Texture Maps



original picture from cgtexture
Creating textures can be done in a Photoshop best done using high resolution pictures. To find high resolution pictures cgtextures.com is a good place to start. For my texture I chose a rough rock texture and began to alter it in Photoshop. To begin my first step was to offset my picture so it the pattern would continue when modeled. Then I began doing small changes like the color by laying a light color of brown and adding a soft light blending layer. From there many adjustment layers where added. I also added depth in between the top where the crack divides the rock. After I adjusted the color of the rock I then started to paint over it. Different brushes like a splatter brush were used to paint blood. To make the splatter look so unoriginal I erased some away. Many different tones like grey and dark brown were painted to the rock to make it look aged. Many different blending layers where used like lighten, lighten color, subtract, and saturation were used on all different paint layers. This was now finished and was my foundation for a texture that was now going to be put into a program called Crazy Bump to get different texture maps.

Night to Day: Matte Painting


To begin my process I first removed the sky from the original background. I did this by using the color range on the sky and after that applied a refine edge for a better selection. Then I placed my selection in a layer mask. Next step was to remove the people and tent. The spot healing brush was used to accomplish the removal of the unnecessary items. While doing the spot healing process some of the railings from the building were taken away, to get back these railings the clone stamp was used with a soft brush. For the remaining development of turning this building into a night scene, adjustment layers were the basic fundamentals. Working with the building, first adjustment layer I used was the brightness to really bring down the shadows. Next was the levels and this brought out some of the mid-tones back into the image. I slightly applied some curve to the image to gather some more darkness. One major adjustment layer was the hue/saturation. This brought out more of the dark tan colors in the building and the green in grass. Lastly the photo filter was used to add a slight shade of violet over the image. Now working the sky was my next goal. I added brightness/contrast, exposure, and color balance were the adjustment layers I used to get a fitting picture to match the building and its lighting. Also I duplicated the moon to add to another layer where overlay blending mode was used.

Matte Painting Pratice: Cliff


In class we are now working on matte paintings. Matte painting can be a photo or multiple photos combined with painting done over to create a whole new mood and/or scene. Given three photos, I had to put them together to create my matte painting. Only beginning the process we are just working with adjustment layers to color correct the images to fit together. I begin with the photo of the man, which he was removed him from the background. I did this by using quick mask tool and I decided to remove the background instead of painting over the man to get the selection. This seemed easier to me after examining the photo. Refine edge was used after getting my selection were I did a few modifies like smooth edge, shift edge, and contrast. After that I then placed my newly selected man into a different background which seemed more adventurous. Now with my man in the new background I needed to replace the sky. Again I used the quick mask tool to on the sky to get a selection, after that I deleted it to make room for my new sky. The photo of the new sky to my convenience fitted nicely and all I had to do was insert the photo. To begin color correcting I started using color balance on the entire photo and brought out colors I thought necessary. Then hue/saturation was applied to lighten up some of the colors. Now I began using levels separately on the three different images to bring the shadows and mid-tones to the same level. Brightness/contrast was used on the sky and the man to help with the balance. To help finish my piece I added a warming photo filter. Last adjustment layer I added and I thought was necessary was the vibrance and this made the image to look gloomy. My one thought on the piece while working on it was the achieving a nondestructive work flow. It’s a step I missed but it was only while working the quick mask.

Color Correction 2

 
To the left you see a photo that I have taken from Millennium Park in my Chicago area.  From it I will display more color correction techniques to improve this photo. To add more dynamism I selected two objects from the photo and individually developed upon them. The two objects I enhanced were the blue and yellow circles. I selected these by using the same methods and that is by means of color range and quick selection tool. After which I manage to a get selection around my objects I then applied a refined edge to get a more thorough piece. From here I knew I wanted to work on these objects first and then balance out theoverall photo/image. Adjustment layers were utilized and will always be executed from here on out be to perform a non-destructive work flow. On the blue circle brightness/contrast, levels, and hue/saturation adjustment layers were used to achieve a more lively blue. Next for the yellow circle the same adjustment layers were repeated as the blue circle, but I removed the curves layer later on to better fit the piece. Also with the curves layer removed it showed more shadows around areas where needed that brought out the shapes of this artwork clearer. Now with both circled objects color corrected it was time to fit the background appropriately with those. The first adjustment layer that was used was the color balance. This did an alright job of bringing out the green in the trees and it slightly effected the overall environment. It was not until I applied the hue/saturation layer to get more real green for leaves and cleaner quality for the concrete and buildings. Also througout using these layers I kept in mind the Crown Fountain (tower with face in the background) to develop and keep its color. Finally the brightness and levels layers were the last touch to my photo to bring a pleasant clear day. You can see resluts below.

Color Correction 1


Here are my color corrected pictures. Displayed on the left sides are the original picture and the right side is my work. So first is the bird which I ended up having an old photo feel to it. Right away I noticed an issue with the upper left corner that casted a shadow, bringing the brightness up in the photo made that part very distorted so I decided to turn the brightness down. By bringing down the brightness it lowered many tones of the pictures colors, so my next step was to use the levels tool to bring out some mid-tones along with a slight brightness to the birds feathers. Still the photo had an unnatural look and to fix this I added curves that improved the red color of the bird’s beak and at the same time incorporated a nice mellow yellow to overall photo.

Next for the rooster in the shadow I immediately knew I wanted to make it a day scene. Being the photo was really dark I started with the levels tool to quickly get a rough day scene. After that I used blue channel within the curves tool to lightly add blue to it. Now at this point this I kept rolling and decided if I was going to add brightness/contrast to this photo it was no longer going to be a day scene, but an morning scene with the idea of the sun being above the rooster. With the limitations of only use the top image adjustments for Photoshop for this assignment I used curves again to bring some color in the photo. Lastly to convey a shine around the roosters head and back the levels tools was used.

Now for the Quirigua monument I started off going for night scene. I do so at first with the brightness by lowering it. Then with the levels tools I ended up bringing out a cleaner darker green for the leaves and the grey tones with the monument. Now to my surprise I wanted to make to sky darker and so I thought that by using the blue channels within the curves this would do the job, but instead it made the trees and grass greener. Here is where my original idea switched from night to just improving the photo overall into a beautiful day. I went and added a second brightness/contrast and notched them up. And lastly I incorporated another curves this time from the green channel and this made everything come together attractively.
