What message did you get on the screen when it finished this ?   Is there now a badpixel.bin file on your cameras SD card?

Why did you do this ?  At one time,  there was a script called badpixel.lua but it has not been needed for several years - the CHDK RAW menu is used to create the badpixel.bin file.

How did you look for the DNG pictures ?  You need to put the SD card into a card reader on your PC - you cannont use a USB cable and the camera software package to find picture unless they have the extension .JPG

Finally,  what camera are you using ?

Ola pessoal,
Acabei registrando nesse fórum, preciso  de uma ajuda.
Possuo Canon SX40,estou com uma duvida, carreguei o CHKD converti Raw em DNG, fiz todo processo certinho, quando efetuo o disparo em fotos Raw-DNG tenho notado nas laterais das fotos um fundo preto,ou se eu efetuo disparo só em Raw, diz imagem invalida. O que pode estar acontecendo de errado?
Abraços!
Thompson!

Hello people,
I just recorded this forum, I need help.
I own Canon SX40, I have a doubt, I loaded the CHKD Raw converted to DNG, I did the whole process correctly, when I make the photo shoot Raw, DNG've noticed on the sides of the photos a black background, or if I place only shooting in Raw, says image invalid. What could be going wrong?
Hugs!

The SX40 is a new port - it is likely the values used to frame the image in DNG format are wrong.

And you invalid image message is normal - RAW is just a dump of the sensor data.  It is not a format that most photography software can understand.  Sometimes those packages get updated to understand CHDK RAW for a particular camera but support needs to be added for each camera.  The SX40 is a new model so support is not available yet.

More information can be found here :

link> CHDK Tools : rawconvert.c

A SX40 é uma nova porta - é provável que os valores usados ​​para enquadrar a imagem no formato DNG está errado.

E você mensagem de imagem inválido é normal - RAW é apenas um despejo dos dados do sensor. Não é um formato que a maioria dos softwares fotografia pode entender. Às vezes, esses pacotes foram atualizados para compreender CHDK RAW de uma câmera especial, mas o suporte precisa ser adicionado para cada câmera. A SX40 é um novo modelo para o apoio ainda não está disponível.
