Question 1

Is it really non-toxic?

Accepted Answer

Yes, 100%. Our solutions are based on natural mineral pigments and plant resins. You can work in your kitchen, without gloves or mask. Our products are tested and certified safe for people and the environment.

Question 2

Do I need a darkroom?

Accepted Answer

No! That's one of our main advantages. Our processes use low light-sensitivity solutions. You can prepare your supports under normal ambient light. Only the final exposure requires a UV source (Luminograph or sunlight).

Question 3

How long does it take to make a print?

Accepted Answer

Allow about 1 hour for your first print (including preparation). Once you've mastered the technique, a print takes 15-30 minutes of active work, plus drying time. The Starter Pack allows you to make 3-5 prints.

Question 4

What equipment do I need at home?

Accepted Answer

Very little: a standard inkjet printer, access to running water, and ideally a well-lit space near a window. Everything else is included in our packs.

Question 5

Which pack should I choose to start?

Accepted Answer

The Starter Pack (€599) is ideal for beginners. It contains everything you need for your first successful prints. If you want to explore further or work in larger formats, go for the Workshop Pack (€947).

Question 6

What's the difference between the packs?

Accepted Answer

Starter Pack: introduction with A4 Luminograph and Iconic Blue Kit. Workshop Pack: exploration with 3 chemistry kits of your choice. Pro Pack: both Luminographs (A4 + A3+) and all kits for intensive production.

Question 7

Can I buy just the supplies?

Accepted Answer

Yes, refills (solutions, pigments, papers) are available in our shop. You can order supplies separately at any time.

Question 8

Do you ship internationally?

Accepted Answer

We ship throughout the European Union. Free shipping in mainland France for orders over €79. For other destinations, contact us.

Question 9

What types of images work best?

Accepted Answer

Images with good contrast give the best results: portraits, landscapes, still lifes. Avoid images that are too uniform or too detailed. Our calibration workflow automatically optimizes your file.

Question 10

What surfaces can I print on?

Accepted Answer

Watercolour paper, cotton art paper, linen canvas, cotton fabric, raw wood... Any absorbent surface works. The Workshop Pack includes premium papers, the Pro Pack adds canvas and special surfaces.

Question 11

My print is too light / too dark, what should I do?

Accepted Answer

Exposure time is the key variable. Too light = insufficient exposure time. Too dark = overexposure. Our guide includes a test chart to calibrate your setup. Also check our Troubleshooting page.

Question 12

Are prints permanent?

Accepted Answer

Yes, with proper care. Avoid prolonged direct intense sunlight. Framed under glass with UV protection, your prints will last decades.

Question 13

What is the Luminograph?

Accepted Answer

It's our UV exposure unit designed specifically for alternative prints. It provides a calibrated, uniform UV source for reproducible results, unlike sunlight which varies with weather and time of day.

Question 14

Can I use sunlight instead?

Accepted Answer

Absolutely! All our processes work with sunlight. The Luminograph simply offers more control and reproducibility. Perfect for cloudy days or night work.

Question 15

What's the difference between A4 and A3+?

Accepted Answer

The A4 Luminograph covers formats up to A4. The A3+ allows large formats up to A3+ and offers higher UV power for reduced exposure times. The Pro Pack includes both.
