jammer_jammer Posted October 1, 2006 Share Posted October 1, 2006 Attached is a sized down gif animation of my first flare problem with my new Nikon V ED scanner and then the subsequent quicky fix with PS Elements.<p> I've scanned 80 some slides thus far. I've seen this issue raise it's ugly head a total of 3 times but in the first two instances, I was experimenting with using the "Positive" setting on the scanner even though the slides were Kodachrome 64. When I would switch it back to the Kodachrome setting, the flare would go away completely. This is the first instance where I got the flare even on the Kodachrome setting. It's completely obvious on the little girl's right arm but what really weird is there is actually some flare on the left arm also, where the contrast is much less.<p> Since it happens so infrequently and I'm able to do a half decent fix with Elements, I don't think I will be sending the scanner back. I'm not really sure what else I would buy anyway. I don't want to spend any more and I don't want to buy Minolta since they are defunked as this point. I did want people to know that this is a real issue on occasion though. :-( Link to comment Share on other sites More sharing options...
jtk Posted October 2, 2006 Share Posted October 2, 2006 Nice shot. The original version of the scan (with flare) appears to have too little saturation and contrast in the face...it doesn't look like what I'd expect from properly exposed chrome. I wonder if the problem began in the film (perhaps use of a filter?) rather than the scanner. I doubt you could see it with a high powered loupe. Try 4X, not 8X.

Tim_Lookingbill Posted October 2, 2006 Share Posted October 2, 2006 If you're using the same settings to scan all 80 slides without checking endpoints for each scene as a kind of one size fits all automated process, you're bound to run into flare up inconsistancies due to varying exposures at the time the shots were taken by the camera. Not sure of your workflow or setup. Just a guess. Do you have a locked down max endpoint setting to be applied to all 80 slides that doesn't allow blown highlites or absolute blacks, so you have something to work with in PS? I have yet to see any consumer scanner where you can get perfect shots without any editing. That flare looks like too much light by the scanner or sensor gain due to not controlling highlite blowouts within the software. Link to comment Share on other sites More sharing options...
jammer_jammer Posted October 2, 2006 Author Share Posted October 2, 2006 John,<br> "it doesn't look like what I'd expect from properly exposed chrome."<p> Yeah, unfortunately, I'm finding out that the vast majority of my slides are not "properly exposed", well, at least not for scanning anyway. They look fine projected but I had routinely underexposed for saturation and almost all of my scans are originally scanning WAY to dark. I've got to really work every scan. As far as there being any flare in the slide itself, I couldn't say as I don't have a lope or a light box as of yet. Thanks John.<p> Tim,<br> Because I really need to work almost every slide, my original preview is always with no adjustments whatsoever so that I know what I'm dealing with. I work each slide individually. As far as my work flow, well, I've tried all kinds of things. I push buttons and sliders and make settings until things look better. LOL. The most recent work flow pattern that has started forming is to look at the raw preview in order to decide how much analog gain will be needed. I fiddle with the gain a few times until I've brought out as much as possible without blowing highlights too badly. Then I usually go to curves and use that whitepoint dropper icon thingy to set a white point, which I found out, by experimenting, seems to be the easiest, fastest way to get the colors where they look the most natural to me. That's usually the point where I scan. Any further fine adjustments I make in elements. I have no idea if this is even close to a logical work flow. It's just sort of what I have come up with after 80 scans.<p> "Do you have a locked down max endpoint setting to be applied to all 80 slides that doesn't allow blown highlights or absolute blacks, so you have something to work with in PS?"<p> I have nothing locked down at this point and don't completely understand what you are saying. Could you please explain exactly what you're saying and how I would go about doing this?<p> "I have yet to see any consumer scanner where you can get perfect shots without any editing. That flare looks like too much light by the scanner or sensor gain due to not controlling highlight blowouts within the software."<p> You could be on to something because I do end up having to use some degree of analog gain on almost every shot. Should I "control the highlight blowouts BEFORE using the analog gain? If so, could you please explain exactly how to go about this. <p> To both of you, I guess what would be really helpful to me would be for you both to go into what your typical workflow is, including any permanent settings you may use. Then I could experiment with your workflows and ask questions about any of the steps in your workflow that I do not fully understand.<p> THANKS GUYS!

I have nothing locked down at this point and don't completely understand what you are saying. Could you please explain exactly what you're saying and how I would go about doing this? ---------------- I think he's just asking if you are varying the exposure to suit the slide (not clipping the highlights or blocking up the shadows on some slides) and the answer seems to be "yes." You can check this on the histogram- with slides, try to expose as far to the right as you can without blowing out highlights or introducing flare.

Tim_Lookingbill Posted October 2, 2006 Share Posted October 2, 2006 I'm not familiar with Nikon scanner software so I don't know of anyway of locking endpoints to be applied to each frame. I have Epson Scan to scan negatives. Negatives are a real pain for me as it is for others from what I've read on numerous posts on the subject. The reason I believe is mainly from having to rely on memory as to how the image should look. Also establishing a realistic depiction of outdoor color temp has been a real challenge for me so I really haven't been able to develop a viable and fast workflow. I certainly haven't been able to scan 80 frames like you, so I was hoping you could teach me a thing or two. But what I've come up with is once I get one frame looking correct, I can save the setting and apply it to other frames on the same strip, but it's a little like starting over because one color temp correction for one scene doesn't look right for another taken later in the day or under a shade. So there's never an automated process to my workflow where I can just crank it out like my local one hour minilab. But they don't give me a realistic or accurate results either. That's what I meant by locking down established tolerable brightness levels by first setting your spectral highlites=(255 RGB) which should only be applied to sun shining on water or shiny surfaces, not on people's arms and clothing. The thing is once 255RGB as been established in spectrals it's quite easy to keep brightening past this point with further curve/levels edits thus causing flare ups from blasting light on the sensors. I can intentionally cause flare ups on my negatives by adjusting the Epson Scan levels highlite slider farther to the left after already establishing spectral highlites. Here's a screen capture to show what I'm talking about. Link to comment Share on other sites More sharing options...

Negatives are quite distinct from Jammer Jammer's slides in this respect. I'd suggest you make your default settings for mid-day sun (essentially neutral for daylight color films) and then your other shots with deviate from it in a predictable way (cloudy shots will look cooler, fluorescent greener, etc). Consider a QP card (white, black, gray) to help you with this- it's cheaper than most alternatives. Link to comment Share on other sites More sharing options...

stan_belyaev Posted October 3, 2006 Share Posted October 3, 2006 I had the same problem with nikon 5000. The only solution I was able to find was to sell Nikon and to buy Minolta Multi Pro. Link to comment Share on other sites More sharing options...

robert_k1 Posted October 12, 2006 Share Posted October 12, 2006 Jammer, IMHO your PS fix is acceptable in this image, to a degree. The top part of the image has a background without any details and the fix is fine. But fixing the bottom part loses all the details (which may not be important in this case). In many other images with critical details in the background, I would find such a fix unacceptable. This drove me crazy on my old scanner. After purchasing a Minolta 5400, I have not seen flares since.
