So far this is one of my favorites of Morro Rock pictures. I did most of the up front work on my Galaxy S22 Ultra phone but had some trouble when it came to using the Double Exposure feature. It did not want to complete the operation when I tried to import the second image. I had to perform that operation in Snapseed on my Galaxy Tab S7 tablet and finished the final image there.
This is the original image taken with the camera on my Samsung Galaxy S22 Ultra phone.
After cropping the original I use some of the options of the Tune Image tool to adjust the Ambiance and Brightness. This allowed more detail to appear overall especially in the rock.
I used some of the filters to give the image a little contrast and changed the colors. The next black and white image was imported over this one using the Double Exposure tool.
I made a black and white version with a bit of drama added and grainy appearance. This image was imported over the previous color image using the Double Exposure tool.
Here is the result of using both of the previous images using the Double Exposure tool. After playing around with the opacity slider I decided the default 50% opacity setting gave the best result.
In this final version I used the Brush tool to increase the saturation in the sand and waves and the green vegetation at the base of the rock leaving the sky as is. I also used one of the Frame options to give the image a little bit more interest.
