Many years ago when I used to photograph what I thought would be my masterpieces, I knew in the back of my head that what would be most meaningful would be the family photos that I made. Now, after more than 50 years of making photographs I am selecting those films that I deem meaningful and I am producing black and white photographs in my darkroom for my children to have.
Just before the pandemic I broke out with a bad case of shingles and I couldn't do anything for months. When I was able to use my arm again, I still could not play guitar but I was able to go into the darkroom to make some photographs. I made a series of silver gelatin prints for a folio that I titled "Homage to Photographers of Old." After that I made a set of 28 photographs titled "Robert Cameron in Black and White." Then I made a folio titled "Portraits of Growing Up Asian." I just finished a fourth folio titled "Three Generations of Photographs." The last two are more in the line of a photo essay as they include many family photos. My grand father and my father were photographers who worked in the darkroom, so I had many films to choose from.
The pandemic, lasting so long, has given me the opportunity to make these folios. I made 4 sets of folios since I have 4 children. They aren't too interested in these folios at this time, but I'm betting that they will appreciate the work after I'm gone. I am leaving these folios in wooden boxes that I made with the names of each person who will get their copy. Actually, I am making, in some cases, more than 4 copies of these series as I want to leave at least one set of 48 images in a folio for each of my grandchildren I have 3 so far.
Our family has a rich history. My great grandfather came to this country in 1852 and worked, presumably, on either the railroad or searching for gold in order pay off the cost of his transport to this country. In 1864 he traveled back to China to purchase supplies and came back to America to start the first herb store in Chinatown. It was closed by the federal government during the end of the McCarthy era because it was illegal to trade with China by 1957. The family business, at the time, had over $750,000 in inventory (almost 100 years worth).
My maternal grand mother was kidnapped from China when she was a little girl and brought to this country to be raised as a prostitute. My grand father saw her in a brothel and purchased her and raised her until she was 15 and made her his wife. She bore him 9 children and my mother was number nine.
These stories and more are written out and left inside these wooden boxes to be discovered after I am gone. The project keeps me going and it makes my effort more meaningful. It also warms my heart to know that silver gelatin prints will last over 1,000 years when made correctly.
I make slide shows of my work in progress in order to view the chosen images and I arrange them again and again before I make the final prints. Here are slide shows of my projects. Currently I am starting a new folio which I am calling "The Spread."

If you're seriously worried about your family finding and using your images, stop worrying about it and start doing something about it.

a) Have you exported all your edited images?

b) Are all your images keyworded with a rich set of search words and names of people in the images?

c) Have you created and shared your edited images on a useful physical media and / or internet-based shareshite to all members of your family?

d) Have you written a 1-page documentation and shared and discussed that written organization of your work on your computer along with sharing the images directly with your family?

e) Have you aggressively culled and curated your portfolio? Or, are you just leaving a digital episode of Hoarding: Buried Alive to your family?

f) Have you considered commercial printing and possibly framing specific images?

g) Have you considered creating photobooks around events, people or themes from your portfolio?

I don't believe anyone will take the time to look through my photos. My first wife, who died about ten years ago, kept a wonderful set of albums of my photos, all her life. Not once has any one of our kids nor grandchildren asked to look at them, though I occasionally remind them that they exist.
I don't bother to save any thing that I didn't think was good enough to hang on the wall; those either hang on the wall, or in a stack that I rotate with those currently hung. All will exist until destroyed after I too am dead.
