Round three!  Impossible improved on its previous version of PX-680 opacification test film and offered another batch to their pioneers to test.   This time around, I picked up as many as I could (4 packs).

Luckily, a couple weeks ago, I had picked up a ND4 filter.  I don’t have a 680 and/or 690 so this filter was going to come in VERY handy.  For any non-photogs reading this, a ND4 filter reduces the amount of light that hits the film by a measurement of “2 stops”.   When using a SX-70, a camera optimized for 100 speed film, a ND4 is necessary in order to get proper exposures with 600 speed film.    You still have to underexpose, BUT it makes using PX-680 in a SX-70 do-able.

After the four packs of test film arrived, I loaded up the SX-70 and waited on an opportune time to head outside to snap some test images.  After dinner, Synthia and I decided to walk around part of White Rock Lake.  Killing two birds with one stone; a little bit of exercise & an opportunity to grab a frame …

I used the ND4 filter and cranked the exposure down 2/3’rds of the way.   Trusting the ‘black paste’, I ejected it without shielding it, and tucked it away in my bag.

NOTE: When using a ND4 filter with PX-680 film in a SX-70, be aware that the camera is metering for 100 speed film.  Exposures might be a little on the long side depending on where and what you are shooting.  You’ll see examples of softer images in this blog post.   DO NOT think for one second, that PX-680 isn’t sharp.  It’s ridiculously crisp.   

The following afternoon, I burned a few images on my buddy Mike Hawkins; a brilliant guy & solid friend.   He’s been living in Alaska for the past year and just recently got accepted into the Peace Corps.   He’s in town for a month before he makes his way out to Vanuatu (between Papa New Guinea & Fiji) to go teach English.   Ya .. he’s one of those people 😉

I figured a triptych would suit him well.  Hawkins-style; headband, RayBans, some old plaid shirt and his Nalgene.  Word.

Later on that evening, Synthia and I went to my grandparents for dinner.  When we arrived, it was nearing sunset, so I grabbed the two of them and snapped a couple of photos before it was too dark.  You should have seen their faces.  They lit up when the image came out of the SX-70.   “A Polaroid!!!”  Yes, Mema & Papa.  That’s how I roll.

That weekend, my wife and I shot a wedding in Carrollton, TX.   For almost all of the Impossible images I shot, I used PX-70 COOL, but for one image, I used this test film.   There was an elderly couple, that had just finished dancing and I grabbed a quick pic of them as they were walking off the dance floor.    I used the MINT flash bar and had it set, as suggested, at 1/2 power.  I showed their son the image later on and he was ecstatic that I was going to give the bride & groom a stack of ‘polaroids’ that included this one …

A few days later, I went out to play some disc golf with Hawkins.    I snapped one image while we were there.   It was nearing twilight, so the light was fading quickly.  The exposure was nearly a 1/3 – 1/2 of a second.

Later on during the week, I stopped by our local neighborhood convenient store to grab a drink.   I’ve been going here for a good 15+ years and the owners are super friendly.  Ryan, the one I seem to talk to the most was working this particular afternoon.  As I was paying for my drink, I asked him if he would mind if I took a photo of him with this new test film I had.   He smiled and said “Of course!”  We stepped outside and I had him sit on the curb in front of the store.   Because were we pretty deep in the shade, the exposure was a little long (maybe 1/10th).

After I snapped his photo, I took a quick snapshot of their sign (ND4 & -2/3rd’s).  I ejected the film, without shielding it, in direct sunlight.  I cruised back up there later on and gave Ryan the images I took.   I figured he & his family would appreciate them.

Overall .. WOW!  A huuuuuuuuge improvement in the color, compared to the PX-680 V4B that I tested out a month ago.   ALL OF THESE images were shot without being shielded, upon ejection.    The anti-opacification molecule is working wonders.   Granted, if you don’t want a vintage look like the image above has, you might want to shield in direct sunlight.  However, having that look as an option just gives you more creative flexibility on the spot.    How cool is that?

The only thing I’m wondering is, upon the release of these new films, how long will it be before Impossible reveals the camera they have been working on?

    Dude I love your blog and I love these pics. I hope I look as good as your Grandma when I am 82! She looks waaaaaay younger than that. Come to think of it so does your Granddad 🙂

    Thank you!! I really appreciate the feedback re: blog & photos 🙂

    And my Mema? Isn’t that wild?? She’s NEVER dyed her hair. She claims her good looks are because she’s never taken a sip of alcohol or cursed … I’m not so sure about that though. 😛

    This film is incredible. Why more people don’t use this as a medium, I just don’t understand. When you can get it right, in-camera and with film, why waste countless hours editing. The simplistic beauty of instant film …

  4. I am in love with this new film!! I have both a SX70 and a 680; the crispness is astounding. I am based in both Denver, CO and Santa Fe, NM where the altitude ranges from 6,800 to 8,500 and notice that it takes between 10-15 minutes for the film to develop. The colors are amazing.

    Your shots are beautiful! Thanks for sharing your experience with this beta film!

    Thank you for the kind remarks! I LOVE Colorado. My wife and I are entertaining the idea of moving to Denver next year. We’ll see ..

    This film IS amazing. I feel blessed to be part of such a creative community of inspiring photographers. It’s a wonderful time to be involved with instant photography 🙂
