Exodies Posted July 6, 2017 Share #1 Posted July 6, 2017 Advertisement (gone after registration) Well, first one I've printed and framed. Hanging temporarily (Madam tells me) in my house. Several things strike me: The picture (of the pictures) was taken with M type 240, Summaron-M 1:5.6/28 and shows lots more vignetting than I have seen previously. I used UV filtering glass and all highlights reflected in it are purplish. The source of the highlights are daylight outside. The colours of my photograph (within the photograph) don't look right, but they do when I look at the picture on the wall - here it is (as I expect to see it) in my gallery gallery_35907_5530_132670.jpg Any ideas about these last two points?

Michael Geschlecht Posted July 6, 2017 Share #2 Posted July 6, 2017 Hello Exodies, Nice photo. You might consider getting a polarizing filter such as a 13352 if your lens takes an A42 lens cap. This allows you to preview the effect of the filter thru the range/viewfinder of an "M" camera. If the lens is not that size there should be some other available that will do more or less the same thing. Years ago there were also numbered polarizing filters available. These had a series of numbers on the edge of the rim. You would look thru the actual filter itself & rotate it until you got the effect you wanted. Then you would look down from above & see which number, or between which numbers were at the top. Then you would attach the filter to the lens & then rotate it until the same number, or between numbers were on the top. This might also help to deal with the violet in the glare.

Jeff S Posted July 6, 2017 Share #3 Posted July 6, 2017 I'm confused. Are you saying that the print looks as intended out of frame? (If not, why frame it?) There are many issues that can contribute to unsatisfactory print quality... from capture through final editing and printing. If, however, the problem occurs only after display under glass, then problems can relate to the glass as well as the lighting ( in conjunction with the paper and paper profile). What type of glass, or plastic, are you using for cover? Glare resistant? UV protected? Jeff Link to post Share on other sites More sharing options...
Luke_Miller Posted July 6, 2017 Share #4 Posted July 6, 2017 I think the color in the reflections is due to the different color temperature of the outside light. Link to post Share on other sites More sharing options...
Jeff S Posted July 6, 2017 Share #5 Posted July 6, 2017 I think the color in the reflections is due to the different color temperature of the outside light. That's one reason why I asked for clarification. Light temp can be accommodated at print/profile stage and/or with changes to lighting or cover materials. But I'm not sure he's satisfied even before display. Jeff Link to post Share on other sites More sharing options...
Exodies Posted July 6, 2017 Author Share #6 Posted July 6, 2017 The print has the colours I want, before framing and after framing under UV protective glass - I'm happy with my print. What I can't understand is the photo of the photo. I think Luke may have the answer to my third point ("The colours of my photograph (within the photograph) don't look right"), there is daylight coming through the door on the right and in the room behind the camera there are LED lamps and halogen lamps burning. I'll take another shot tomorrow using only daylight. This problem to be addressed tomorrow. For my second point ("I used UV filtering glass and all highlights reflected in it are purplish") however, the picture on the right, which I think has ordinary glass, shows daylight reflections in natural colours. This is the outstanding issue. Michael - I agree, I should use a polarising filter to make a good photograph of my hanging picture, but this was just a snapshot to present my finished framing to the world (the forum) because no one is going to see it otherwise. I was a bit concerned about the UV protective glass when I saw the strange reflections of highlights but I placed it over half of the photo and it isn't doing anything to the picture's colours. These two colour checker shots have had the colour temperature set manually to 3800 (I think that should show up any effects the glass has). The first one is under the UV glass, the second one is not under glass. They look the same to me but my vision is low-fi. Welcome, dear visitor!

pop Posted July 6, 2017 Share #7 Posted July 6, 2017 Advertisement (gone after registration) ...I used UV filtering glass and all highlights reflected in it are purplish. .... Do the reflections look purplish in a photograph of the frame only or do you see the purplish reflections by naked eye as well? In either case, do you see purplish reflections when using only the glass of the frame without anything at all in the frame? I rather think you might be seeing the effect of some coating, similar to the purplish reflection from the IR/UV blocking filter used for the M8.

Jeff S Posted July 6, 2017 Share #8 Posted July 6, 2017 Likely anti- reflective glass coating. Purple reflections happen with some eyeglasses for that reason. The uncoated glass has no such issues. Jeff Link to post Share on other sites More sharing options...
Exodies Posted July 7, 2017 Author Share #9 Posted July 7, 2017 The reflections are purple with naked eye also, and appear with or without a picture behind the glass. Must be the coatings. Does that mean there is a right side and a wrong side for facing out? Another test to do today. Link to post Share on other sites More sharing options...
erl Posted July 7, 2017 Share #10 Posted July 7, 2017 Reflections in glass are a fact of life. Learn to live with them. Sometimes, by judicious placement/hanging, you can reduce them. (eg. not opposite a window if you can avoid it. Difficult I know.) Non reflective glass, in my years of experience, significantly degrade the image quality and I will never use it. I just put up with the reflections, by moving my feet sometimes. An additional thought re. photographing your display. Use a polarizing filter on your lens AND polarizing gels on your light source. Eliminate ambient light as much as you can. Link to post Share on other sites More sharing options...
pop Posted July 7, 2017 Share #11 Posted July 7, 2017 Question is, why did you use UV protection glass? That's usually used to keep original works from fading away. In your case, non-reflecting glass might be the better choice, even if it's a bit more expensive. Modern non reflective glasses do not visibly degrade the image quality, as far as I could see. Look for the quality that's called "museum glass" or some such. That's a far cry from the matted or ground glass panes they used in the sixties or eighties. They are a pain to keep clean, though.

Does that mean there is a right side and a wrong side for facing out? Another test to do today.Yes, good art glass is marked "this side faces art work", or something similar. I stock different glass from Tru-Vue, typically both their Conservation Glass and their Museum Glass, for different needs. I buy them in bulk from a local glass company in sizes to match my matting and frame supplies. That way they cost a fraction of retail cost through a frame shop. Glass varies greatly in construction and quality. And there are plastics, which have other advantages and disadvantages. Always best to experiment under actual lighting conditions before committing to bulk. Light transmission is another factor that I consider. Prints often look different under glass, especially subtle b/w tones that can lose 'sparkle''. This needs to be accommodated through exposure at the PP stage. Glass.... and framing and lighting...are important parts of the print workflow, often overlooked. Jeff Link to post Share on other sites More sharing options...
Exodies Posted July 8, 2017 Author Share #13 Posted July 8, 2017 I used UV protective glass for protection and also because at my frame shop this glass is advertised as having anti-reflection properties. I re-photographed the hanging picture with daylight only and using a measured white balance. The daylight is softer than previously. The result is much more satisfactory. The picture's colours are correct. The UV glass demonstrates it's anti-reflection properties too; compare with King Louis under plane glass. I can't see a difference with the glass one way round or another. Welcome, dear visitor!

Michael Geschlecht Posted July 8, 2017 Share #14 Posted July 8, 2017 Hello Exodies, The 2 cover glasses are at different angles to the axis of the lens. You might look into polarizing filters if you plan to take more photos of this type. This is 1 of the situations that they are most used for.
