Sometimes you may find that a painting just does not look right. Then you will ask yourself is it worth rescuing or should it end up in the bin. As you will have put a lot of work into it in the first place I suggest you try the rescue operation first before you finally decide to scrap it.
By way of an example I have picked one of my paintings which I was not happy with to demonstrate the process.
The picture on the left shows the original painting. Discussing it with friends I was told that the path looked like it was tilting and the copse in the middle distance looked too small. In other words the perspective was all wrong.
I then decided to start a rescue attempt by first fiddling with the digital photo on my PC. The result can be seen on the right.
Finally I painted over a number of areas to try to improve the original design. It looks better but far from perfect. There are elements in the painting which may be used in a future work. But this one will not be put on display. It is destined to be scrapped. The rescue attempt was worth a try if only for the fact that I have learnt by it.
