1. Intro: hi. In this class we will be blending some of the techniques in sketch up in food, a shop to produce a concept rendering. We will apply styles to an existing sketch of model exported into an image file, which we will then rendered and photo shop with the use of brush and perspective, tools, filters and so on. This class is great for you. If you're just starting to practise food a shop, we will go over some of the shortcuts, layers and clipping masks. If you would like to focus on Lee on photo shop, the structure of this class will allow you to skip the first sketch up lesson. By the end of the class, we will produce a concept rendering of the kitchen cabinets, and you will learn some of the tools that you can use in your future projects. If this is something you would like to practice, please continue with the class and I will see you in the first lesson. Thank you. 2. Applying Styles in SketchUp: in this lesson, we will be applying styles to our sketch up model. If you're only looking to practice photo shop in this class, you can skip this lesson. Otherwise, please open your sketch of model and find the styles tab in the default trade. Default tab here can be either said to in model or styles. Please select styles, which will show you a number of folders that you can use for different styles. In sketch up, I'm selecting Default Styles folder and then I'm selecting, shaded with textures. This is the style that I'm currently using in this file. The only thing that I updated here is I went to the View menu and I unchecked the axis to just have a white background in this image. And then you can right click on the scene tab and press update. Now I'm going to apply a different style to the same model, so I'm going back to the Default styles tab and I'm selecting sketchy edges. From there. I'm using a pen black style. Once I click on the style, I'm going to right click on my scene tab and press add to add another scene with this new style. Then I will scroll down on the default rate and renamed the scene. I will call it by the name of the style that I'm using. You could use a different style. The airbrush with endpoints can work. Charcoal can work. I just don't recommend to use anything that has too many wavy or dashed lines. But in general mania, styles can work for this exercise. If you decide to change the style, you can select a new style and right click on the scene and press update to save that change. Otherwise, you can go to the file menu export to D graphic to save the style as an image file. From there, you can click options and uncheck the default use view size to increase the resolution. I'm putting about 1000 for the height, which will make the with about 2300 and then you can press okay, rename the file if you like and press export, and then I will go to my previous scene and repeat this steps for the previous style. I will double check the resolution and then we'll press OK and then just double check that both images are saved. And then you can save your sketch of file and we will continue in the next lesson. Thank you. 3. Starting in Photoshop: If you skip the first lesson, please download two images. Sketch one and two from the projects and resource is tab. Then please have the Photoshopped trial installed. And once you open the program, when you get to this window, you can just drag and drop the image with the first style into your photo shop document. If in the future you already have a photo shop document open, you can still use the dragon drop method. Just place the image right next to the first tab off your other document. Once you open the document, let's unlock the background layer for us to be able to work with it further, so click on the lock sign next to the layer. It will become a layer zero and then duplicate this layer. You can press control J to duplicate it, or you can also right click on the layer and selectively cage layer. You can hide the original layer where will use it as a backup and renamed the copy so you can just double click on the name and I'm going to put original image, but you can name it differently. Then let's Dragon drop our second image with the sketch style. And in this case, we're going to place it right on top of the original image on this canvas. And then you can press the check mark or press enter to place this image. I'm going to rename this layer as well. I'm gonna call it's kitsch style. And then I'm going to hide this layer by clicking on the icon next to it. We will get back to it later. And this is good for this lesson. We will continue in the next section. Thank you. 4. Backsplash . Perspective Tool: So here we will be focusing on the backsplash. But before we do that, let's save our food a shop file so you can go to the file menu. Save as and you can rename the file if you like, make sure that the layers box is checked and the format is said to PSD so that we later can edited in a photo shop. Then you can download an image from the projects and resource is folder, or you can also use your own tiles image either. Wages dragon, drop this image into your photo shop document police it by pressing. Enter and then hide the original image layer on the specific image. I want to remove the white boundary. I'm using the rectangular marquee tool to first make a selection and to make sure that the tiles layer is selected, then press control shift I to invert this selection and then you can press delete, which will delete everything around the selected boundary. Then you can press control de to de select. And now I'm bringing theory journal image layer back and I'm still working with the tiles layer. I'm gonna re scale this image, so I'm selecting the move tool first, and then just make sure that the show transform controls box is checked, and you can start scaling this image down. In the newer versions of photo Shop, you can just click and hold and drag from the upper corner down. In the older versions, you will need to hold shift for the scale to happen proportionately and then scale it to a point where about three tiles fit the height of the backsplash, and you can press enter to apply this transformation. Then I'm going to duplicate this layer because I want to have more tiles to cover the entire backsplash, some just right clicking on the layer duplicate layer or press control J. Take the move tool and move. Thus new copy. Place it right next to the original layer, or you can overlap them by one tile, and then he can merge both layers. So select the top one, hold control and select the bottom one, and then you can press either control E to merge layers or right click and select Merge layers. Then you can either press control T and right click on the image in select perspective or go to the edit menu transform perspective. Then you can click and hold in the upper left hand corner and start dragging this image down, and you will start bringing it closer to the perspective of the backsplash. Once you feel like the upper line fits the line of the backsplash, you can press enter, and in this case I'm going to also stretch it in a little bit. I can click and hold and dragged the midpoint on the side to stretch this image. And then, if I need to refine the perspective a little bit again, I can just use the same perspective tool. So this looks good for now, and we can continue in the next lesson. Thank you. 5. Clipping Mask . Paint Bucket Tool: in this lesson, we will be applying edits to the backsplash, and maybe some of the tools might feel like a longer wait to achieve a certain result. But I think it's still helpful in terms of learning for the shop and some of the commends that will help you in the future. So I'm hiding my tiles layer temporarily and on the original image layer, I'm selecting the magic wand and with a tolerance 20 which will give me a more precise selection. I'm clicking on the backsplash with a magic wand, then impressing Control J to make a copy of the selection and based it on and you layer, I'm going to hide the original image just to see the new selection. And then I'm activating my tiles layer back, and you will see that the tiles layer is a little bigger than the backsplash. So to fit the size of the backsplash, I'm going to bring the child layer right above the new backsplash layer, and I'm going to hold out and click between the tiles layer and the backsplash player. This will create a clipping mask which will fit the size of the top layer to the boundary off the bottom layer. Then I'm going to merge both layers, so I'm going to select both of them right click merger layers, Or you can also press control, eat, and I'm going to make a backup copy of this layer just in case. Then, on this new layer, I'm going to color the backsplash, and you will see that on the original image that I showed in the intro, the colors air slightly different that the ones that I got in this recording. But if you want to match the exact colors from the interest, you can just look at these color codes. When you select the pain bucket to later, you can just paste these numbers at the bottom off your color code window. So I'm selecting the pain pocket tool, and I'm clicking on the square to be able to select a new color. Then you can play with the colors if you like or again. If you like to just pace the codes from the previous image, you can do that and then press OK, and you can either just click on the tile to apply a color or for some of them, like for these ones on the side, it will need to select the magic wand and lower the tolerance, which will let you make a more precise selection. So with the tolerance seven, I'm making a selection off one of the tiles, and then I am applying the pain bucket tool. And I'm just using the same concept to apply different colors orange and yellow again. Feel free to play with colors if you like, But once you call her some of the child's, this should look good and we can continue in the next lesson. Thank you. 6. Working with the Brush Tool: in this lesson where we'll be adding some details with the use of the brush. So first, let's actually the brush by either pressing beyond the keypad or clicking on the brush icon on the left and then please download the brush from the project and resource is folder and drag and drop it into your photo shop file. Release it right next to the brush icon on top. Then you can double check if it was imported correctly by clicking on the arrow next toothy brush preview and scroll down. Make sure you see the folder with the brush in it. In general, there are many different brushes that you can use and photo shop. With the Adobe subscription, you will be able to download more of them, and this is just a sample that we can work with from here. I'm going to hide my backsplash pattern layer and create a new layer by clicking on the plus sign in the bottom right hand corner, going to rename the Slayer, call it brush, and then I'm making this election with a magic one on my original layer so that I can only color within the boundary off this selection. Then again, I'm selecting my brush layer and impressing Be again to select the brush and I'm using a great navy color because we will be adding a shadow to the backsplash. And now I just want to demonstrate how the brush works. You don't have to follow this part, but just note that the brush has different parameters of capacity and flow, and lower parameters make the brush semi transparent, as well as allow a gradual build up off the collar. In this exercise, will will be using the lower parameters to create shadows and highlights and gradually add the color layers. And also I'm painting by making the long movements with the brush, as opposed to holding the brush in one place and on the opposite side. Higher parameters off a basset and flow allow the color to be applied faster, but this is not something that we will be using in this exercise. So with this knowledge again, back to our backsplash layer, I'm changing the size of the brush. You can use either the square brackets as a shortcut to do that, or you can also click on the arrow next to the brush preview and change the sites from there, some using about 400 pixels or so, And I'm starting to apply this brush to the upper edge off my backsplash. And again I click holding Dragon release and repeat the steps, and I layer the brush this way, and I also use a different size. So I make the brush smaller, bigger and apply a shadow of that way. And then I can bring my backsplash image back. And if the shadow isn't visible enough, I can either repeat the steps or I can also go to the image adjustments, brightness and contrast and lower the brightness a little bit to make the shadow darker. So this is good for now. We will continue in the next lesson. Thank you. 7. Finalizing the Rendering: in this lesson, we're will be finalizing the rendering by using the brush and applying color to the remaining parts of the cabinets. So I'm selecting the magic wand, and I'm making multiple selections by holding, shift and clicking on the areas on the original image layer. So here I'm selecting the sides of the cabinets first, and then I create a new layer. I use the same brush with a great color to apply color to this layer. I'm using a bigger size of the brush to apply a major Phil first, and then I'm making the size smaller to accentuate the details. Add shadows, etcetera, etcetera. If at any point to feel like you applied too much color to a certain area, you can use the razor tool to remove that color. But for the razor to have the same pattern, we need to assign the brush that we're using to the eraser tool, some selecting the razor to first, or you can press eat and then I click on the arrow next to the brush. I hold control and Ault and click on the brush that I'm using. That way, this brush gets assigned to the razor tool, and I can go over the certain areas off the image to remove additional color. Then I'm using the same concept to apply color to the front of the cabinets to the base into the upper cabinets. Once you color the major areas and you can leave some of them white, let's hide the original image layer and bring our sketch style layer back. Then move the sketch style layer right under every other layer so you can just click and hold on the layer and drag it under all other layers. This way we will see a blend of the sketch style layer with the colors and the patterns that we applied. Let's add one minor detail here. Let's select the backsplash pattern layer. Go to the filter menu, select Filter gallery and choose the cutout filter. In general, there are many different filters that you can find useful. I like caught out because it blends the image and makes it look more like a drawing, and you can change the number of levels and simplicity and fidelity. I'm putting the numbers 83 and three, but you can choose different numbers depending on the look that you like. Then you can press OK, and this is pretty much done. If you want to sign the drawing, you can make a new layer. And I'm using the Kyle Ultimate pencil brush under the dry media brushes and with a black color just signing this drawing. And then you can save this image. Go to the file menu, save as select J peg and press. Save with the maximum quality. I hope you enjoyed this class. I look forward to seeing your projects and please let me know if you have any questions. Have a great day by
