OpenCV imwrite gives washed-out result for jpeg images

Question

I am using OpenCV 3.0 and whenever I read an image and write it back the result is a washed-out image.

code:

cv::Mat img = cv::imrea

As @Micha commented:

cv::Mat img = cv::imread("dir/frogImage.jpg",-1);
cv::imwrite("dir/result.bmp",img);

I was always annoyed when mspaint.exe did the same to jpeg images. Especially for the screenshots...it ruined them everytime.
