Just kidding, but after I made the video you can check here, where I talk about the new trend of AI creating photography, this idea came to my mind… what if? lol

Let me know what you think about the use of AI in the creation of art!

.

.

I made a test with two different negatives: a very soft flower subject lighted with painted light and a very sharp subject lighted with a very contrasted light. I wanted to see how this printing process deals with different subjects.

I proceeded with some step test to find the corrected exposure for my negatives. I did 2 seconds steps and as you can see in the video I was a little optimist with my first strip of 2,4,6,8 seconds exposure. At the end the correct exposure resulted of 11 minutes.

.

You can see the tests I made in the video below.

I was expecting shorter exposure times ’cause I seen some other boxes made with the same LED giving short exposure times with other alternative processes.

Still I like the slow times when I work with film and so I kinda like to have time to think while I wait for the paper to be exposed.

The Arduino timer is working greatly and it’s a pleasure to use this box!

.

.

I have to learn to pose the emulsion better on the paper. The thickness came out not uniform and there are spots where the emulsion did not spread at all on the paper. Still I have a lot to learn but as a fist try I’m quite satisfied of the results.

The LabOldTech2000 kit is very easy to use and complete.

See you next time with new projects!

At the origin of photography many technologies of printing required the exposure in UV light. At those time sun was the perfect source and the exposure was usually made outdoor. The quantity of UV light from the sun can vary a lot in different seasons or with different weather, plus, baby it’s cold outside now in winter! For this reason I decided to build a UV Box.

I was inspired by some similar projects videos on YouTube but I added a personal touch.

First of all I used an old wood box for wine bottles instead of a modern plastic box. The wood box was in my cellar, free, and wood looks better and more coherent than plastic with old techniques.

Second I decided to add a timer for a precise exposure instead of counting the seconds with an external timer and manually switch the lights on and off.

.

.

Check out the video to know more about the UV Box and see how it works.

I used very common components easy to buy online:

LED stripes: BTF-LIGHTING UV Black Light 5m 300 LED Strips, 5050SMD Ultraviolet 395nm-405nm

Arduino Nano

Arduino Display 1602A

Buttons: GUUZI 12mm

Switches: GUUZI 12mm, 16mm

LED: GUUZI 12V-24V 12mm LED

Power: MeanWell LRS-150-12 150W DC 12V IP20

5V Power: Greluma DC 12v 24v to 5v Step Down Converter 5A 25W

The 5V are derived from the 12V Power Supply with the Stepdown Converter.
The relays are on the 12V power supply going to the LED stripes and have the green LED in parallel.

.

Here is the scheme of the circuit:

As you see it is easy to build, it just requires some electronic/programming skills and a lot of patience. Buying a full 6 bottles box and drink them during the building can help the morale, I’m not sure about the results!

I wish you a great Christmas, filled with joy and the right personal choices!

This is a strange Christmas with too many people trying to cancel it, some for cultural reasons as the European Commission, others finding excuses in a virus that seem to spread only in specific situations.

It is always difficult to find a proper reaction to evil when it’s in charge of our lives, so I was wondering what to do and the question came natural: “What would John Galt do?”. The answer was very easy and so here’s my traditional Christmas image for the year 2021!

This year, more than ever, we are in a war, it’s not a traditional war at the moment but a cultural war. One side is the side expressing all the values that permit to appreciate and enjoy Christmas, the other side is the side that is not able to joy and wants to cancel it.

The premise of Christmas is the freedom to chose between good and evil, Santa made a list and only the nice ones receive his gifts. Christmas is the season when joy must be deserved, it is the season that celebrates the birth of Jesus, a man who taught us that we are all equal and free to chose, a man who at the end gave his life to eliminate the evil represented by the pretense of an original sin defined by evil people to impose their power on others using guilt as their main weapon.

No matter if you look at the Christian faith as believer or simply as an observer of human and political changes, in both ways the meaning of Christmas is clear. The reason why a lot of powerful people is trying to cancel Christmas is exactly to eliminate that meaning.

To be good must be a choice and as a choice we are good toward people deserving it. It’s a season to donate to other deserving people, the nice on Santa’s list. It’s the season to celebrate the fact that we as human are equal and none of us must be considered inferior or guilty for something other people did.

We are in an era when some people in powerful positions want us to believe the opposite of Christmas. They want us to believe we are guilty because we were born with a specific color of our skin, they want us to believe we are guilty if we do not chose to follow their stupidity of the moment also if we see it clearly and think it’s evil, they want us to believe is their right to rule us also when the rules are wrong, they want us to forget reason and substitute our believes in freedom with their believes in controlling us. They want to cancel the basis of freedom and cancel a popular tradition easy to understand by everybody as Christmas, it’s an easy way, much easier than debating the centuries of philosophy that created the western culture of freedom. They want us to forget our power to give to whom deserve, they want us to give them the power to steal all our money so they can decide who is worth of receiving.

In Christmas we can find all the words to express the best of the human kind: freedom, generosity, joy, equality, love, responsibility, choice, etc. etc. They want to substitute all with the new language they use to rule us: a limited freedom, fair share, guilty joy, equity, duty, settled science and so on.

It’s a war, and it’s a war we can win and are winning. To win it we have just to keep to ourselves our values and love for life and give nothing to them. They cannot enjoy Christmas, we can and we must not make the mistake to share it with undeserving people. To win we must not just chant “Let’s go Brandon”, we must deeply feel it and act accordingly.

On the technical side I had some fun using an 8×10″ view camera, a Black and White film, printing in the darkroom and hand painting the image. A video of that will come soon on YouTube… if my GoPro worked properly!

.

This image is inspired by a Buzzati’s novel. Not the right book to read right now, being a little bit too much kafkian, but a book that came to my mind this week and inspired this picture years ago.

See you next week… and we will see if the tide brought something useful…

.

.

See you next week… hoping there will be no more “glitches”!!!

The most important is the vote for the presidential elections in USA.
Dear Americans, vote wisely so I can continue to work on my plans and keep my dreams. If not, I will have to switch to survival mode, exactly as my parents and grandparents did in the 1940s.

.

.

See you next week, I hope with my plans still intact.

In this environment I was thinking at the good old days when the news came from newspapers, just once a day.

See you next time! Still 8 weeks to go…

The fact is that I really like film photography for many reasons and not just for the better aesthetic for some situations.

Here my main ten reasons, you can read just the titles or you can open the video below and hear the complete explanation I give:

• It’s simple
• Better learning curve
• More control
• Film means reality
• Visible without tools
• Variety of formats and cameras
• Aesthetic
• Value
• It’s a slow process
• It’s analogue!

If you want to see a comparison between film and digital, you can read a couple of articles I wrote some time ago:

Digital Fuji Acros vs Ilford FP4 Film

Fuji Acros Digital vs Fuji Acros Film

Until the next time!

See you soon with the Pentax LX!
