  • Yes, that the one! It is a very useful way to subtly increase contrast and "pop" in specific areas. I used to use it a lot, but I gradually move to using curves adjustment layers as I like the ...
  • Turns out I still have the action in my Photoshop. There were two - the orignal created color burn and dodge layers, and the PwL II action simply created a Soft Light layer with a neutral fill. ...
  • In addition to being the name of a capture technique, "Paint with Light" was the name of an Photoshop Action written by Chip Springer. This was popular in the post processing forum 10 or 15 years ...
  • Looks nice; glad you got it worked out! Dave
  • First, shooting only the night sky, with no other reference points such as ground objects, trees etc., is challenging for any panorama software. It is more difficult for it to detect overlapping ...
  • is your question about how to take the shots for best results, or how to process shot you have already taken? If you have already taken the shots (and don't have the opportunity to reshoot) then ...
  • Replied in Fallacy
    Yes, another way to think of it is that the size of the blur (and thus its visibility) is the same on the sensor, and on any given size print, regardless of the number of pixels on the sensor. But ...
  • Replied in Pay...
    No, he mentioned two cameras that have different sensor sizes, but then proceeded to ask question related solely to the resolution. The difference in sensor size was irrelevant to his question and ...
  • Replied in Pay...
    He didn't ask about anything related to sensor size. Done. As Gerry has already pointed out, the OP didn't ask about different formats nor about depth of field, nor did the person you responded to ...
  • Replied in Pay...
    It seems more than a little presumptuous of you to be questioning why he wants a new camera. He merely asked about a couple specific things that he perceived to be ramifications of that. He ...
  • Replied in Panic...
    But if he want the equivalent depth of field he merely needs to stop down about one stop, and adjust the shutter speed (if movement is not an issue) or ISO to compensate. He has the the freedom to ...
  • But in the meantime, the OP and anyone else reading this thread should understand that the instructions given in the video (at least as described above) are wrong, and won't solve the problem. As ...
  • Well, but wait! Depth of field is critically a function of how much the image is enlarged, and the standard print size and viewing distance used to determine whether something is "acceptably sharp" ...
  • The general rule was developed along the same lines as depth of field. It depends on the percentage of the full image that the "shaken blur" would occupy, and the degree of enlargement before it ...
  • That is interesting; I have never had a problem like that with B+W filters. However, when I use my Breakthrough X4 filters, I also cannot replace the hood. This is not the norm, and its ...
  • What brand of filter? I have had that problem with a particular brand. Dave
  • You mean that yu can't adjust the VND while the hood is on, or you can fit the hood back over the filter? Dave
  • What is really being said is the image is bring cropped to give the same field of view as if the picture had been taken with a 35 mm focal length in the first place. Determining the amount of ...
  • Gerry, the dpi figures cited are common. The print heads have a different resolution (in dots laid down per inch) capability in the horizontal and vertical directions.  So they are not citing an ...
  • The halos are in the image, not the monitor. A monitor with higher resolution just depicts the halos in more exquisitely fine detail. Dave
