Lightroom: Using Grain in Your Images

Post 28

Series: Introduction to Adobe Lightroom®

Looking for that little something to distinguish your images? Adding Grain could be the perfect thing.

Against the Grain

The tool Grain provides texture to your image. Add a little or a lot with Amount, change the Size of the grain to small or large. Move the Roughness slider to get to that sweet spot for exactly what you are looking for.

Photoshop Tips: How Big Can I Print?

Last Week – Follow Up

Last week I discussed aspect ratios when printing and I said that you should pretty much always expect to crop at least a little when printing.  Someone asked about doing custom print sizes.  If you find a printer that will do custom print sizes then that would eliminate the need to crop your photo.  However, if you are framing the photo, you would need to have a custom frame ordered as well.  This can get pretty expensive, but possible.  This brings to mind printing on canvas, which eliminates the need for a frame.  Most canvas printers have standard sizes/ratios that you have to crop to.  However, you can find some canvas printers out there that can do custom sizes.

How Large?

The other main question folks have when printing is how large can they print.  The answer to this question does not have a definitive answer.  Much depends on personal preference when it comes to sharpness.  You lose sharpness (resolution) the larger you blow an image up to print.  Two things to keep in mind are:

  • The dimensions of your digital image
  • PPI (pixels per inch, or resolution)

Image Dimensions

Each camera will have different image dimensions depending on the number of megapixels, etc.  My Canon 6D shoots at 5472 x 3648 pixels.  Based on last week’s discussion, if I want to prepare an image for an 8x10 print, I’ll need to crop my photo.  Cropping obviously reduces the dimensions of my photo.  The more I crop a photo, the more blurry it will look when I blow it up super large.


In very simple terms, this is the amount of clarity or sharpness your photo has.  Photographers vary on what they say is the minimum amount of resolution you need when printing.  Some say you need as high as 300 ppi (pixels per inch).  Others say that they print no higher than 240 ppi and often go lower than that.  Really, the resolution you want will depend on what the print is for.  If it’s for a huge billboard, people are going to be pretty far away from it so you can get away with a lower ppi.  If people are going to be inspecting the print up close and personal, then you might want 240 ppi.  I would say that a good rule of thumb is to be somewhere around 200 ppi.

The Bottom Line

If you know your image dimensions and the minimum resolution that you are willing to tolerate, then it’s just a matter of math from there.  Take my picture (uncropped) at 5472 x 3648 pixels.  Say I am willing to go with a 200 ppi resolution.  Then I just divide my picture dimensions by 200. 

5472 / 200 = 27.36
3648 / 200 = 18.24

In other words, I could print my photo at a size of about 18x27 inches.  As that is not a standard print size, I would want to crop my photo first to the desired ratio, and then recalculate.

Phtoshop and Lightroom can help you do these calculations.  Below is a picture that I have cropped to a 4x5 ratio.  Its dimensions are 4194 x 3355 pixels (just trust me that it is 4x5).  At a 4x5 ratio, the standard sizes that I can print are 8x10, 16x20, and 24x30.  So how large can I print this without losing too much resolution? 

I’m using Photoshop Elements, but this is similar for Lightroom and other programs.  Under the “Image” tab on the top menu, I go to “Resize” and then “Image Size”

As you can see from the picture above, if I print an 8x10, the resolution will be 419.4 ppi.  This is way higher than the 200 ppi rule of thumb that I discussed earlier.  We can go bigger! 

So I just type in a 20 where the 10 inch width is and everything else recalculates automatically for me.  It says that a 16x20 inch print has a ppi of 209.7.  Right in the sweet spot. 

I was printing this on a canvas for a customer and I knew that 16x20 was going to be too small.  I really wanted to go at least 24x30 inches.  Again, changing the width to 30, everything else calculates (see below):

At 24x30, the resolution is now only 139.8 ppi.  I was worried that the resolution would be too low, but knowing that size was an important factor, I decided to print the 24x30 anyway and inspect for quality before delivering to the customer.  When the print arrived, the resolution quality looked great to me especially knowing that the print would not be viewed up close with a magnifying glass.  Success!

If you would like to see a short video tutorial on this topic, Scott Kelby has a great 2 minute summary:

Wrap Up

In summary, while there is no definite answer on how large you can print something, hopefully this discussion has helped you understand the relationship between the dimensions of your image and the resolution.  Knowing a rough rule of thumb for your target resolution (remember the 200 ppi general target) you should be able to make an informed decision on how big you can print.

Next week we’ll discuss some more useful editing tricks in Photoshop Elements that might make your life a little easier.

Take a Better Snapshot

Yes, I said snapshot.  Seriously people, you cannot be posing and setting up every shot you take of your family and friends.  If you are, stop it.  The whole point of capturing a moment is to capture the moment.  The point is not to re-create the moment so that it looks more like Pinterest photo you pinned three months ago.  That said, there are some ways to make your snapshots fabulous.  Let's explore a few:

1. Remove the clutter.  Take a moment to pick up the clothes off the floor or put some toys away.  Move the trash cans and yard tools.  These things will create a distraction and take the focus off of the subject.  Sometimes this simply cannot be done without missing a moment.  Don't worry too much about it but clean up the background when you can.  You can also use framing and composition to remove clutter with your camera.  This leads to tip #2.

2. Get closer.  However close you are, half the distance.  What are you photographing anyway?  Not the background or the 20 other kids on the playground.  Get close to your subject.  This allows you capture emotion that you won't see from a distance.  It eliminates distractions and clutter and focuses on what's most important.  You'll want to remember details like freckles and kool aid mustaches.

3. Change perspective.  We all walk around looking at things at eye level every day.  It gets boring. Imagine what things must look like from the height of your children.  Much more interesting I'm sure.  Get down on their level and shoot up.  See it how they see it.  Hand them the camera and let them take the shot.  See yourself how they see you.  Or get higher.  Climb a ladder or stand on a rock.  Having your subject looking up gives a different look altogether.  Grown ups love this perspective because it is very slimming.  Just change it up. 

4. Find the good light.  If you are not planning and posing a shot you need the light to be in your favor.  Outside snapshots are pretty easy.  Just find spots that allow your subject to look at you without having to look into the sun.  The shade of a tree or the side of a structure are great options. Or put the sun behind them.  Inside may prove a little trickier.  If you want to avoid using a flash, and trust me you do, keep the windows open. Raise the blinds, pull back the curtains, open the shutters.  Let in as much light as possible.  

Just a few small changes and bit more attention to details can make great photographs out of everyday snapshots.  Just make sure you are taking them.  Don't wait until you think you have the technique down.  You'll learn as you go and probably have some fantastic happy accidents along the way.

Another Summer Movie Day

Horay! I like movies.

Last post we covered a quick vignette tool in the Lens Corrections section. Today we dive in to even more you can do with vignetting.

Which One Which One

Want more options for your vignettes? Close Lens Corrections and go down to Effects. Click on the arrow next to Effectsto bring up Post-Crop Vignetting. Chose High Priority, Color Priority or Paint Overlay. Each of these will give your image a different type of vignette.

Getting In To It

Now use the slider to determine the Amountof white or black to apply to the edge of your image. Change the Midpoint for vignette thickness. Roundness determines how wide or narrow the shape of your vignette will be. Featherchanges smoothness or abruptness of the edge of the vignette. You can also add Highlights or shadows within the vignette section of your image.

Photoshop Tips: Printing and Aspect Ratios

Editing Tips

When it comes to printing there are two questions that come up all the time:

1: I want to print an 8x10, but the edges are being cut off.  Can you help me fix my photo so that I don’t lose anything when it prints?

2: So how large can I print this?

Aspect Ratios

Let’s start with the first question.  To do this we need to understand aspect ratios.  The aspect ratio is the relationship of an image’s width to height.  My digital camera takes pictures with an aspect ratio of 4:3.  By comparison, an 8x10 photo has an aspect ratio of 5:4 (that’s simple math…10 divided by 2 equals 5; 8 divided by 2 equals 4).  It would be nice if they made the camera’s aspect ratio and all standard print sizes’ aspect ratios the same, but that’s not the case.  Even the most common print sizes have different aspect ratios.

Print Size             Aspect Ratio
4x6                       3:2
5x7                       7:5
8x10                     5:4
11x14                   14:11 (almost a 7:5 but not quite)
16x20                    5:4

So what does this all mean?  It means that if you send your photos off to be printed, parts of the picture will be cut off.  There is no magical way to fix this.  It means that you should crop your picture before having it sent off to the printer so that you can choose which parts are cut off and not leave it to fate.  It also means that you should compose the picture before you even snap the shutter keeping in mind that you might need to crop afterwards.

Below is an example of a picture with an aspect ratio of 4:3 that my camera uses.  Compare that to the picture showing how much will be lost when cropping it for an 8x10 print (5:4 aspect ratio).

To sum up, the answer to the first question is that you will most definitely lose parts of your photo when printing…probably no matter what print size you choose.  The sad reality is that there is no way of getting around this.  However, if you understand this ahead of time, you can plan ahead and make sure to factor that in when composing the photo.  That way when you go to crop your photo when prepping it for print, you can keep all of the desired elements in the photo that you planned.  Also, hopefully this discussion helps you know which ratio to use when cropping your photo depending on the desired print size.

Next week we’ll discuss the other common question when it comes to printing…“so how large can I print this anyway?”

Do you have any success or horror stories?  Feel free to post your comments and questions to this post and I’ll be happy to discuss them.  Happy shooting!
