This video addresses these common issues:
1. The lens barrel won't extend (the camera does not appear to power on) 2. The film advance is loud, slow, or makes clicking sounds 3. The date LCD cover has detached 4. The top plate buttons are mushy 5. The top LCD is misaligned in the top plate window
CAUTION: Please watch through "IMPORTANT REPAIR SAFETY NOTES" before disassembling. Disassembling a camera with a built-in flash is dangerous, and precautions must be taken.
I hope this video is helpful to anyone who has a GR10 with one of these issues, or would just like to learn more about this wonderful little camera.

There are many great resources for how to load film into Paterson tanks and mix chemicals, so here I'm focusing just on the film development process itself.
I prefer the Bellini C-41 chemicals, but there are some ambiguities in the process document. So I created this video to show every step of my film development process in the most concise way that I could.
0:00 Introduction + important info 0:54 0. Dry Soak/Preheat Time: 3min
I do not do a water pre-rinse before adding the developer.
1:09 1. Developer Time: 3.25min and up, varies based on the age of your chemicals and how many rolls have been through them.
2:44 2. Bleach Time: 1min with constant agitation – a little over, just to be safe
4:11 2.1. Water Rinse Time: 1min, warm running water
4:25 3. Fixer Time: 2min with constant agitation – a little over, just to be safe

Recording by Evan Dorsky and Callie ChappellMamiya 645 Pro Frame Spacing / Film Advance FixEvan Dorsky2022-12-30 | When I got my Mamiya 645 Pro TL kit, both 120/220 film backs would advance the film too far between exposures. As a result, the frames were spaced too far apart on the roll and I was getting 5-6 exposures per roll of 120 film instead of the expected 15.
After many hours of troubleshooting, I figured out a simple fix (loosening the counter return spring) that fixed both of my film backs, which have since functioned perfectly through over 100 rolls of 120/220 film.
I know this fix doesn't address the root cause of the issue. The real problem is not that the counter return spring is too tight, but that resistance has increased somewhere else in the system. But this fix is simple and effective enough that I decided to make a video in case it can help other owners of defective 120/220 film backs for the Mamiya 645 Pro + Pro TL.

The Yashica-Mat EM sports an uncoupled selenium light meter that requires no battery. If you have one of these cameras, your light meter may still work!
Check your Yashica-Mat light meter against a known accurate one before serious use -- there's no guarantee that these meters are accurate almost 60 years after production.Spaceteam Arcade GameplayEvan Dorsky2016-05-08 | Olin Elecanisms 2016
