A couple more 'Deep Stereo' images using Tri-shots.

Dave, you are quite right in that I have no desire to output images suitable for 55" screen scrutiny, nor do I have such equipment for examination. Output is to the standard 7" stereo cards and a 24" (diagonal) PC monitor in Xeye display in which each image side is approximately 10" wide.

I am using one of three techniques to extend the rear depth where most appropriate:

1) Masking some of the Right Hand wide shot with the Right Hand narrow shot where required. Easiest but can lead to more abrupt intersections.

2) Using the depth map from the wide shot (created in StereoPhoto Maker) to displace said areas of the narrow shot. This gives far less disruption at the intersections but depends on the outcome of the SPM depth map quality. The depth map can also be emphasised and/or curve adjusted when using this method too. This method also avoids exposure or colour discrepancies where the two Right Hand images differ slightly and is my preferred method when available. I may pursue detail working with DMAG9b, depthmap creation software incorporated in StereoPhotoMaker for that pupose, to improve the frequency of usable results.

3) Hand painting a small section of depth map to emphasise the distant areas. All 6 images in post 'https://www.dpreview.com/forums/post/65785630' were normal 2D images with crudely hand painted depthmaps and displacement filtered to produce the results. (The effects on some Ansel Adams photos is amazing and lifts them to new heights.)

Naturally, the advice to take stereos with 3D Gunner's "slightly increased inter-axial distance compared to what is calculated to be "normal" was the first line of approach, months ago, with the equally 'slight' effect on the landscape backgrounds while hyperstereo was unable to include foregrounds with any validity and thus leading to 'miniaturising'.

I will humbly have to forego the approval of large screen scrutineers but still hold to the maxim that "Distance lends enchantment" in my own small way. Twenty one years of DPReview Forum contribution leads me to expect a broad spectrum of valuable responses.

Each to their own !
