Inverting negative film strips in LR5?

[AlaskaAce]

I do invert negatives it in PS CS6 and was wondering if LR5 has that ability?

[D.A.R]

You can use the Tone Curve to invert images.

Click the icon to enable Point Curve editing. Drag the corner points to their opposites.

[AlaskaAce]

Thanks David.

Seems so simple once someone points it out.

If you have a lot of these to do you can save that Tone Curve as a Develop Preset. Then it can be applied with a button click. Or to many images at once via the Quick Develop panel.

Good point Rikki, thanks for the tip, I do have a bunch of film strips. I shooting them in RAW on my 5D M2 with a DYI setup so far I'm getting good results. I hsve PS6 but am thinking LR5 is more suited for my work.

Apparently, Custom Point Curve is no longer available in LR 6.5

[Per Berntsen]

Yes it is. Just click the icon and adjust the curve.

The word "Custom" doesn't appear until you start manipulating the curve.

What icon? Also, I can't select RGB, it only has contrast adjustments. Using Lightroom 6.5 (NOT CC)

See reply #1 in this thread.

OK, got it, the little curve icon. Thanks. I have been able to convert a film color negative (shot using a digital camera, bellows, macro lens, and slide duplicator) to a positive image in LR. And saved it as a preset.

Good catch by Per.

You need to click the icon so that the sliders are not shown. Then you can move the endpoints.

Nice, and works.  But the picture is blue. 

[Rob_Cullen · Accepted solution]

But the picture is blue.

When you invert the (negative) image of a Color negative, you also have the base color of the film to worry about. Color neg film has an orange base.  Inverted it becomes blue!

For B&W monochrome negatives  just inverting the tone curve is acceptable. Color negatives need a lot more work.

Inverting the tone curve in Lightroom, also has the side effect of reversing several of the Basic Develop sliders! which can be a surprise. If you make a preset of an inverted tone curve you can also modify it to include contrast (the traditional "S" curve)

I plan on buying a professional scanner now.  Less work.

[JP Hess]

That is a good choice. I believe scanning with a quality scanner produces a much better image.

What can be recommended ?

I once had a 35mm negative scanner that actually scanned the negatives and produced very

high quality results.

There is a misnomer in the modern description 'scanner' because they all appear to be just a camera

in a box.

With and old 'camera' model I removed the base and used it to copy medium format negatives placed

on a light box.

It is strange that manufacturers have not worked out that this can be done and produced a

convertible 'scanner'.

It's dumb that there isn't a simple invert checkbox.   You can invert the curve, but then shadows are highlights and it's pretty confusing to work with.  

I'm capturing my negatives with a DSLR and it gives results at least as good as a flatbed scanner, and it's so much faster than scanning.   More and more people are working this way as full-frame DSLRs have come down in price.
