File:Chrkei_turm.jpg|{{/Nomination|Hamburg, Eidelstedt-North, Christchurch, Tower and parts of main buildung --[[User:Dirtsc|Dirtsc]] 21:56, 19 March 2013 (UTC)|{{info}} Needs a bit of Perspective correction to make the building look straight. A brightening the shadows a bit would also do it.--[[User:Earth100|Earth100]] 04:48, 20 March 2013 (UTC)
'''Comment''' I think the distortion of perspective is so low that it needs not to be corrected. I fear an unnatural look of the tower. The shadows have already been slighty brightened but it was in fact a summers day with harsh contrasts. --[[User:Dirtsc|Dirtsc]] 07:38, 20 March 2013 (UTC)}}

File:Cupressus_arizonica_-_Glauca_-_blaue_Zypresse_-_02.jpg|{{/Nomination|Cupressus arizonica "Glauca", Mörfelden-Walldorf, Hesse, Germany. Focus stack of 8 images, produced with Helicon Focus. --[[User:NorbertNagel|NorbertNagel]] 20:07, 19 March 2013 (UTC)|Some irregularities, 2 examples in notes. --[[User:Myrabella|Myrabella]] 07:37, 20 March 2013 (UTC)
Thank you for your review. The irregularities you marked are however i.m.o. not an effect of inproper stacking but caused by the physical/optical limitations of the stacking method itself: If the object contains '''distant''' and overlapping parts (which is not always the case, but here), small unsharp regions at the boundary inevitably occur, since when the focus is on the distant part, the overlapping unsharp part in the front is enlarged. If this is not understood, please let me know. I'm willing to explain this in more detail. --[[User:NorbertNagel|NorbertNagel]] 17:42, 20 March 2013 (UTC)
Norbert is right, this is a difficult point for metode. But there is as many, stacking methods to overcome this difficulty. I abandoned Helicon focus because it is not very rich in alternative methods. But this software it is possible to force the passage by increasing the number of photos. in this case 20 or 30. --[[User:Archaeodontosaurus|Archaeodontosaurus]] 06:32, 21 March 2013 (UTC) }}
