before and after


My first picture is the moon on September 14, our Mid-Autumn Festival. From Dr. Robin's suggestion, I cropped the picture and realized the effect presented is definitely much better. I changed the size from W326 H435 to W126 H113. After, I edited some of the other features, you also noticed the image being clearer and more distinctive than the original. The exposure was changed from 0% to 84%, the contrast from 0% to just 1% (this was best left alone), and the saturation from 100% to 140%. In saturation, less saturation (129%) led to a darker background with less clouds while more than 140% saturation led to a yellowish tint appearance of the moon. The hue at 50% showed the moon to be more distinctive as well. Sharpness varied; if the percent moved from 0 to 40, the picture has a grain or sand background effect to it. After 71%, the moon becomes blurry. I left it at the original setting of 4%.


My second picture is of a tree where I try to catch the sunlight shining through it. I went through each option and selected some and left some alone. The following features were used. Colors were enhanced greatly as you can see the difference from the before and after photo. Tilt was not used. The exposure was decreased from 4% to -29%, contrast increased from 1% to 44%, the saturation from 100% to 179%, and hue from 0% to 11%. The saturation effect brought out vivid colors compared to the dullness of my original. On the sharpness, I increased the percent from 0 to 49. From the range 0% to 49%, the picture looks fine, less than 0% or more than 49%, the picture becomes distorted or stifled. Overall, my concern about this photo is the sun peering through the tree. I not sure the image or reflection is what it should be. Any suggestions?
Question-I tried to add text to my picture (either on or around it) with the words "before" and "after," but could not figure it out. Do we do this before we upload our picture or is there a way you can edit it while in your blog? I tried doing it while in the blog, but was not successful. Also, what about the editing the location of your picture in the blog. I used the selection of none, right, center, or left offered initially when we begin to upload, but I actually uploaded the tree first and moon second. I thought the tree photos would be first, but when I uploaded the moon photos, those took precedence over the other. So, do I assume, you work from bottom up when uploading the order of your photos?
