Re: A thinner sensor stack may be possible after all!
Yes that is the link - download the \"Adobe DNG Flat Field plug-in\"
Very easy to use as long as you
1. Set your RAW images to \"Copy as DNG\" when importing into lightroom - that way you can start working on them with the plugin immediately without having to convert manually first
2. Make sure that you capture a \"correction\" image with your lens set to infinity - you should ideally capture an image at each aperture but I tend to take just two - one wide open and then another at f8 which seems to work well for most correction purposes. I use piece of white opaque perspex diffuser in front of the lens and then aim the lens with the perspex towards the sky and have found that this gives the best results.
3. Import the correction image into Lightroom and then save the converted image into a separate folder.
4. Select the image you want to correct and then click file/plugin extras and select apply external correction and browse to the folder where you have saved the \"correction\" image to.
5. I usually correct both colour and shading but sometimes correcting for colour only works well too.
You will only have to create your \"correction\" images once for each lens. Once you have your lens correction profiles setup and you \"copy to DNG\" all your raw files on import only step 4 and 5 has to be executed.
