Hello Everyone,
I need some of your expert advice. I have some more Grumman photos (maybe a 100), the problem is they're 4x5 and 2x4.5 negatives. Do any of you have any ideas on how I can convert them to positives? I have a scanner and Photoshop if that helps. Thanks ahead of time.....AJ

Something like this? I did a quick import into GIMP - which is a free open-source program, left clicked to the "Colors" menu, did "invert," and then tweaked it just a bit with "Curves."
And yes, I'm bored today with no students at the airport...

where is this in Photoshop??? I have a early version......

How's that ?
IRFAN view (free software); effects, negative, color corrections, sharpen (which I overdid a bit).

Not sure what pitch the prop is in for installation, but the photo might be backwards.

I think it is backwards, and thanks everyone.........

I have no idea, sorry.

try Ctrl A
That will select the entire image, then
Ctrl I
That should invert it.

Before getting all wound into this post-process stuff, can we check the images were scanned while backlit, or is it a scan using the positive setting? Given negs are emulsion on film, you'll get an OK tonal range from a positive scan, but nothing like what they'll yield if scanned as they were intended to be used, with backlighting.
My scanner has a backlight (film) option with a light in the lid and trays for film and negs, but unfortunately, like most, it'll only do 35mm, rather than large format. You may be better to get someone in a photolab with the large format carrier setup to scan them properly, rather than trying to recover from a bad starting position.

When I first looked at that pic of the Hellcat, I thought "wait, that left landing gear is on backwards!" Then I realized it belongs to the next plane in line, and the left gear is blocked by the "Rosie" in the foreground.
