Sigma DP0 Quattro shots

Blustons, Kentish Town, England was until it closed last year (2015) was a rare example of an arcade shop and as such was afforded a Grade II listing. Unfortunately, it sat empty for a while but it has recently opened again and appears to be continuing in the 'smattah' (Yiddish for clothing) business - just like it had been since 1932. It is great to see this iconic shop in use again.

A Sigma dp0 Quattro photo of some swans for your inspection, shot at 1/320 sec, f13, AE = 0, ISO 200. The camera has the latest firmware. SPP = Ver 6.3.2 All SPP setting are centred and both noise are far left buttons. This photo is not for artistic merit (pretty much goes for all my pics ;))

Exported from SPP to jpeg and sized for uploading here in Lightroom with no adjustments. Below are some Lightroom 100% screen grabs.

Here is the original Sigma raw file to download if you wish: https://dl.dropboxusercontent.com/u/13067037/SDIM1020.X3F



and the 100% screen grabs are below:







Hi,

I had another go at these same crops, using SPP6.4 and Daylight WB. Thanks for the opportunity to contribute.

Thank you TN Args. A while back, I too did have another crack at that file and got a small improvement, as you have. But that shot was taken at a f/13 and I think this is the problem as it looks like diffraction is ruining the image. I now never use a smaller aperture than f/6.3 on the dp0Q. Plenty of DoF even at f/4.5. If I need something at the front of the image to be in focus with a good DoF , I'll step back and crop later. Looking back, I ruined a lot of photo opportunities in places I'll probably not re-visit.

Also, I've screwed up a lot of images using SPP with the wrong settings for the Quattro. I now start with Chroma and Luminance at second from right and sharpness at -2.0. Crispy, I normally leave in the middle. The rest I do in Lightroom.

One final shot from Flamstead last week. These must have been the best looking, insect free roses I have seen in a long time.
