Large Format Landscapes

I don't see anything obviously unsharp top-left in that photo...

Another re-worked older photo using my improved digitisation workflow, this time showing the entire 4x5 frame.

Linhof Technikardan S45, Schneider-Kreuznach Apo-Symmar L 5.6/150, Kodak Ektachrome E100.

No not the vignetting. Probably it’s the haze then and the fact that at the top right only sees sharp by color contrasts there. The heath at the foreground is definitely sharper to my eyes

I didn't find it being unsharp. I do see vignetting in the sky in the upper left and right corners. But that's probably because no center filter was used, an aesthetic effect some people like. It looks like he used a GND filter.

It's a nice shot. You got the colors very natural looking. What was your scanning and editing routine? I have trouble with negative color film and have stuck with chromes. They're just easier to scan and set the colors accurately.

Thanks Martin. E100 is a great film, and the updated workflow makes the repro so accurate and easy it almost feels wrong. I need to do virtually nothing to the files now except crop out the border and apply some RAW sharpening. I'm like a cat in cream here ;)

Alan,

I scan all of my C-41 as a positive file, and do the inversion in photoshop. I apply my scanner color correction profile to the initial positive image, and then invert it. A good place to start is to use either the levels adjustment in Photoshop. If you hold the ALT key while clicking the auto button, it will bring up a submenu where you can choose the algorithm. "Enhance Per Channel Contrast" is the same is if you were to set the levels for each RGB channel. You can set the amount of clipping for highlights and shadows respectively. "Snap Neutral Midtones" helps remove color casts in the mids. From there I set the gamma with the mids slider in the same levels adjustment layer. This gets you to the first image below. I then use the Color Balance adjustment layer to further dial it in. Finish with a curves adjustment gets you to the second image below. The rest is done with more selective curves layers and a plugin called "Lumenzia". This plugin allows you to dodge/burn specific tonal ranges.

Seems complicated which is why I stick with chromes. But you did a nice job.

Lovely, that reminds me of the Grimston quarries in Derbyshire UK

It's really not once you get used to it. Luminosity masking in particular (the process Lumenzia uses) is very powerful; I use it a lot for editing all types of files, not just colour neg.
