  • Created discussion thread Sd14 can see through things
    I was playing around with my SD14 after I bought a visible light blocking filter for the lens and took out the hot mirror.  I was taking pictures in the house and I noticed this effect. The cloth ...
  • Try looking at the image I posted with one eye closed.  If your visual processing  work like mine,  you will see an increase of the depth effect.
  • What I have noticed is the SD14 and 15 seem to be very sensitive to the quality of lens mounted. That seems strange because they are not really pushing the limit of most lenses in terms of resolution.
  • Yes, this has a look that would be hard to duplicate.
  • Created discussion thread Does this look like a Merrill image?
    I downloaded a DPq0 raw file from this here I processed it with x3f tools and added detail and detail boost with the Topaz ...
  • I have always thought that the 3d effect was due to low noise,  sharp edges and slightly blurred background. I shot this the other day to see if I could produce the effect.  X3f tools, SD15 and ...
  • I shot this with a Pentax K5 II and processed it with Lightroom and Topaz adjust. Detail and color was added with Topaz and sharpened with Lightroom. The lens was an old Pentax M42 F1.8 shot at F5.6 ...
  • x3f_extract *.x3f converts all the files in a folder with noise reduction on and DNG output.
  • Take a look at how much better x3f tools handles SD15 blown highlights than SPP does. Sigma should fix this problem. This has been my only complaint about the SD15. This might be old news around ...
  • I downloaded some sample raw images from and converted them to DNG with x3f tools.  A little sharpening added with Lightroom. I am ...
  • I gave x3f tools a go on some SD14 files, now I feel the need to process a bunch of old files over again. The green cast that was always hard to remove without turning highlights magenta is gone ...
  • Replied in Lighting
    The lighting was manual strobe bounced off the white wall behind me.
  • Created discussion thread SD15 400 ISO ETTR
    I am still happy using my old SD15 and EX 18-50 F2.8 lens. This was shot at 400 ISO in neutral mode, auto exported from SPP and vibrance added with Lightroom. I see a little grain but nothing to ...
  • I wonder how they are implementing phase detect if they are using the same chip as the current Quattros.
  • Created discussion thread Back of hand light measurement
    I have found that using the back of my hand can be used as a gray level exposure reading much like using a gray card. It's really easy to get fairly accurate light readings. The AEL button on the ...
  • Created discussion thread Batch editing without sharpening.
    Is there a way to batch edit x3f files in SPP in the auto mode without having SPP auto add the default sharpening?
  • I would make a copy of the image in Lightroom. In the copy image reduce the saturation of all colors except blue. Then blur the image. Then you need to download enfuse plugin for lightroom. Enfuse ...
