Notes on how to correct images in Photoshop.

Firstly, press ‘F’ to have a grey background: this keeps you focused on the image.

To preview on a black background, press ‘F’ again.

A shortcut to the ‘grab’ tool is pressing the spacebar

Cmmd+alt+0 zooms the image to the pixels

Cmmd+0 zooms to fit the screen

Homage to a Precious Object

After scanning a negative using the Nikon 1000, the image will not be in grey scale therefore the first thing to do is to go to Image>Mode>Greyscale 

Then, to make sure you have the correct zone system from 0 (absolute black) to 10 (absolute white), go to the layers tab and click on the black and white circle, then press ‘levels’. A histogram will appear and hold ‘alt’ and click on the arrow on 0. the image will appear in black and white; when fragments appear as you drag the cursor, let go of the mouse. Do this with the absolute white. 

This is with the altered zone system and greyscale

To adjust the exposure, click on the black and white circle and click ‘curves’, you can then adjust the curve and see immediate results. 

Adjusted curves and paint brush

Because these act as layers, you can go hide layers to see how the image has changed.

You can use the pain brush tool to dodge and burn the image further.

It is important that the image is saved as a Psd ( photoshop file) with its layers so they can be readjusted.

The image should be also saved as a TIFF and flattened- this is so that the pixels are not compressed and detail is not lost.

The image can be saved in JPEG, although this will lose detail, it makes the files easier to email and upload.
