Sigma DP2 w/ Yellow #8

It was incredibly overcast today so it was somewhat of a pointless exercise.

Julian- I was able to convert them to B/W in SPP. However when I transferred them out as TIFF's they were not B/W. Do you know what I did wrong? I had to convert them to B/W in Silver EFX. They looked better on SPP. Is there something on the save function when putting them on the desktop that I missed?

The first three are DP3, the fourth one is DP1, and the last one is DP2.

Steve I quite like the rendering here. All I know if I process in SPP using the Monochrome tab it always exports as Monochrome. I export Tiff's always. Not sure what is happening there. i tend to use the latest version of SSP which now converts all the old Sigma camera's as well. I do know it has glitches but never heard of this particular one. I think also if using the SPP monochrome raw converter I cannot see how using a coloured filter would affect it either as essentially each layer of the sensor measures luminance and not colour, it is apparently the thickness of each layer which can determine the colour spectrum assigning those values to each pixel a sit were, rather than inventing them as a brayer sensor does.
I'd try this. Process the Raw file taken using the filter, in SPP monochrome mode. Then select 100% of the blue layer. You will then be excluding the other two layers the red and the green. Which will then only give enough information for a monochrome or blue image anyway. If it turns out a full coloured Tiff as you are at the moment I'd say that is very odd. Also I wonder if you select the Green layer If you will have an image at all, or at least broken up.
It may also be worth trying it in SPP 6.1 and also SPP 5.5.3 to see if they behave differently.

Is there a manual for SPP? I think I have the newest version.
 
Steve on the top bar of SPP click help and then ''SPP help'', it brings up the manual. The same bar click help and then 'About SPP' will tell you the version you have . The latest being version 6.1


THANK YOU!!! I am about to take the dogs out for a few hours but when I get back, I'm going to retry those photos. The SPP version of B/W looked better.
 
I like the portraits, Steve. I have a real hard time getting either my girls (wife and daughter) to pose.

Rob,

Here is a photo take at the same time with the X100 to give you some idea on of the Yellow filter on the skin tones. With the caveat that yesterday was completely overcast. This is just OOC converted to JPEG to so I could attach it. F2.8 with a +.07 on the exposure compensation.
