Convert a negative to a positive. Ideally, you would shoot your slides and negatives in a Camera Raw format and edit the photo in the Camera Raw converter. Unfortunately, Photoshop Elements doesn’t provide you with an opportunity to convert the negative to a positive image in the Raw Converter. Convert Negatives to Digital Photos: For years I have been trying to find an economical way to convert negatives and slides to a digital format, especially those in an older larger format. The scanners available for these large format negatives and slides are out of my price range.

Creating a negative in Microsoft Paint

Note

The following step is crucial. Steps five through eight do not work without turning on the Magnifier.

  1. Next, open the Windows Magnifier by pressing Windows key and the =. Make sure the magnifier percent is set to 100. Also, ensure Full screen is selected under Views.
  1. Now, invert the colors of your screen by pressing Ctrl+Alt+I (Ctrl key, Alt key, and letter I key).
  2. Take a screenshot of your inverted screen by pressing the Windows key and the prtSc (often named PrtSc or Prt Scrn on the keyboard) at the same time. Using the Windows key+prtSc shortcut automatically saves this screenshot to your Pictures folder.
  3. Once you've taken the screenshot, you'll need to revert the screen back to its normal coloring by pressing Ctrl+Alt+I again.
  4. Close the Windows Magnifier.
  5. To open the inverted picture, open the Pictures folder on your computer. Then, open the Screenshots folder in the Pictures folder and find the inverted picture as a thumbnail. Right-click on the image file, select Open with, select your browser, and click OK. Your image opens in the browser window.
  6. Next, you need to use the Windows Snipping Tool to crop your picture to the desired size and look. Click Start or press the Windows key, type snipping tool, and press Enter.
  7. Click on New in the toolbar, resulting in your screen looking foggy and your mouse arrow cursor changing to a cursor.
  8. Left-click and drag the cursor around the inverted image to the desired size. Once you let go of the left mouse button, the Snipping Tool window appears again, containing the cropped image only. You can now save the new, cropped image to the desired location on your computer.

You now have a negative of your original image, like the example below.

Last week I showed you how you can use just a DSLR and a few accessories to digitize your negatives. However, that article wouldn’t have been complete without explaining how to convert the scanned analog picture to a positive image. The process is quite easy and only a few steps are required to achieve a great result. Let’s dive in!

Why Use Capture One?

As the title indicates, we are going to use Capture One to make our positive image come to life. The reasons why I prefer Phase One's raw converter software for this process are the following:

  • Unlike Photoshop, Capture One works on the raw file created using the technique shown in my previous article, and thus leaving a bit more room for adjustments without losing quality.
  • Unlike Lightroom, Capture One has both curves and levels tools, avoiding to mix the color correction and the negative to positive conversion process.
  • Capture One has a powerful tethering tool that can apply a style to convert the negatives on the fly while digitizing them, thus saving a lot of time.

With that being said, the method shown in this article, and video above, can be used in any app that offers either a curves or levels tool. Be sure to try both Capture One and your current photo editing software of choice, and see for yourself what’s best for you.

Turning a Negative Into a Positive Using Levels

Mac Software To Convert Negative To Positive Images Of

In Capture One, open your Levels tool (Window > Create Floating Tool > Levels). In a negative picture, the black point is actually white and the white point is black.

To make it a positive, we want to invert that and indicate to Capture One that the black point has a value of 255 (white) and the white is 0 (black).

If you are working with a software that doesn’t have levels, you can do exactly the same by inverting the RGB curve like so:

As you can see, curves and levels can achieve the same result. In both cases, my negative ends up with a noticeably strong blue color cast. Depending on the film, the chemical process, and the scanning gear you are using, you might have a different color shift than blue or perhaps none at all. But if you do have a color cast like I do, don’t worry, there is an easy fix, and it will work no matter what your current positive looks like.

Color Correction

Let’s bring our white balance tool and select the white balance picker (press 'w' on your keyboard to access it quickly). Including the border of my film in my scans finds its reason here: it gives me a neutral area to sample my white point from. So by simply picking from the border of the film with my white balance color picker, the blueish cast should mostly be corrected as you can see here:

Obviously, it still doesn’t look quite perfect. But now we have a positive image that we can edit just like we would on any other picture — or almost. Don’t forget your raw file is a negative, so some sliders will work the other way around than what you are used too. For example, pushing the exposure will give you a darker positive image, while pulling it will yield a brighter picture. Before yelling at your computer because it doesn’t do what you ask for, be sure to try to push or pull the slider to the other side and see if that achieves what you are looking for.

Getting Lab Quality Color Correction

As we shot the negative in raw, the correction can almost be pushed as far you’d like to. You could decide to go for something rather neutral:

But because we shot a color film, doesn’t mean we have to use it as a color picture:

Now, if you want to get perfect color correction, something very similar to what you would benefit from a lab scan, I would recommend you to send one picture to a lab from each film stock you are using. Once you get your digital file from the lab, digitize your file with your setup, and try to color match you picture to what the lab sent you.

The first time I digitized a negative, I created the following positive image out of it:

Then, when I received my scan from the lab, I worked on it again and it looked something like this:

The Power of Presets

From there, I created a preset that I could apply to future captures of Kodak Portra 160 negatives. To create a new preset, go to the Adjustments tab and under Styles and Presets, or access it from Window > Create Floating Tool > Styles and Presets. Click the '+' button next to the drop-down list and check every setting you want to include in your preset (avoid including exposure, crop, local adjustments, and other settings that can vary from image to image), then click save, give it a name, save again and your presets is now created.

C# Convert Negative To Positive

From now on, if I shoot with my camera tethered to my computer with Capture One open, I can apply this style on the fly, and watch the positive image appear on my screen without having to do anything. All I have to set is the Styles setting in the Next Capture Adjustments tool that can be found in the Capture tool tab.

As you can see, the process isn’t very complicated. All you have to remember really is to invert the RGB levels or curve and then color correct the image with the tools you like best. Shooting raw, I would suggest starting with the white balance tool like shown in this article, and then use either the color balance tool or the curves to further refine it. If, for some reason, you are stuck with JPEG or TIFF negatives, you may want to skip the white balance tool altogether and give the curves a try.

If you have the possibility of shooting tethered, don’t overlook it. It will allow you to zoom in on the files and be sure everything is in focus, that you don’t have any Newton rings showing, or too much dust on your negatives. Also, it’s a great way to check you exposed your digital capture correctly to get the best out of your precious analog picture.
