Image processing techniques

Jane Fonda and Me... A print from previously unseen photographs taken on the set of the making of Barbarella in 1967 - points out how producing prints from scanned film needs different techniques to images from digital cameras.

Producing a black and white print
An article describing the full process Keith went through in producing a black and white landscape print. From taking photographs, through editing the image and final printing. Includes a downloadable version of the original colour image as an example to work on. [May 09]

Why use RAW format
Does your camera have a raw format for saving images? All about what it is and why you should use it.

Convert your 8 bit RGB images to 16 bit
- before converting to black and white?
If you are going to be doing much in the way of image manipulation (curves etc) to your black and white image, it -may- be better to convert your 8 bit colour images (such as JPEGs) into 16 bit colour first. Sometimes 8 bit RGB can be equivalent to 10 bit greyscale.

Pictures at an Exhibition
Keith has written an article about some of the technical image processing and resizing issues that he came across when producing 29 prints (up to 78"x43") for a large exhibition of his landscape work (mostly digital images, but some from scanned film). One more reason he's glad to have the original RAW files to go back to if need be. There is a link to the exhibition page showing versions of all the images exhibited.

Resampling to make your images bigger
Never be afraid to go back and re-evaluate your workflow. There is nothing wrong with changing a technique you have done for a while when something better comes along. Keith looks at how changes in software (resampling algorithms) can alter the way you work. In this case, whether to resample in Adobe Camera Raw.

An Introduction to Black and White digital photography
The basics of producing high quality black and white images from your digital camera. An extended version of an article that Keith first wrote for Canon in their CPS magazine.

Black and White pictures from ordinary (color) digital cameras
A collection of different techniques showing the many ways of getting black and white from colour.

Printing

Printer test images
Links to all our own Black and White test images, a copy of the Colour PDI image, and links to other sources of printer and lens resolution test images.

Using the X-Rite ColorMunki for improved Black and White printing
A revised version of our B/W test image that incorporates a randomised 21 step greyscale strip for use with QuadToneRIP and generating B/W icc profiles for improving prints using print modes like Epson's ABW black and white printing mode [April 08]

Media test images
A selection of test images for use in determining the best media settings before profiling. Used in conjunction with our article on the importance of media settings selection. [April 08]

Selecting a good image resolution for your prints
With larger prints you can use a lower image resolution - 300dpi is not any form of 'standard'. It all depends on the viewing distance and some of the features of the human visual system.

Cleaning dried up inkjet printers
What we use to clean up all the old printers we get given.

Black and white printer test images
Designed as a harsh but fair test for any black and white printing system, Keith's Test image is available for download.

Using QTR and PrintFIX PRO for better black and white prints
By using the PrintFIX PRO to take readings from a greyscale test target, you can create luminance only icc profiles that can give a noticeable improvement to black and white print set-ups. It can even be used to improve the results from the likes of Epson's new 'advanced black and white' print settings.

Why don't my prints match my screen?
A short article showing why there is more to getting your prints to match your screen, than just calibrating your monitor. It's the vital first step, but you do need to consider some other factors for best results.

When printing with this RIP (on an Epson printer) you need to set the media thickness by using one of the closest standard Epson paper types - this lists them and what thicknesses of paper they correspond to.

Colour Management

Also have a look at our reviews, which have detailed info on colour managment hardware and software. They are usually written to help give an idea of the principles behind the equipment, not just how it works.

Choosing a working space
There are a number of popular choices for working colour space when editing images. Keith shows examples and discusses his personal choices for different applications. One size definitely does not fit all. [March 2009]

Why don't my prints match my screen?
A short article showing why there is more to getting your prints to match your screen, than just calibrating your monitor. It's the vital first step, but you do need to consider some other factors for best results.

Media settings and profiling for third party inks
Keith recently converted an Epson Stylus COLOR 1160 to third party inks. In describing the profiling of a this set-up with a third party glossy paper, he shows how that often neglected aspect of profiling -driver media settings- can make all the difference between a so-so print and one that he would be happy to send out as a sample to his commercial clients.

Beware the colour management tar pit
As colour management hardware comes down in price, more and more people are being told it will cure all their problems. A brief personal view from Keith covering some of the things it is good for, but also why you should be careful to understand why you are doing it in the first place.

The very simple guide to 'what is colour mangement'.
Is the red in RGB the same as a London bus, or a UK Telephone box? A very short explanation of what colour management is, and why you use it.

Introduction to colour management
We have helped many people and companies get into colour management. This article covers some of the key questions we get asked and provides links to the many colour management related resources on this site.

Zeiss Flektogon 20/2.8 on a 1Ds Mk3
Using an old manual focus M42 screw fit lens on a modern digital SLR. Works well, even if a bit soft at f/2.8. Having a go with manual focus lenses is (IMHO) a good way to help think differently about some aspects of your photography. [May 2009]

Autofocus accuracy check
A method for checking the autofocus (AF) accuracy of your lenses and digital camera body. A (downloadable) test image, when shown on a screen allows precise testing of focus accuracy through the moire patterns caused between the pixels of your screen and camera sensor.
