> Clarity function in Photoshop for landscape
We can check what is like to process day shot with similar to astrophotography techniques. It is cloudy in Bulgaria for the next week or so and I took shots of the nearby mountain trough the fog with 200mm lens. The fog has similar effect to the earth atmosphere by blurring the image. To observe the stars from the earth is similar to look from the bottom of a pool as the atmosphere cause severe image degradation due to the turbulence.
For the day shots we should not worry for the noise so much as we shoot at low ISO. Even, if after processing some comes up this could be more like an effect to the photo. Most of the best photos has even added noise to look more natural.
So here is a single frame as it shot and compared to the processed result. The processing is as follows:
1. Use clarity to increase contrast of the mid tones
2. Touch a bit saturation and especially reduce the blue channel but not the luminense. There is a blue peak that I want to reduce. I do not want to shift it towards light or dark with the luminense setting, as I will change the color balance. I want to show some green from the treas
3. Touch the curves to correct the shadows and highlights and increase the histogram width thus the dynamic range of the photo (This is the common astrophotography technique). This usually increase the noise dramatically.
As a result we got much more clear image with details in exchange of few noise that we will keep :)
For my last trip to the Rodopa mountain I decided to cross the limits and to target an object that is hard to believe that a non-professional equipment could catch.
While cleaning up my PC I found sequences of shots of Virgo galaxy cluster taken during springs of the last 2 years. Those were attempts to shot this object, but I was not satisfied with the result and left them.
I recently bought a pocket spectroscope for laboratory use. You can find it at Ali for 5$. It is with glass prism and well build. So I did some test to use with a telescope but did not

Reading a new product that claims to be 100x time more powerful then conventional telescope, I realise that this is just an astrograph with a digital camera that is doing stacked images and show them trought eyepiece or App.
