Print Production: sepia tones

I want to create a sepia tone on my digipak as I feel this fits the genre conventions. In order to do this, I have tried out many different techniques. Below are some of the images I have produced whilst using varying effects and image adjustments to try and create an effective sepia appearance. 

 For the first image, I used to preset adjustments in photoshop to create a sepia tone. However, even after brightness adjustments the photo still looked dark and uninspiring.

Because of this, I changed the technique I was using. I adjusted the brightness levels of the image to make it more vivid. I then created a new layer and using the paint bucket tool, added a sheet of 'yellow' over the image. After this, I adjusted the opacity of this layer to create a subtle yellow glow. 

After seeing that this technique also wasn't very effective, I used the 'image adjustments' menu to alter the levels of saturation. Firstly, I made the image brighter. I then made it black and white, and then using the 'photo filter' menu, I experimented with different presets such as 'sepia' and 'warming tone'. I selected the warming tone as this created a warmer sepia glow and changed the 'density' levels until I decided it look effective. The second image has lower brightness settings and a higher frequency of shadows as I felt the first image looked washed out.
