A CanoScan Scanning Guide – Part 3: Cross Processed Slide Film

This is a how to guide for anyone struggling with their CanoScans. This is for Cross Processed Slide Film and the third installment for my tipster. Read on!

Switch your scanner on and get it set up to start scanning your film (Refer to Part 1 for details).
Now that you are set up to start scanning your film follow the next step for cross processed slide film scanning.

Cross Processed Slide Film

Slide film or colour reversal film is film with high contrasts especially when cross processed, this means that instead of developing it in E6 you develop it in C41 and your negatives become negative not positive.
There are 2 ways to scan Cross processed slide film and they will both give you different results and colours – so try both out and see what you prefer.

Scanning Option 1

First place your film in the scanning mask and select preview (the blue button at the bottom). Then use the selection tool to adjust the borders of your images as the scanner does not understand spinner photos for example so you will need to make the selection larger. When scanning any images with sprocket holes make sure you do not select over the sprocket holes in the beginning only select the centre image to work on, I will explain in a few steps. Your settings are as follows:

Input Settings
Select Source: Monochrome Negative Film/ Colour Negative Film – play around with both depending on what you like
Scan Area: Auto Detect
Color Mode: COLOR – make sure you select colour not grayscale otherwise that is exactly what you will get.
The dimensions setting should be set already and I work in mm.

Output Settings
Output Resolution: This is really up to you, I work at 1200dpi as a general unless I need very high resolution (bear in mind the higher the dpi the longer the scan will take)
Output Size: Flexible, dimensions should once again be set and at 100%
Data Size: This changes according to your settings – you don’t change it, it is there to let you know how big the file will be.

Image Settings
Image Adjustment: Photo
Unsharp Mask: On
Remove Dust and Scratches (FARE): None
Fading Correction: None
Grain Correction: None
Backlight Correction: None
Exposure/ Tone Settings – press the down arrow for more options
Manual Exposure: Here you can alter the exposure of your images before scanning by ticking the box. The higher you make the percentage the less exposed the image becomes and the lower you make it the more exposed it becomes. Apply the tone value to all crops.

This apply button is crucial when scanning sprocket holes, if you make a selection with sprocket holes you will see that your image becomes washed out and over exposed, so as I mentioned earlier edit your images without the sprockets selected when you are happy with your result press apply and it will save your settings and you can then stretch your selections to include the sprocket holes and you will see your image remains the way you liked it.

High Quality: Off
You will see a range of picture buttons at the bottom that deal more with levels, curves, saturation, etc – use them if you need. Now you are ready to scan your cross processed slide film so press the green scan button.

Scanning Option 2

This method is far more time consuming however I generally prefer the colours I get. You will need a strip of ordinary colour negative film for this. Make sure you choose a well exposed one that is not over or under, do not use coloursplash photo’s or photo’s taken with a flash or mask. Your best bet is a daylight photo, shot with 400 iso film.

First place the colour negative film strip in the scanning mask and select preview (the blue button at the bottom). Then use the selection tool to adjust the borders of your images as the scanner does not understand spinner photos for example so you will need to make the selection larger. When scanning any images with sprocket holes make sure you do not select over the sprocket holes in the beginning only select the centre image to work on, I will explain in a few steps. Your settings are as follows:

Input Settings
Select Source: Colour Negative Film
Scan Area: Auto Detect
Color Mode: Color
The dimensions setting should be set already and I work in mm.

Output Settings
Output Resolution: This is really up to you, I work at 1200dpi as a general unless I need very high resolution (bear in mind the higher the dpi the longer the scan will take)
Output Size: Flexible, dimensions should once again be set and at 100%
Data Size: This changes according to your settings – you don’t change it, it is there to let you know how big the file will be.

Image Settings
Image Adjustment: Photo
Unsharp Mask: On
Remove Dust and Scratches (FARE): None
Fading Correction: None
Grain Correction: None
Backlight Correction: None
Exposure/ Tone Settings – press the down arrow for more options
Manual Exposure: Here you can alter the exposure of your images before scanning by ticking the box. The higher you make the percentage the less exposed the image becomes and the lower you make it the more exposed it becomes. Apply the tone value to all crops.

This apply button is essential for this method of scanning, once you are happy with your settings press APPLY. Now remove the colour negative strip and place your cross processed film in the scanner and press preview again. You will see your colours are brighter and very contrasted. You can now scan your images. Do not reset your tone values unless you need to adjust exposure – this is where the time comes in as you will need to rescan the colour negative strip and adjust the settings then apply and change films again – however it is worth it for certain images but not for others – you will just have to see as you go.

The apply button as mentioned previously is also crucial scanning sprocket holes, if you make a selection with sprocket holes in your colour negative film you will see that your image becomes washed out and over exposed, so as I mentioned earlier edit your images without the sprockets selected when you are happy with your result press apply and it will save your settings and you can then stretch your selections to include the sprocket holes and you will see your image remains the way you liked it.

High Quality: Off

Now you are ready to scan your cross processed slide film so press the green scan button.

SOME OTHER GENERAL RULES:

  • Save you photos after each roll scanned as the software can crash- doesn’t happen often but it has happened once to me and it is annoying.
  • Always clean the scanner before scanning to avoid hairs and dust – I clearly forget to do this often if you look at some of my oh so dusty photos!
  • Last but not least EXPERIMENT – there are many little buttons to play with so see what works for you, you never know what you may come up with.
