described before diving deeper into the process a section at a time. Play it over a couple of times first, and use the pause button, it helps! If you dive in straight away you may find some of the terminology and understanding quite overwhelming, but when you break it down and review it, it really is quite straightforward. Being able to use the free GIMP software helped me too, as my version of Photoshop would not accept the process when it came to resizing and aligning the scanned test prints. All in all, it is a very affordable course and detailed process, and helped me sort a few things out in my head. It also led to my negatives being much better calibrated, and this process works for pretty much any alt-process negative creation.

I have been printing digital negatives for a long time and print them as callitypes and cyanotypes. Calibrating by trial and error costs time, nerves and a lot of money for materials. I don't know anyone who has spent so much time and effort perfecting digital negatives. Paolo is a perfectionist and you can learn a lot from him. My recommendation for making digital negatives!

Simple technique that leads to Beauty


In the image above you can see the results of the digital negative calibration I did for Arches Platine paper and Classic Cyanotype formula. A perfect linearization right out of the first test prints, that I used for printing a new photo of my Macro collection and that I will be able to use for all my future prints in that process. 

Although any calibration system is capable to bring you to a calibrated negative I believe that EDN is one of the best calibration systems around. 

This video course will not only explain to you the steps to achieve a calibrated negative but, beside that and more importantly, it will teach you what is essential for you to take care of when printing in your alternative photographic process. This is the real key to success.

It is true that technique can be boring or complex sometimes, especially if reading it from a book. But it doesn't have to be so. In this video course everything is explained with plenty of examples to follow step by step, and you can always ask your questions directly if in doubt in the specific area. The reward is learning how to obtain a perfect digital negative with a simple technique, without measuring densitometry or tweaking correction curves manually! This is not explained well in the books. 


Pricing

My policy is to offer the complete video course at a price that allows the widest public possible to enrol. You have granted unlimited lifetime access to the course when you buy. I will answer all the questions you may ask inside the lessons.

Instructor

Paolo Saccheri

Santa Margherita Ligure, Italy. I began at the age of 12 to freely investigate the world around me with the camera of my father. At the age of 26 I went to the Istituto Europeo di Design in Milan and attended a course for photo-reportage and naturalistic photography. In the following years I worked for different photo agencies while beginning to know and use alternative photographic processes. My life in Lanzarote, where I live as an artisan photographer and professional print maker, brings with it a transcendent impact that fully takes me to the blue of Cyanotype. Technical knowledge and passion lead me to an intense study of darkroom and dim room variables to define the best practices to print in Classic Cyanotype and make perfect digital negatives.
