About me:

I am a hiker/traveler first, photographer second. I diligently strive to maintain this order of priority. The whole idea behind my photography is to record images of the places to which I travel and hike for future enjoyment. I use the best camera equipment I can afford in order to record those places with as much clarity as possible. I compose images in a way that captures the scene as I am viewing it but I am free to compose in ways that I feel are interesting too. I am not confined to composing for what may be commercially sellable to clueless consumers. I am continuously trying to sharpen and broaden my skills so that my actions do not counteract the clarity and resolution this fine equipment provides. Turning professional isn’t an option. I am seeking to retire, not begin another career.

Great Bustard: And yet not one on "Photographic Equivalence". What has become of MIT? : )

W5JCK, grow a sense of humor.

Some of these courses are so old that they include topics such as how to load a roll of film, High Resolution: Is 2 MPs the outer bounds?, and my favorite, How to pick the right lab.

On Adobe CC Announcements: What you need to know article (181 comments in total)
In reply to:

Rick Knepper: Like many, I dutifully paid $199 every two years to upgrade thusly: CS2-CS3-CS4-well you get the idea. Since last September, I began paying $10 per month for PS CC & LR plus I have a license to use it on two computers plus I get 20 GB of cloud storage. This costs $240 every two years. That price is good for as long as I am subscribed or until Adobe raises the price of the plan in general. The $199 every two years was never a guaranteed price. You get a lot more with CC.

My price will not increase (nor was it ever supposed to increase) to $20/month after the first year as so many were misinformed. Yes, I checked with Adobe before posting this.

Now there are those folks who only upgraded every other time or only when a must-have feature was released, then I can see the frustration but OTOH, these folks can also be seen as dead weight in terms of the future of PS.

Part 2

I guess that leaves the objection of "renting". You were already renting PS and didn't know it. If you intend to be a long time customer of Adobe which I will be, I don't see the problem of this pricing model. If I quit being a customer of Adobe's, then I'll probably be laying down my cameras too. I can't tell you how much software I have laying around that has been obsoleted by the OS, the gear, the lack of support.

On Adobe teases new 'Focus masks' feature article (58 comments in total)

CSx used to cost me $199 every 2 years for upgrades and the CC version costs me $240 over the same time period and it has produced several features and enhancements not available in CS6 that I can't work without.

On Panasonic Lumix DMC-FZ1000 First Impressions Review preview (1282 comments in total)

Using the Studio comparison tool, I see no reason to own this or any camera with a one inch sensor especially if one's primary format is FF. I was drawn here yesterday because of the hubbub over the RX100 III. Same reaction today. IQ is too compromised especially when fine detail is necessary.

Of course, the RAW isn't available yet but I downloaded the jpegs of this and the 5D3 (as I did with the RX100 III) and even on this modest laptop, viewing at "Fill the Screen" size in PS (making it a relatively small image), The differences are quite plain to see.

The FZ1000 and the RX 100 III images look nearly indistinguishable significant in the sense that the lenses are this super zoom versus a relatively moderate 24-70.

On Sony Cyber-shot DSC-RX100 III First Impressions Review preview (2970 comments in total)
In reply to:

Rick Knepper: So, I believe f5 = f10 approximately (2.7x mag. factor). There are some landscape shots at f5 in the Samples which have very poor edge/corner sharpness for f10, though consistent with Zeiss' 24-70 lenses in other formats. If f5 were actually f5 in terms of DoF, then the images aren't bad. :)

Thanks EcoPix for reading and understanding what I wrote. I have little interest in any system with a sensor smaller than FF so I may not speak with the same command of the jargon others might. I am only here to check this camera out because Luminous Landscape gushed so hard in their review. Their stock fell a few hundred points in my eyes by suggesting that this camera is "pro level". uh uh Not with a Zeiss 24-70.

Am I reading this correctly? The 5D3 beats the D800 in the dark end.

In reply to:

RRJackson: Here's something I don't understand at all. Metering on modern cameras can break the frame down into thousands of segments for complex metering calculations...but nobody can seem to make a metering system that prevents highlight clipping. No way at all to reduce the exposure if the highlights are clipping? Really? In 2014 we can't make that happen? The system can analyze 91,000 segments of the frame, but can't tell if one of them is clipping?

if one studies shadows carefully, most cameras render them too dark. Nikon cameras render shadows less dark than Canon cameras i.e. more realistically. I compared the two systems in controlled conditions with settings designed to produce optimum exposures (I don't like the under-expose by 3 stops on purpose testing) and the results validated what I had been seeing during normal shooting. I agree that the key is to render the shadows realistically, not remove them altogether via HDR or high ISO abuse.

Wondering why Sony won't release a FF version of the a77 while releasing a 36 MP A7r with much poorer AF performance?

This is heavier than the Canon version and just as white.

B-rad: 50mm at $999.00 to do macro? I can see many insects leaving town with how close you will need to get to get a good close up of something small. What a joke.

How do you explain the Canon 50mm macro, Sigma 50mm macro, Sony A mount 50mm Macro & Zeiss 50mm Makro?

On Using third-party lenses on Sony Cyber-shot a7 / a7R article (490 comments in total)

I am visiting here only because I saw the article at Sony Rumors criticizing DPR's conclusions. Without reading SR or DPR's article, I already have a strong opinion about adapted lenses based on my experience over the years adapting many other brands' lenses to my Canon cameras. The OEM alignments for camera/lens combos have to be precise and it's a miracle that copy variation isn't a bigger problem than it is but introducing an adapter (3rd party or OEM) has to increase the incidence of copy variation even more.

I long ago divested most of my alternative lenses to be done with adapters.

I will not be interested in the A7r until a full range of native lenses become available and field results made known.

OT: I will probably wait until Sony produces a longer lasting battery.
