Entrance Pupil Database. Wouldn't it be great if everyone entered their values for their NPP / Nodal Point / Entrance Pupil for lens and camera combinations.

Manual Exposure Blending With Photoshop. Beginning real estate photographers may wonder what people in the PFRE flickr forum are talking about when the talk about “Exposure Blending”.
Is this the same as “Exposure Fusion”? No, it’s not. Exposure Fusion is where you combine a number of bracketed images with an automatic algorithm built into software such as Photomatix, Lightroom/Enfuse or other similar applications. Exposure blending is where you combine several bracketed images manually with layers in Photoshop. Since the images are on different Photoshop layers you have exacting control of how the layers are blended together.
This YouTube video by Simon Maxwell, an Architectural photographer working in the UK illustrates how to use exposure blending to carefully control the color balance in an interior shot. You can also blend images with different exposures as well as different white balances. Noise Reduction with Smart Object Stack Modes. Last week we took a look at Stack Modes in Photoshop, and found that all we needed was a layered Smart Object, and we could use the Stack Modes to great effect.

For example, here is an image taken at ISO 3200: Not so bad, you think? See the purple and green “spattering” going on? For this example, we’ll start in Adobe Photoshop Lightroom. Image Stacking Noise Reduction Technique. Hello PentaxWorld,The other day I decided to try a trick that I read about in one of my Photoshop manuals (Adobe Photoshop CS3 for Photographers by Martin Evening).
Even though I have moved onto CS5 it is still one of my favourite Photoshop guides, possibly due to the quality of Martin Evenings efforts.In the manual he discussed some of the many benefits of Photostacking. In a previous thread in this board Manesty discussed Photostacking to achieve combined focus properties through a series of individual images to produce a single image that offered a depth of focus greater than possible from a single image.I would like to offer another use for Photostacking. Photostacking can be used to reduce the effects of noise. The technique is based on the fact that noise generated by high ISO is not always created the same for each photo.
The second photo is a stack made up of 5 photos / captures. Bret Edge Photography » Ten Killer Exposure Blending Tutorials.
