I used Photoshop but all the edits can be done on the most basic of photo editing programs.
1. Black & white or color? Sometimes with skin tone issues, it may be easier to eliminate the color. Her PJs would have turned out lovely in B/W all that contrast but her skin would look muddy--a "term" that manages to make its way into almost any and all discussions I am having about black and white photography. I opted for color to get all that delicious baby skin color and pop in her PJs.
2. To crop or not? Being a location (I'm hearing this called environmental photography) photographer, I couldn't part with the house details even if it only included a small portion of the frames in the hall. I love placement, which is why I rarely studio shoot.
3. Brighten up her face using CURVES. Careful to not blow out(over brighten which results in lost details) the left side of her face. I had to use the SELECT tool and only brighten the right side and bottom portion of the image.
4. I'm old school. Worked in photo labs and darkrooms so I went to the old standby of COLOR BALANCE. I think it pays off to learn the difference between majenta - red and cyan - blue. Adjust to her skin tone. I always tend to adjust for a warmer skin. You may like it cooler with a little more blue in it.
5. SHARPNESS. The image is a little soft. I used a tool that I have never used (a ha...I'm learning too) SHARPEN under the FILTERS. I don't think I used too much. When you do, it starts to look like someone has drawn an ink line around all the defined/harder edges- particularly on the eyes and it can look overdone and unnatural.
6. She had a bit of the sweet baby shine on the her chin and a tiny mark on her cheek. I CLONED that out.
7. DODGED (brightened) her eyes a touch. VOILA. FINI.
