Sure George - Here is my un-scientific response: Embedded JPEGs Converted by SPP Only change was from Eval. Mode to Spot Mode. Everything else is the same each side. The tone of your response did ...

(my emphasis) Scott, Scott, Scott -what ARE we going to do with you ... :-D

Yes, I saw that too ... My problem is with the identical settings and the use of manual exposure being somehow affected by the metering. Perhaps the dreaded word "exposure" is the cause of this ...

Thanks Jan, that helped me to find it in Google Maps: I take back my comment that I made first in this thread!!

Did that but there's only less than 0.1EV between two patches of sky, unless my maths is wrong. :-(

Perhaps there is misunderstanding. The shots I am referring to are of a sunset with a pier and fishers on it at left. Each shot is at f/6.3, 1/160 sec, 0 EC, 100 ISO, light value 12.6Ev,  ...

Thanks for the reply, Jan. I was talking about the tall thing (red arrow) but I can see now that it is probably connected the more distant bridge that is close to the water.

Nice and subtle indeed! While you were doing that, I went over the top in RawTherapee's Color Toning function where you play with an odd-looking curve of hue (Y) versus luminosity (X). Exaggerated ...

I sit about 10ft from a 36", 1080p TV. That's 2K, as I'm sure you know. With my deteriorating eyesight, that's not quite enough these days. I don't particularly need more resolution but bigger ...

Based on context, one assumes that 100% was meant in both cases. Not in my book, Arg. For serious work, I 'zoom in' with specific values in Nearest Neighbor, no smoothing. Those values being the ...

Excellent, Jan. The scene itself spoiled to an extent by that stupid-looking construction over to the left. I've despaired of such stuff ever since the glass pyramid appeared in Paris ...

Splendid shot. Not being into B&W, I would be tempted to color-tone (tint based on tone level) just a little. Like a Harvest Moon, e.g.

I posted a thread about super-resolution recently. Not saying you should follow that to the letter but two actions might help: Shoot about 20 continuous mode shots on a wobbly tripod (IS off). This ...

A very good point, surprisingly not mentioned before (unless I missed it). Makes me glad that my Merrill out-resolves my 1920x1200px monitor even in low-res. :-D This thread should remind us of the ...

Well done. I had forgotten about those Merrill top layer "brighter" pixels, - and I see some darker ones too! We don't see them in SPP because there is a "bad pixel" list in the X3F ...

Thanks. I was typing while you were, see my other post please.

Indeed, the proper viewing distance is said to be one diagonal (27"). And if that gives a cpd of over 50 then the "Merrill advantage" can't be seen without a magnifying glass. ;-) So 1/218 divided ...

At what distance do you view the 5K Mac screen and how good is your close vision compared to the average human?
