Due to the difficult circumstances of where I took the photo (on a moving bus on the expressway, through a window in the evening), my selection of the yellow photos is mostly based on those that have enough exposure, either digitally or practically. For some reason, for some of the pictures that I chose, especially the ones that I have taken in lower light in the evening, digitally increasing the exposure doesn’t work too well because the photographs take in too little light, with some weird red particle effect appearing on some of these photographs.
To minimize this, I have adjusted the tone of some photographs that I believe are very good but a bit too dark for them to be practical. The main changes I have made to certain photos are to increase the exposure and adjust the color profile to that similar to a black and white photograph.
