Excuse me, how to light the LED bulb, how to shoot it and how to retouch the picture?

Step 1: Start photoshop and open the two pictures you need! Step 2: A modification box will pop up to modify the pixels of width and height. Pay attention to the constraint ratio in the red line below! If you want to change it to a non-proportional size, tick it off! Then resize the two pictures to the same size! Step 3: Many JPG images in photoshop are locked. Double-click the background item in the layer and an option box will pop up. Select ~ to turn the background into a layer! (Similarly, so is the other picture. But pay attention to change the currently edited picture by clicking on it in photoshop, so change another picture. Step 4: Select the tool on the left above the left toolbar! Then click on a picture and drag it to another picture! At this time, there should be two layers in the layer. Step 5: Open the window animation in the menu bar. Step 6: Click "Copy Current Frame" in the animation toolbar. After copying, two frames will be displayed in the animation! Step 7: Click the "excessive" button in the animation tool! After clicking, an excessive dialog box will appear! Select the number of frames you want in "Number of frames to add", the default is 5, here we also select 5, and then click "OK" to display 7 frames in the animation bar! Step 8, see if the current layer in the layer is the above picture. If not, click Change the current layer! (Note that the blue bar shows the current layer! ) After selecting the current layer, click the second frame of the animation bar! The second frame after clicking should be blue! Then change the transparency in the layer bar! Change it from 100% to 80%. Step 9: Then select the third frame and change its opacity value to 60%. Step 10: Click on the fourth frame in the same way! Change its opacity value to 40%. Click on frame 5 and change its opacity value to 20%. Step 11: Click 1 frame, and click "Select frame delay time" to pop up the menu! After selecting a delay of 0.2 seconds, the bottom of the frame 1 will become 0.2 seconds. Of course, it can be changed according to your preference. Step 12: Click on the seventh frame, and delay it by 0 as above. 2 seconds Step 13: Click the "Play" button. You can see the effect. Step 14: Prepare to save, and set the optimized values before converting into GIF files! After presetting a project and changing its value to GIF 128, select "Save Optimization Result as" in the file menu, select a file name, and then press OK.
