Question: Will this work with film negatives?
Document: After purchasing this product and trying unsuccessfully to get a good image of negatives, I did some research. Color negatives have an amber/orange base film. I don't know about all processing programs, but PS Elements 6.0 cannot quite compensate for this apparently. After processing, images were viewable, but by no means quality. Color and contrast just would not match the actual photo, not even close. Obviously, resolution will depend on the camera you use with this product.
But I thought it would work on 2 1/4 slides and it's for 35 millimeter slides only. If anyone knows a good (not too expensive) way to scan old 2 inch negatives please point me to it.
This is cheap China plastic stuff. My slide duplicator from the 90's for film or full frame dslr's is metal and has a zoom built in to it, much better quality feeling. As stated this slide copier does work (don't expect much for $30), but has issues.
I have given this copier a lot of use both on slides and negatives. It is simple to use and has produced great results.
It is a slide copier, you cannot put regular film in it. It is very heavy and the parts move, very difficult to center the image. A waste of money.
Just as the film copying system previously rated, this too was purchased to record priceless slide film assemblies prior to the Digital Camera era. Was time consuming but worked to archive those precious memories.
For the money, you can't beat the Opteka slide copier. It worked as advertised. I copied several slides made back in the 1960's from a 110 film camera. While the slide frames fit in the copier, the opening wasn't large enough to get the entire image top to bottom. If the detail I wanted was on the very top of the slide, I inserted it into the copier upside down and vise versa. However, slides produced from 35mm film fit perfectly.
This meant that the shutter speed went from a few seconds in good inside lighting (needed more color correction) to 1/30 with outside daylight typically (more/less for darker/lighter slides). Slow shutter speed was not a problem as nothing moves relatively during each shot unless you are careless!I was able to dismantle the slide tray and, using a sharp knife, shave some plastic from one half (and chamfer some edges on the other half) to allow inserting a strip of negatives.
But at least, they must warn the customer about the focal lenght needed for this copier to work properly.
You get what you pay for. It does work but not the best quality. Was able to copy some old slides but was time consuming
Answer: I used a plastic frame I took from a slide, the ones you can open.  then made inverse on photoshop and the result was ok. It gains a particular texture, but it gave the images a unique look.
