barjohn Posted July 3, 2007 Share #1 Posted July 3, 2007 Advertisement (gone after registration) I have LR 1.1, Bibble Pro, and Photoshop CS3, what I lack is knowledge on how to effectively remove a moire pattern in a black tux in a wedding photo caused by the lack of an AA filter. I have read here before that there is ways to do in post processing but I can't figure out how to do it. Any help please? See image below and look at left (his right) part of suit and lapel.

sisoje Posted July 3, 2007 Share #2 Posted July 3, 2007 His tuxedo??? I am more worried about her chest veins... Be sure to remove those too,before you show the image to the clients.... Good luck. Quote Link to post Share on other sites More sharing options...
barjohn Posted July 3, 2007 Author Share #3 Posted July 3, 2007 She's used to those showing as she is a busty gal but the tux...ah..that is another story. Quote Link to post Share on other sites More sharing options...
AlanG Posted July 3, 2007 Share #4 Posted July 3, 2007 I don't know if any software would completely remove that moire as it has a black and white component overlayed with color. I played with it for a few minutes and here is a crude job as an example. I used a desaturation brush to remove the color and then I used a paint brush to add gray and black (where lighter.) I also removed the chest veins. Did they really look like this in person? If there are many images like this, you may have a lot of retouching to do. Good luck Welcome, dear visitor!

lxlim Posted July 3, 2007 Share #5 Posted July 3, 2007 John, Photoshop: Use brush. Set foreground colour black or use colour picker to pick up the tux's colours. Change the mode to from "Normal" to "Colour". Paint over the tux. You may need to mask off the lady's face to avoid any bleeding of colours.

robertwright Posted July 3, 2007 Share #6 Posted July 3, 2007 you could also take the right lapel and layer it over the left, with some finesse and a layer mask it would be seamless. You can also control the brightness of the lapel independently. Quote Link to post Share on other sites More sharing options...
sdai Posted July 3, 2007 Share #7 Posted July 3, 2007 Advertisement (gone after registration) You should try C1, John. Phase One is pretty good at dealing with moire. Quote Link to post Share on other sites More sharing options...
barjohn Posted July 3, 2007 Author Share #8 Posted July 3, 2007 I just opened the image in C1 and it looks better than LR or CS3 but I don't see any way to make adjustments or make it better. Do you need the pro version for adjustments? Quote Link to post Share on other sites More sharing options...
AlanG Posted July 3, 2007 Share #9 Posted July 3, 2007 I just opened the image in C1 and it looks better than LR or CS3 but I don't see any way to make adjustments or make it better. Do you need the pro version for adjustments? C-1 does not have any type of moire removal tool although I have noticed that it suppresses moire to some extent compared with another raw converter that I use. The pro version of C-1 comes with a Photoshop plug-in for moire removal but I've never used it. I don't know if this comes with C-1 LE. It's worth a try, but I think in this case, the moire is so prominent that you'll have to retouch. Do you have a number of images wiht this problem? It should only take a few minutes to retouch the black jacket if you have only one shot with this problem.. I don't use Photoshop so I can't give you the specific terms used in that program. First select the jacket to mask it from the other objects. Then use a desaturation brush to remove color. Then paint in some black and gray using a fiar amount of transparency.

sdai Posted July 3, 2007 Share #10 Posted July 3, 2007 C1 already has moire filter built in inside the raw engine ... also if you don't use C1 to convert your files, you can choose to install Phase One's moire filter as a Photoshop plugin when you load C1 on your computer, then you can find it in CS2 or CS3 going to Menu -> Filter -> Phase One A/S -> DeMoirize.

AlanG Posted July 3, 2007 Share #11 Posted July 3, 2007 I believe the moire tool in C-1 Pro is only on the Mac version and only works with Phase One backs. I think the DeMoirize plug in comes with only the Windows version of C-1 LE (and pro versions for Mac and Windows.) But I'm not sure as the site is a bit confusing. People are hoping a lot of this is cleared up on C-1 version 4.

barjohn Posted July 3, 2007 Author Share #13 Posted July 3, 2007 I down loaded the Pro version and installed the demoirize plugin tool but it has an error when loading in CS3 on the Mac. I haven't found anything else. I thought I remember reading a while back that moire was not a problem with the M8 because an AA filter could be applied after the fact to images or parts of images in CS. Now I have to wonder.

I used a B&W filter. The veins are that way in real life. She has very translucent skin and they are plainly visible to the naked eye. While I don't find them unattractive others may. As I said she is very busty, tends to wear low revealing tops and the veins have always shown so I don't think she finds them objectionable. However, I can ask her when she gets back and remove them if she would like. Quote Link to post Share on other sites More sharing options...
sdai Posted July 3, 2007 Share #15 Posted July 3, 2007 I don't use a Mac for now so I can't confirm ... but I suspect the DeMoirize plugin is one of those things still not fully adapted to CS3. Quote Link to post Share on other sites More sharing options...
barjohn Posted July 3, 2007 Author Share #16 Posted July 3, 2007 Artichoke, I could not follow your instructions in CS3. I guess I am dense on this one as it is not intuitive as to where one selects: Set current layer Or to, mode, etc. I just don't see anything like that.

ChrisC Posted July 3, 2007 Share #17 Posted July 3, 2007 John - You are lucky because the moire is on dark, fairly mono-toned material, therefore repair is easy: In Photoshop, on a duplicate layer, use the Eyedropper Tool [it's in the tool palette], take an accurate colour sample of the area to be repaired. Select Paintbrush [from the tool palette] and set it's Mode [at the near-top of your screen] to Colour. With Opacity [also at the near-top of your screen] set to 100%, paint the moire. You might also use that layer's opacity slider to reduce back it's % opacity [try 50%] before layer merging; you might retain more 'texture' this way. If you know how to 'Feather' the repaired area before Layer merging; do so. Easier to do than to describe. Good luck. Those veins are really impressive, did you use an IR filter on the lens? If not, you might wish you had. ...............Chris Quote Link to post Share on other sites More sharing options...
barjohn Posted July 3, 2007 Author Share #18 Posted July 3, 2007 Chris, I used an IR filter. See my prior post #14. When you are quickly shooting and only chimping on occasion you can miss seeing this to take a corrective shot. I was using fill flash too so that may be part of it. I was trying to stay out of the way of the professional photographer hired by the couple and I was grabbing shots as I could. All were shot with a Minolta 40/2 with a B&W UV/IR filter.

I thought I remember reading a while back that moire was not a problem with the M8 because an AA filter could be applied after the fact to images or parts of images in CS. Now I have to wonder. The DeMoirize plugin works on Windows with CS3 (at least on my machine). I just used whatever default settings came up and didn't really play with it and it seemed to help quite a bit. I think AlanG's technique did a better job. Has anyone else got it working on a MAC? Welcome, dear visitor!
