Various Photoshop Questions
I had to edit a set of thick cables out of a travel photo, was more complicated than I thought, thus used a variety of tools to clone, heal, and then the vanishing point filter to clone certain areas in perspective. The following questions/issues arose, suggestions will be appreciated: 1) Vanishing Point Filter: if I wish to add a second grid, how do I eliminate the first? 2) Opening the Adaptive Wide Angle filter results in the image immediately being distorted completely out of proportion - why, and how does one open this filter without it in any way altering the image? I was trying to eliminate barrel distortion. I remember in earlier versions ACR had the option to remove barrel/pincushion distortion, but this has been eliminated by Adobe, therefore requires manual work. 3) When using the patch tool, horrible colour smudges not evident in the original area or the patch are introduced. Almost akin to light leaks in a pin hole camera. How is this avoided? Many thanks in advance. |

Hi Matt Could you post a copy of the image? in the meantime you might like to check out this video by Unmesh Dinda of Piximperfect. It might help. http://www.google.co.uk/search?source=hp&ei=JdyOXuGkA-OsgweX1I2ADw&q=remove+wire+fence+in+photoshop&oq=remove+wire+fence+in+photoshop&gs_lcp=CgZwc3ktYWIQAzoCCAA6BQgAEIMBOgYIABAWEB46BQgAEM0COgQIABANOggIABAIEA0QHjoICAAQCBAHEB5KKQgXEiUwZzUwZzQ2ZzQ0ZzQzZzQ0ZzQ3ZzQwZzY3ZzU3ZzUyZzU2ZzU2Sh4IGBIaMGcxZzFnMWcxZzFnMWcxZzFnMWc1ZzVnMTFQxApYz7ABYMi4AWgAcAB4AIABQIgBwguSAQIzMJgBAKABAaoBB2d3cy13aXo&sclient=psy-ab&ved=0ahUKEwihy5H19droAhVj1uAKHRdqA_AQ4dUDCAg&uact=5#kpvalbx=_PNyOXqqeO_CEhbIPl62a8Aw32 _________________  |

Re: Various Photoshop Questions
No 2 to eliminate barrel distortion you don't need Adaptive Wide Angle. Try instead Filter > Lens correction. You will find barrel distortion correction on the tab marked Custom. _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |

Re: Various Photoshop Questions
Forgive me please Matt if I am being obtuse but I don't really understand question 1. You can't add a 'second' grid unless you have a first to attach it to, otherwise it wouldn't be a second. However once you have created the second you can simply select the first and press the delete key. If by your question you mean "How do I delete a grid so as to replace it with a new one?" the answer is basically the same. Select the grid you want to delete and press the delete key. This assumes that you are in the Vanishing Point dialogue. If you are not, open it first and then perform the above. Hope this helps. _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |

3) I am afraid I can't help you with the Patch Tool. I don't like it and so avoid it. There's more than one way to skin a cat and Photoshop is the ultimate example of this. There are often multiple ways to achieve the same end and there is not necessarily a "best" way. "Best" is that with which you feel most comfortable. It might be worth simply attacking your problem from a different direction. I find I can do everything I need in removal and replacement with a combination of Spot removal (which can also remove lines by dragging ), the clone tool, and content aware fill. Good luck. _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |

Re: Various Photoshop Questions
You can also achieve something similar to the Patch Tool by defining a 'source' area with the select tools and creating a 'patch' from it with Layer > New > Layer Via Copy. Drag the new layer to where it covers what you want to Patch and then tweak and blend as required. I do this all the time. It's much more flexible than the Patch Tool. _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |

Re: Various Photoshop Questions
Thanks for the responses GKB and David. GKB: I have seen the video you refer to, no problem per se, it is just that the perspective of the photo really makes it complex (from street level up to roof top). Quick question: what is the maximum size image that can be posted now? David: I use cc2020, just checked under lens cor>custom: gives me exactly the same as ACR option wise. Not really critical, I am just being pernickity. 
The point on vanishing filter answers my question perfectly, sometimes the easiest thing in the world is to overlook the obvious... Great tip on the patch tool idea, will give that a try. The problem with this image is that as the light changes, so does the luminosity as you move along: you'll see what I mean when I post the unedited version. |

Re: Various Photoshop Questions
Hi Matt Open the image, go to Save for Web, reduce size of the longer side to 850 px. Now just reduce the quality slider until it’s 102kb or less then save. _________________ If at first you don't succeed then skydiving is not for you. |

Re: Various Photoshop Questions
Thanks GKB, see the attached image. Both on the ledge above the windows and on the balcony: that railing is a spot of bother, then having to redo the beams on top and finish off the beam on the left hand side. I managed to do all this yesterday, but it took time. No why can't the Spanish be more considerate with their cabling   |

Re: Various Photoshop Questions
Hi Matt I had a bash at removing the wires and this is the result. If the image had been at a higher resolution it would have looked much better as it was difficult to see exactly where to make the adjustments, particularly around the wooden rails so I didn't spend too much time on this part. With the exception of the topmost wire I did this entirely by copy and paste. I started by using the spot healing brush along the top wire but only the part in front of the sky. then I tidied up any small artefacts. This gave me a much larger area of sky to select and copy so that I could expand it over the lower wires. I chose to mask this and then expose only the sky that covered the wires with a very soft brush. The wooden rails were pure copy, paste and re-position with selective masking over the wires. This was the most difficult part but only because of the low resolution of the working image. The rest of the wires were covered by copying the 'dentil' moulding, repositioning and scaling accordingly. that new layer was covered by a mask and only exposed with a soft white brush where the wires lay. The whole thing took just a few minutes. As I said it is not a perfect job because of the low res but it shows what can be done using the old, traditional cut and paste. You should find all this much easier to do with a high res image.

Re: Various Photoshop Questions
If I understand Gordon correctly he has used exactly the copy and cover technique I described as a substitute for the Patch Tool. It really is a very flexible and simple way of hiding things. _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |

Re: Various Photoshop Questions
Thank you very much indeed. Unfortunately the 120 kb restricts what can be done, but I must say I will definitely give the copy & paste workaround a bash. Getting the beams on top correct was a bit of work due to the changing perspective, equally the end piece had to be 'fabricated'. But we live and we learn. Quite frankly, I cropped out the right hand part of the building just before the 'crease', as well as the lower part as neither really contributed towards the image. Which merely leaves the question on why the adaptive wide angle filter distorts the image on opening, maybe I changed a default? As far as barrel distortion is concerned, I can always go back to CS, which is still lurking on my PC. |

Re: Various Photoshop Questions
I have tried opening an image in adaptive wide angle and it opens distorted too. I have no idea why. It is not a filter I use. The correct filter for what you want really is Lens Correction. If when you open the Custom tab your image is distorted check that every single slider is in the centre. that should be 0 for all of them except 50% for midpoint and 100% for Scale. It is possible that the filter is reading camera and lens information from within your file and trying to apply an auto correction in which case it may be pre-adjusting those sliders to its own values. Make sure they are set as described above as your start point and then adjust from there. When the sliders are set as above you should be seeing your original image exactly as shot; with of course any inherent camera/lens distortion such as barrel or keystone visible, ready for you to correct. Without seeing things first hand it is very difficult to guess what is happening. But do try the above please Matt. _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |

Re: Various Photoshop Questions
Thanks David. Methinks the AWA filter issue arises as I use a Pentax camera with a Sigma lens, which is not automatically recognised. When I then hit the Sigma lens button, it immediately recognises it and gives me no grief. As for barrel distortion, in those seldom cases where it is a problem, I can either use the split warp or quickly jump back into CS6. Many thanks for your help, really appreciated. |

Don't worry David, I have learnt that often in life the "Heath Robinson" approach works minor miracles.... |
