Bloombuilder: Using Generative AI in Bloomfilter

Bloombuilder: Using Generative AI in Bloomfilter

In this video, I discuss AI and how Bloomfilter is incorporating it into its product. In future sessions, I will cover how the Bloomfilter team integrates AI into our SDLC and dive deep into how we implement AI in our codebase — including a short coding session to demonstrate how we actually code it. But today, I just want to talk about our product’s relationship with AI.

I started this conversation because of the cringe looks I get from some of my friends when I tell them we are building AI into our platform. There’s been so much hype around AI lately that some people in the industry — especially practitioners and implementers of technology — are becoming exhausted by it. And I understand that. Many products are simply adding AI prompt-to-content generators — often with dubious value — just to claim they have an AI-enabled platform.

A Summer Month with Foma 400, in 35mm

A Summer Month with Foma 400, in 35mm
  • Camera: Minolta X-700
  • Lens: Minolta MC ROKKOR-PF 1:1.4 f=58mm
  • Film: Fomapan 400
  • Development: XTOL 1:1, rotary developed

Historically, I have bounced between a variety of film stocks. In order to get better at photography, I have been trying to reduce variability in my process. So, recently, I have been limiting myself to using a single film stock for a period of time or for a set number of rolls. I want to really embrace each film; learn how to best shoot and develop it, and learn its unique characteristics.

This summer, I had a few backpacking trips planned. I wanted to bring a classic black-and-white film along, and I wanted one that would be extra kind to skin tones. People wear less makeup and tend to get dirtier when backpacking, and I wanted a film that would help tame wrinkles, creases, and dirt. Fomapan 400, with its classic large grain and extra red sensitivity, seemed like it would be an ideal choice. After shooting six rolls of Fomapan 400 in 35mm under varying conditions, I think I’m starting to understand it.

Printing Hasselblad Accessories

Printing Hasselblad Accessories

After using a Hasselblad 203FE and Zeiss Planar 110 f2.0 for about a year, I found myself wanting to improve the shooting experience. Though the 203FE is practically dwarfed by cameras like the Mamiya RZ67, I’ll acknowledge it’s still more of a studio camera than a street shooter. Despite that, I enjoy attaching a hand strap and taking it along for a photo walk. The trouble for me comes when I want to throw a filter on the front.

The Carl Zeiss Planar 110 f2.0 has a bayonet 70 filter mount. Purpose-made filters of this type are expensive, but the real problem is that useful filter variants are almost never available for purchase. Additionally, the aftermarket bay 70 adapters are not very good; they have bent metal springs that never catch properly, they rotate out of position, and they fall off the camera. The Cokin P series adapters work fine when on a tripod, but the corners of the oversized square frame catch on pockets and are generally a nuisance when walking around. If I wanted something to suit my needs, I’d have to make it myself.

Omega D 8x11 Negative Carrier

Omega D 8x11 Negative Carrier

I have one enlarger, an Omega D3. I sought out this model because it can handle negatives as large as 4 by 5 inches. But, when I decided I wanted to print some subminiature 8 by 11 millimeter negatives, I would be pushing its capabilities in the opposite direction.

The manual assured me that the Omega D was capable of printing Minox negatives. I don’t have the recommended 28mm lens, but a 50mm lens should be able to make enlargements up 3.5 x 5 or 4 x 6. What I really needed was a carrier to hold the negatives in place.

After spending some time searching the internet for the official negative mask, I found that I would need to manufacture one myself. My first thought was to 3D print a near copy of my 24 x 35 carrier; just make the opening smaller. I was concerned that the heat put off by my incandescent condenser would warp the carrier. So, instead, I decided to create an insert for the 35mm carrier.

Harman Phoenix: The First Roll

Harman Phoenix: The First Roll
  • Camera: Minolta TC-1
  • Lens: Minolta G-Rokkor 28mm 1:3.5
  • Film: Harman Phoenix 200
  • Development: CineStill Cs41

I finally had a chance to shoot a roll of Harman’s new color film. Phoenix is noticeably different than other films on the market; the film comes out of the can a mustard color and comes out of the developer a deep indigo. At quick glance the developed negatives look to be black and white. It’s only on closer inspection that orange hues are visible. The purplish base color might cause problems for some negative digitization programs, but I was able to get usable images with a small amount of effort.

The final images turned out well, though not without idiosyncrasy. Pictures shot outdoors under average conditions produced contrasty images not unlike other daylight balanced films. It is outside of average conditions where the film began to show its unique character. On mostly blue-sky days, the film seemed to produce pure whites which enhanced the clouds. When shot into the direction of the sun, even under rainy conditions, the lack of an anti-halation layer was obvious and overpowering at times. It seemed that every time I used the spot meter on the TC-1 to preserve details in the shadows, I lost them in the highlights, so perhaps the dynamic range is somewhat limited. Finally, when shot at night Phoenix may have imparted slightly more orange than would be expected from a daylight film.

There is no doubt that this film has quirks, but I enjoy the character of Harman’s Phoenix. I will undoubtedly shoot more of this film, though I will be mindful of the dynamic range and halation.

2023 Year in Review: Camera Usage

2023 Year in Review: Camera Usage

Modern cameras have evolved towards a uniform set of ergonomics. If you are looking for a new, high-end, mass-market camera, there’s a good chance the one you get will be covered in black plastic, have a hand grip on the right side, and place the majority of controls within the reach of your right thumb and forefinger. And there is nothing wrong with this uniformity; these cameras are like this because the layout works. Vintage film cameras, on the other hand, are what evolved into this form, so they come in a larger variety of shapes, sizes, and layouts. The layout of film cameras is also influenced by the type of film and the functionality that was available when the camera was produced. Film cameras simply have more diversity with regards to form and function.

Since I dropped back into the world of film photography, and my eyes were opened to the number of choices available, I have been searching for the kit that works for me. I tried a lot of cameras. After an obligatory TLR phase, I briefly thought that mid-century rangefinders would be the camera for me. I eventually realized that I was looking for two different cameras. When I go out with the intention to take photos, I like a medium format camera with a large aperture manual focus lens. When I just go out, I like a small, capable point-and-shoot; I’m looking for an alternative to the fine-in-their-own-right iPhone cameras.

As time moves forward, preferences change and get refined. This is how my camera choices have evolved over the past year.

a bad photographer: color prints on black and white paper

a bad photographer: color prints on black and white paper

In this video I experimented with creating colorized prints on regular black and white paper using Rockland Polytoner. It started with me mixing up the chemistry, and learning that pouring alcohol into hot water creates a lot of nasty fumes. I then created prints three different ways. First, I developed the print directly in the Polytoner and then fix. Next, I developed in Polytoner and bleach before fixing. Finally, I developed in Ilford Multigrade before toning with the Polytoner and then fixing.

a bad photographer: developing color film

a bad photographer: developing color film

In this video I cover the techniques I use to develop color film. I am not a darkroom expert, I have only been developing color film for a couple years, and I mess the process up 2 or 3 times out of ten. So, if I am being honest, I might not be the best person to learn from. However, stoping to think about and explain the process has helped me, and I hope it can similarly help others. Or, maybe, some nice person will notice a mistake I make and point it out to me. In and case, we will only get better.

For the demonstration I developed a roll of expired Kodacolor VR-G. Though there were no obvious problems with development, the results were not amazing. I expected that. I decided to create the video while developing this particular roll of film because I assumed that I would make a mistake. I frequently make development mistakes, so the added distraction of also shooting a video would only increase the risk of failure. I am happy that the images turned out as well as they did, even if I did have to do a lot of post-processing.
