And Blue. Gate to the backyard. Pentax 645z with 90mm f2.8.

 

This might sound like a commercial for a product but I assure you it is unpaid testimony from my own experience. I use two cameras for most of my work, a Pentax 645z and a 67ii, both medium format. I have RRS Arca Swiss style QR plates on both of these and I never had a negative issue with either. The vast majority of my shots are done using a tripod, on which I have the RRS lever release clamp. I found this to be very secure and quick to use, far faster than turning a knob. Perhaps because of the size of these cameras my workflow works well with the qr plates, clamps, and tripod. Regards.

Hi Doug, the update photo function actually does work but it takes over a week for the servers to "digest" the update. I have been using the update photo function for the last couple of months and that is what I have seen. Regards.

I currently have the NEC PA242W (which is now replaced by the similar PA243W) and I love it. Not only does this support a wide color gamut but it has inputs that can handle multiple cable types. I have three computers connected to my monitor using display port, dvi, and hdmi and everything works beautifully. And it is less expensive than EIZO.

I lost track of the days and used up my "one photo per 24 hours" W/NW limit so if someone wants to start Fixed Focal Length Friday, be my guest. Otherwise it has to wait until tomorrow.

 

Thank you for adhering to the No Words Forum posting rules! Regards.

Thanks for the reply. I have a pretty good idea of how the ionizers work but my main question is will the alpha particle emanations harm the CMOS sensor of my camera? The alpha particles are quite massive and energetic; the Nuclespot contains a 5mCi source, which is very strong for a device available to the general public. Is there any evidence that these could harm the sensor? My camera is the Pentax 645Z. I would remove the lens, open the lens (sensor cleaning mode) and let the Nuclespot do its work.

Thanks for the replies. Just a heads-up, the Nuclespot polonium ionizer is available under limited NRC license. One does not really purchase the Nuclespot but leases it under license. Regards.

When I switched from film to digital format I was hoping to finally be free from problems of dust contamination but, alas, that did not happen. Now, instead of dust on my film I have dust on my sensor. Usually this is not too bad but in some cases it really is troublesome. I have used various methods to remove the sensor dust, such an air bulb blower and wet cleaning, but some always remains, possibly because of static charges between the dust particles and the sensor.

 

Question: Would it be possible to use something to dissipate the static, such as the Nuclespot polonium ionizer or similar, without hurting the sensor (my camera uses a CMOS sensor). I propose that one could remove the lens with the camera facing down and place it over the alpha generator for a time. My hopes being that the ionizer would knock the dust off the sensor. Any thoughts?

Here we go again!

Somewhere I saw that PhotoNet earns in the neighborhood of $500 a month. I guess that would be enough to pay the bills but I don't think it would be much of an incentive for a business of any size to continue the effort. I could be wrong. Regards.

I've got a bad feeling about this.

The crepuscular rays are a nice touch and I like putting the horizon low to give that big sky feel. I agree with the previous comment about increasing the tones of the foreground. I realize this is a strongly backlit scene but having the values of the foreground so low makes it, to me, recede a little too much.

In keeping with the original concept of POW, I am moving this thread to a forum that permits discussion of the images. As we all know, the NWF does not permit this.

I moved the thread mentioned from the NWF to Casual Photo Conversations. Discussions about the image are not permitted in NWF, so in keeping with the original concept of Photo of the Week I moved it to where they are.

We're finally getting the band back together. It's an HTTP 410. Checking now

Thank you! I'll buy you guys a beer. Regards.

Technicalsupport gets my thanks! Once they were contacted the fixes came pronto. Regards.

I could be wrong but I don't believe that Namemedia is the owner any longer. I think it was picked-up by Creative Live. Here is an excerpt from Greenspun's blog:

Scroll down to the bottom Fall 2016.

Well, it looks as though Doc Greenspun's noble experiment is finally coming to an end.

Interestingly, at least to me, I have always been able to google search my last name and the first hit returned was my account here at PhotoNet. Not any more. In fact, this site does not even show in that search. I think this is called "death by a thousand cuts". Regards.

Yes, always the optimist. I would hate to lose control over everything that I have uploaded on this site.

I, also, am getting the 404 error. Perhaps this is just the servers doing their weekly auto maintenance? In any event I think the time has arrived to start whittling down my posted portfolio, if possible. Regards.

I was afraid of that. Thanks Andrew.

Thank you to all responders to my questions! Ed, I took a look at the Parallels pgm website, perhaps that is the solution. Andrew, that is unfortunate about the LR6 installer and Big Sur, I had high hopes in that direction. I do not want to go the subscription route since photography is basically still a hobby for me. My ignorance of the MacBooks is a real hindrance. Could I get a new Macbook Pro that has BigSur and downgrade it to an earlier OS easily? All of my experience is with Windows systems (and some Linux).

I should mention that the new laptop would be for travel and that it would be used primarily to download files from my 645z for a quality check of the images but any serious editing would still be done on the WIndows workstation at home. Also, I do have a tether pgm that I would occasionally use with the laptop. Any additional thoughts would be appreciated.
