Trickier invisible mannequin items include sheer, transparent or translucent materials, fabric with cut out details, or a mixture of all these elements! There are a number of different approaches to photographing these styles, a selection of these are shown here.
Have you always been scared of increasing the ISO on your camera in dim light because of the resulting noise in the images? Has this discouraged you from taking pictures in low light?
Fret not. This tutorial will take care of all your ISO noise anxieties and will let you go trigger happy during night shoots.
Noise reduction in Photoshop
- Open the image on which you need to reduce the noise.
- If you see the image panel, you’ll notice that the image will be opened as a background layer. Create a duplicate of the background layer (just in case).
- Having selected the duplicate layer to go to Filter -> Noise -> Reduce Noise. A new window will open up with some sliders in it. Let’s break them down one by one.
- Strength: This slider, affects globally. That means it will eliminate the noise pixels in the overall image.
- Preserve details: Pixels tend to get blurred while reducing noise. The preserve details slider will bring back the texture and other small details in the image. Different combinations of strength and preserve details slider work differently for different images. You will have to experiment to see which combination gives the best quality.
- Reduce Colour noise: This slider will reduce any floating colour pixels due to chromatic aberration.
- Sharpen details: The blurring of noisy pixels may result in reducing the sharpness of the image. Use the sharpen details slider to restore sharpness in the image.
- At the end of all the sliders, you will see a checkbox that says “Remove JPEG artifacts”. This will remove any noise that may occur while saving the image as a JPEG.
- If you want to make noise reduction specific to the RGB colour channel, click on the advanced tab.
- Select the desired colour channel and make the adjustment to the strength and preserve details slider.
- Once you are satisfied with all the changes, hit ok and the edited image will open in Photoshop.
- Unhide the layer on top to reveal the background layer. You will notice that noise has reduced from the original layer to the duplicate layer.
- Save your image and you are done with reducing the noise.
Try more night shots
Now that you know the secret, try more night shots. ISO is a very good feature in digital camera if it only wasn’t for the resulting noise. Hopefully, camera manufacturers will try to come up with ways of minimizing the noise grains at high ISO but until then, this little Photoshop technique should do the trick.
An image with a transparent background might be placed against a website background. This gives a Web designer flexibility in placing the image on the page, and it can help make the file size smaller versus creating a large background file with the image included. Not all image file formats support transparency, so the two file types to use are GIF or PNG. Most image-editing software that supports layers can create an image with a transparent section.
Create an image with a transparent background. Look for the setting in the New File dialog box that specifies the background color. Choose “transparent background” from the list, or check the box next to that option.
Open the image you want to add to the transparent image. This is probably an image with a background you want to get rid of or an image that has a section you want to make transparent.
Copy the image by selecting “Copy” from the “Edit” menu. Go back to the image created in the first step and select “Paste as New Layer” from the “Edit” menu.
Use the “Magic Wand” or “Lasso” tool–it may also be called the “Selection” tool–to select the area you want to be transparent. Select “Delete” or “Clear” from the “Edit” menu to erase the area selected, making sure the layer you created in the previous step is the active layer.
Erase any stray bits you may have missed using the “Eraser” tool, making sure the image layer is still selected.
Check to make sure you can see the “background” through the part you erased. Most image-editing programs display a gray and white checkerboard to signify a transparent background, so you should be able to see this through the part of the image you erased.
Save the file as a GIF or PNG file. Make sure to specify the option to keep areas of transparency.
