Photoshop Blend Modes

Groups of blend modes:

Normal:
- Normal
- Dissolve: treats transparency as a pixel pattern and applies a diffusion dither pattern
Darken:
- Darken: If the pixels of the selected layer are darker than the ones on the layers below, they are kept in the image.
- Multiply (commonly used): Works by multiplying the luminance levels of the current layer’s pixels with the pixels in the layers below.
- Color Burn: Darker than Multiply, with more highly saturated mid-tones and reduced highlights.
- Linear Burn: Darker than Multiply, but less saturated than Color Burn.
- Darker Color: Darkens on the composite channel, instead of separate RGB color channels.
Lighten:
- Lighten: If the pixels of the selected layer are lighter than the ones on the layers below, they are kept in the image
- Screen (commonly used): Brighter than “lighten” and removes more of the dark pixels, and results in smoother transitions.
- Color Dodge: Results in intense high-contrast colors.
- Linear Dodge (Add): Brighter than the Color Dodge blend mode, but less saturated and intense.
- Lighter Color: Similar to the Lighten blend mode, but lightens on the composite channel, instead of separate color channels.
Contrast:
- Overlay (commonly used): Uses a combination of the Screen blend mode on the lighter pixels, and the Multiply blend mode on the darker pixels.
- Soft Light (commonly used): Uses a combination of half-strength application of Screen blend mode on the lighter pixels, and a half-strength application Multiply blend mode on the darker pixels
- Hard Light: Uses a combination of the Linear Dodge blend mode on the lighter pixels, and the Linear Burn blend mode on the darker pixels.
- Vivid Light: Uses a combination of the Color Dodge Mode on the lighter pixels, and the Color Burn blend mode on the darker pixels.
- Linear Light: Uses a combination of the Linear Dodge blend mode on the lighter pixels, and the Linear Burn blend mode on the darker pixels
- Pin Light: Uses a combination of the Lighten blend mode on the lighter pixels, and the Darken blend mode on the darker pixels
- Hard Mix: Uses the Linear Light blend mode set to a threshold, so for each RGB color channel, pixels in each channel are converted to either all black or all white.
Inversion:
- Difference: With this blend mode, similar colors cancel each other, and the resulting color is black.
- Exclusion: Similar colors cancel each other, the resulting color is gray instead of black.
Cancellation:
- Substract: Similar colors cancel each other, and the resulting color is black
- Divide: Similar colors turn white, with the exception of blacks.
Component
- Hue: You get the hue of the top level layer.
- Saturation: Keeps the saturation of the top level layer.
- Color: Same as hue but with the luminance of the lower layers.
- Luminosity: Keeps the luminance of the active layer, and blends it with hue and saturation (the color) of the composite view of the layers below.

In Bold: modes that look different if fill or opacity is selected (other modes will look the same for e.g. opacity=50% or fill=50%)

Adobe CC Lousy Support

I have been trying to purchase an Adobe CC subscription for a year. Have 5 Chat conversations saved. Five open unresolved cases (#0216387593, #0216537262, #0216098627, #0216098411, #0216098835) that have been open for months. Over an hour of useless phone conversation with Adobe Support. If you search for the error message below, you will find more than 170 pages of complaints.

Because Adobe Support s***, I have decided to post the transcript of my last chat:

Sangita: Hello! Welcome to Adobe Customer Service.

Sangita: Hello

nasri: Hello

Sangita: I understand that you want to update your credit card details, is that right?

nasri: not really. all my orders are getting rejected but we can try this. is there a way I can enter my cc first and then order?

Sangita: I understand that you are unable to place a new order, is that right?

nasri: all details follow:

nasri: I have been desperately trying to purchase an Adobe CC subscription for more than a year. I spent countless hours with an incompetent support team both at Adobe and Digital River on the phone, by email and online support (chat). I have subscription at Lynda.com, prezi & others. I pay with my credit cards for Facebook, Microsoft, Amazon, Apple, Play store and others. If you search for the below message at Google, you will find that many people in Lebanon and the MEA have the same problem. I am a teacher at the Saint-Joseph University in Beirut, Lebanon (USJ) and this is my last attempt to purchase a subscription for Adobe CC teacher’s edition before downloading a pirated version on the Internet. My id is: [hidden]@usj.edu.lb The error message follows also attached (by the way, I set the currency to USD and it reverts automatically to LBP. I set the language to English and it reverts to French???): Un problème est survenu lors du traitement de votre commande.

nasri: I have been trying to get help for more than a year!!!!

Sangita: I understand how frustrating it is when things do not work accordingly.

Sangita: I am sorry for the inconvenience caused to you.

Sangita: I will be glad to check and help with this regard.

Sangita: May I please have your email address registered with Adobe?

nasri: [hidden]@usj.edu.lb

Sangita: Thank you for confirming.

Sangita: May I have the exact error message you are getting while placing the order?

nasri: Un problème est survenu lors du traitement de votre commande.

Sangita: Thank you for the information.

Sangita: May I place you on hold for the next 2-3 minutes so that I can research on this issue?

nasri: ok

Sangita: Thank you for staying online.

Sangita: I am sorry for the delay.

Sangita: Please reach out to our Technical Support at United Kingdom: 0207 365 0735 |Ireland: 01 242 1552 |Belgium: 027119960 between Monday to Friday 9 AM to 5 PM GMT for assistance. You can find the support options on http://helpx.adobe.com/uk/support.html

Sangita: Sorry for the above typo.

Sangita: Please call our Sales Support at 0800 028 0148 Monday to Friday 9 AM to 5 PM Australian Time for assistance. You can also find the product catalog on http://www.adobe.com/uk/products/catalog.html

Sangita: Are we still connected?

nasri: I called support twice. spent more than 40 minutes on the phone. they didn’t help.

Sangita: In that case, you can try placing the order again with the below link.

nasri: They put the blame on the 4 banks I deal with and I am sure there is nothing wrong with my credit cards that I use with amazon, lynda, facebook, microsoft.

nasri: Also tried that.

Sangita: Click here

nasri: I already tried this link 10 times: previous chats.

Sangita: I am sorry, please reach the phone support number for further help as you are not able to place the order.

nasri: I have an open case no one is answering and you don’t have a representative in Lebanon and I can’t buy from the US store because I have an edu.lb (.lb=lebanon) account.

Sangita: Is there anything else I can help you with?

Sangita: I am sorry for the inconvenience caused to you.

nasri: Yes, you can send this chat to management and tell them I am going to download a pirated version of adobe CC.

info: Your chat transcript will be sent to [hidden]@usj.edu.lb at the end of your chat.

Sangita: Please reach the phone support number they will help you with the placing the new order.

nasri: I already tried this. and they didn’t help. what part of this message don’t you understand?

nasri: Do you have a customer complaint service?

Sangita: This may be a temporary issue, please try to reach them again.

nasri: I have been trying for a year.

Sangita: Yes, I understand.

nasri: I don’t want to talk to support anymore. Is there a way to send a complaint to someone who can do something about this?

Sangita: But there is nothing much I can do about it.

Sangita: You can try reaching our phone support number for further help.

Twitter double authentication and security via SMS

A few months ago, I posted two tutorials about login approvals via SMS on Facebook and two-step verification on Google.

In this walk through, you will find the steps required to do the same on Twitter. Once these steps are performed, a secret numeric code will be sent to your phone by text message (SMS) every time you or someone else tries to log in to your Twitter account. This code will be required with your password to authenticate you and allow you to log in and access your account.

1- Login to your Twitter Account

2- Go to Settings

3- Click on security and privacy on the menu (left). If you already have a phone linked to your account, skip to step 5. Otherwise, you should see an “add phone” link:

4- Click on add a phone and type your phone number. You should receive a code by sms to verify your phone number.

5- Once you have linked your phone number to your Twitter profile, check “send login verification requests to #your phone number#”. Note that you can also choose to send verification codes to your phone via the Twitter app (rather than by text messages / sms) if it’s already installed on your phone.
