Cliff Li Posted December 26, 2023 Share #1 Posted December 26, 2023 (edited) Advertisement (gone after registration) Merry Christmas and Happy new year! A few days ago I acquired a Leica Q camera which was bought new in 2017. Recently I noticed that there is a vertical line on the images captured by it. (Vertical in Landscape orientation/ Horizontal in Portrait) I excluded the issues possibly caused by SD Card, Software etc by trying multiple software and SD cards etc I believe it is a line of dead pixel on the sensor which may be solved by pixel mapping which the Leica Q doesn’t have. Leica Q2 have it built-in. Please see the photos attached and offer advice of how to fix it. Pixel mapping? And how? I am in Australia. Your help will be deeply appreciated. Welcome, dear visitor!

jaapv Posted December 26, 2023 Share #2 Posted December 26, 2023 Return it and buy another. This is a sensor fault. It may be possible to remap the sensor by Leica but it may have to be replaced if it exceeds tolerance which is very expensive. 1 Quote Link to post Share on other sites More sharing options...
Cliff Li Posted December 26, 2023 Author Share #3 Posted December 26, 2023 Unfortunately I can’t return it. As I bought this in HK while I was visiting my families. It looks like new. I tested it so thoroughly that I don’t expect any problem. Not until I came home to Sydney and magnified the photo on a 24” monitor to over 100%. any way to fix it please! remapping/mapping by Leica?

Chris W Posted December 26, 2023 Share #4 Posted December 26, 2023 No way to fix it other than fiddling with photo software. You might need to get it repaired. Quote Link to post Share on other sites More sharing options...
Miltz Posted December 26, 2023 Share #5 Posted December 26, 2023 Pixel Mapping fixes random individual pixels. This is obviously a straight line of pixels and I’m not sure if pixel mapping can be applied here. Theoretically if it can it should fix the issue. Only Leica can answer such a question. My hunch is the sensor is defective and that probably why it was sold off, especially if the price was below market. What did you pay for it? 1 Quote Link to post Share on other sites More sharing options...
jaapv Posted December 27, 2023 Share #6 Posted December 27, 2023 The alternative might be to create an action in Photoshop to clone the neighboring pixel lines over the defects. Or make it a droplet. otherwise you’ll have to send it to Leica You might strike it lucky that the dead pixels block the readout and that mapping saves the day but be prepared for a looong wait and a hefty bill Quote Link to post Share on other sites More sharing options...

My hunch is the sensor is defective and that probably why it was sold off, especially if the price was below market. What did you pay for it? The price is just normal. Not cheap or expensive in HK second hand market. Around US$1700. I don’t believe the seller knows the issue as you have to magnify to 200% to see it on a 24” monitor. I discovered it accidentally when magnified, select and darkened the sky. Before that, I edited more than 60 images and didn’t see the line. She is a friend and an amateur who knows nothing about editing. For the time she owns it, it was mostly placed in a dehumidifier. That’s why it looks like new.

Cliff Li Posted December 27, 2023 Author Share #9 Posted December 27, 2023 Q2 got in-camera Pixel Mapping added in a firmware upgrade. Why not give it to Q1 too? That’s what upset me most😡 Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

You might need to get it repaired. Apparently, Pixel Mapping can solve the issue. Leica charged around A$240 ten years ago (in the UK). And I may need to post it to Leica in Melbourne too🥲 Again, why Q2 got in-camera pixel mapping but not Q1🥵 Some camera have in-camera pixel mapping and automatically re-map the sensor every two months Edited December 27, 2023 by Cliff Li more info Quote Link to post Share on other sites More sharing options...

There is a software to make dead pixel disappear, PixelFixer, which only available for PC, not for Mac. I tried the new Removal tool in the latest Photoshop. It works like magic. I may do it to those important images. The line is not visible in normal viewing conditions anyway. Quote Link to post Share on other sites More sharing options...
