Good to know. Thanks.

Alright, thanks for the advice.

As it is now, yeah I can live with it. I just want to know if it will get worse over time.

Hey all, just a quick question. I have a Nikon F with a shutter that exposes the right side of the negative (left side of the image) more than the left side by about 1/3 of a stop. I took some pictures without a lens, and concluded that the effect was not really noticeable right now. My question...

If you use a motor with a higher rpm and a cardboard disk instead of the record player you can capture higher speeds as noted above. Photoshop is a good idea too. I'm not familiar with the shutter of the Retina I, is it focal plane? I like the "mechanical" nature of this method, it's something...

That's a good point. I suppose I could record a couple videos of it spinning for, say, 15 seconds and then play each video back at 0.25x speed (so its slow enough to count) and count the number of revolutions. I would then figure out how many revolutions per minute each video was and average the...

There is no reason why you need to use a turntable specifically. You could buy a small motor and attach a cardboard disk to it and achieve the same result. Of course the faster the motor the more accurate the measurements will be. Doing the calculations, a speed of 200 rpm seems like a good...

Hello everyone. I've been meaning to test my Nikon F's shutter speeds, but I've found that the shutter speed testers currently on the market are either too expensive or not accurate enough. So, I looked towards some more DIY solutions. An interesting way I've found involves photographing a...

Alright, thanks for the response.

Hello everyone. I was trying to remove the damaged gears on my 60s era Beseler 23CII so I can replace them, but I ran into a problem. Here's what I was able to do so far: To take out the old gears, I first unhooked the spring wire and turned the counterbalance cylinder one revolution clockwise...

Thank you for the detailed explanation. Yes, that makes a lot more sense now. A final question: These tests will create a "personalised" development time and EI for the film/developer/enlarger combination you tested with. But does the brand of VC paper you choose have a significant effect on...

I just want to make sure I'm understanding you correctly: First I should shoot a few frames of a normal contrast scene (placing the values in their correct zones) at various EIs and look for the lowest exposure that gives me slight detail in zone 2 after developing the frames. I would determine...

But doesn't each zone equal a stop difference on the negative? Surely the number of zones do matter in this case, since a negative can only hold so many stops before clipping/crushing occurs.

Hello everyone. I've been learning about the zone system by myself for a little while now, both online and through books. I just want to make sure that I am understanding it properly, so if someone who is more experienced than me could help out by addressing any misconceptions I have and...

Here are some photos of my negatives on my brightly lit monitor. Hopefully this helps with diagnosing the problem.
