Vignette effect can be achieved easily if you have a lomography camera, but what if you don't have one?
Well the answer to your problem is Photoshop

So, here are the steps:
1. Open up the image in photoshop

2. Next duplicate the image layer under the menu (layer > duplicate layer)

3. Now open up the Lens Correction filter (Filter > Distort > Lens Correction)


4. Set the vignette option as shown in the picture below.


Then click ok

5. Now we are going to change the contrast level of the Red and Blue channel only without disturbing the Green Channel. So now click on the "Channels" tab
Select the Red Channel only




6. Now adjust the contrast level of the image under Brightness/Contrast (Image > Adjustments > Brightness/Contrasts)
Change the contrast level to 45% and click ok



7. Do the same for the green channel




8. Next, click back on the RGB channel to set all channels active, you should get almost the same picture as shown below




That's all for the lomography effect

9. However you may try to enhance the colour tone of the picture as you wish for. Try using the photo filter which can give a different colour tone (Image > Adjustments > Photo Filter)




Select the "Warming Filter (LBA)" as shown and click ok

10. There are various ways you can enhance your photos. Try playing around with all the effects
Enjoy
