Guardian Camera Club: martin h's portfolio review

Through the Square Window... You've made bold use of colour, composition and cropping throughout your work. I particularly like this image; the black lines of the window frames create a strong geometric framework, cleverly segmenting what would otherwise be a relatively ordinary city scene, while the panes themselves provide curious distortion. The streak of red from the carriages combined with the unusual hue of the skyline adds vibrancy, while correct metering and post-production has ensured this image has optimum contrast and saturation Photograph: martin h/flickr

Square... In essence this shot is simple but clever; by juxtaposing the arch of the iconic logo with the rectangular tiling and the word square you've shown you have a creative eye and playful intent. However, tweaking the curves in Photoshop would help kick the colours, giving them the same potency as in the previous picture, while a gentle counterclockwise tilt is also needed to correct the angle of the black lines Photograph: martin h/flickr

Passport to... 'We were already running late, but I just couldn't resist hanging around the platform to take a few shots (I seem to be developing a bit of a habit for taking pictures underground)'. This image has suffered from the restrictive crop you've chosen. The scene itself possesses a horizontal dynamic by virtue of the speeding tube train, but this intrinsic momentum and therefore the eyes of the viewer are abruptly halted by the square framing. Noise from the high ISO speed has also become a problem (notice the grain throughout the floor in the bottom right) although this could be eradicated in post production. Better still, use a tripod and reduce the ISO speed when composing the shot Photograph: martin h/flickr

E ... There's something about this phone box image, particularly the depth and detail in the red paintwork and the tightness of the crop, which is especially eye-catching. A really nice shot Photograph: martin h/flickr

3... Comparable to the previous image and, consequently, I'd not present both in the same folio (unless of course the entire set comprised very tight, striking images of this ilk) Photograph: martin h/flickr

Loveshack... 'After a very grey and wet start to the year, the sun finally came out this weekend'. This shot is as charming as it is vivid. I'd be curious to know what a landscape version of this scene looks like; the vertical framing draws my attention up towards the tip of the lamp-post, whereas a wider shot could emphasise the expanse of colourful doors. On the whole this is an accomplished set. All of the images contain flashes of colour and, in some instances, intelligent disection of detail or attention to geometry, but having three London Underground photographs leads me to think that you could/should perhaps apply these motifs entirely to one such subject matter Photograph: martin h/flickr
