How to address over sharpening

I often receive over sharpened images from my clients.

As suggested by: http://www.cambridgeincolour.com/tutorials/image-sharpening.htm

  • Grossly over-sharpened images can sometimes be partially recovered in Photoshop by (i) duplicating the layer, (ii) applying a gaussian blur of 0.2-0.5 pixels to this layer 2-5 times, (iii) setting the blending mode of this top layer to “darken” and (iv) potentially decreasing the layer’s opacity to reduce the effect.

Photoshop Targeting Layers via the Keyboard in Photoshop – Great for Actions

• Option + “[“ or “]” (Mac) | Alt + “[“ or “]” (Win) targets the layer above or below the currently targeted layer.

• Option + Shift + “] “or + “[“ (Mac) | Alt + Shift + “] “or + “[“ (Win) adds the next layer up or down to the targeted layer(s) (note when you get to the top or bottom of the layer stack, Photoshop will “wrap around” to continue adding/subtracting layers).

• Option  + “,“ or “.”  (Mac) | Alt  + “,“ or “.” (Win) targets the bottom/top -most layer.

• Option + Shift + “,“ or “.”  (Mac) | Alt + Shift + “,“ or “.”  (Win) targets all layers that fall between the currently targeted layer to the top or bottom of the layer stack.

Note: these shortcuts are essential when recording actions as they help to select layers, but do not record the specific “name” of the layer in the action.

Lightroom HDR Findings – 5 shot HDR produces better tone in LR

Testing shots in Folder: 2015-11-18 Absolute Avenue Mississauga

Even though J. Kost stated that LR uses on two shots, I ran a 5 shot HDR through (-2,-1,0,+1,+2) using LR and 5 seem to have a smoother tonal result.

1,2,3,4,5 processed by LR HDR and it is the best. 1-5

1,5 processed by LR HDR 1&5 and its tone is not as smooth as using 5 shots

1,2,3 processed by LR HDR 1-3 and its  dark as only the -2 to 0 ev were used.  Still I like that version because I like darkness.

Lightroom forgets Import Screen Settings – Sort order always wrong

For some reason lightroom  keeps forgetting the settings on the import dialog boxes.  I set the options I want, but they are forgotten when I go back and do another Import   (sort order and organize into one folder are always unselected). In order to fix this create a new preset with the sort order and organizing to one folder selected and save the preset.

The next time you use the import dialogue the import settings on the screen will default to none however the sort order and the organize into one folder is retained from one session to the next.

 

Micro Focus Adjustment – How To

As my aging eyes require a bit of help focusing (especially for nature shots) – I have found that the preset auto focus settings are NOT always reliable as released by the manufacturer for each camera body and lens.

To save me time, I put the following information together from several sources,  the first section from: http://www.northlight-images.co.uk/article_pages/cameras/1ds3_af_micoadjustment.html and the second section from Spyder Lenscal.

Both Canon Micro Auto Focus and Nikon AF Fine Tune allow micro focus adjustments to calibrate a camera body to a specific set of lenses.

Here is my technique:

Firstly you can test your lens to see if it is properly calibrated already and does not need any further adjustment.

  1. Download the file www.jeffgardner.ca/ImagesJG/TestPattern/Testpattern.gif  pattern
  2. Using a calibrated monitor, display the above file in Photoshop at 100% (unscaled, exactly 100% on a screen and not on a print).  You should see with your eyes the Moire interference Patterns.
  3. Place the camera and lens on a tripod so that its 100% parallel to the screen (for short lenses, a small mirror lying against the screen will display the front of the lens exactly).  50 times the focal length.  For 50mm lens, 50*500=2.5m (25m for a 500mm lens, perhaps a laptop outside in this case).  The test pattern should be symmetrical
  4. Using Live View – manually focus the lens on the computer monitor test image.  Look for peek pattern visibility, not any particular pattern.
  5. Note the distance indicator on the lens carefully and the state of the image on the LiveView camera screen.
  6. Switch off LiveView and press the shutter button half way down to auto focus the lens.  The lens should not move –  the distance indicator should be identical to step 4.
  7. Reactivate LiveView – the image should be identical to step 4.
